CollabVM Advent Calendar

The CollabVM Advent Calendar is an advent calendar which exists as a designated channel in the CollabVM Discord, which is held every December (not always, however). The advent calendar has been held yearly since 2018, and ongoing. Originally, up until 2021's advent calendar, a new OS (usually an obscure, and interesting one) would get posted every day until the 24th of December.

Now it's a Crusty Windows bootleg ever since it launched in late 2021. In fact, the very last entry of the 2021 Advent Calendar was a Crusty Windows bootleg, by the name of Windows 7 Christmas Edition 2015 created by The Rain, which released to TeamOS.

Usually, a picture of the OS in question would be attached, along with links to download the OS if necessary. In the case of future advent calendars since 2021, it would be links to the bootleg in the Crusty Windows collection and its Crusty Windows Wiki article.

All Advent Calendars from 2018 to now

2021

All of the Advent Calendar entries for this year have pictures linked already. You can find them in the Gallery for this year, among other years.

CollabVM Advent Calendar 2021

Day	OS	Description	Links
1	MINIX	Welcome everyone to the CollabVM Advent Calendar™️. Here, we will post a new OS every day right up to December 24th. Today's operating system is one most people here probably know already, which is Minix. This OS is a Unix-like microkernel which has a goal of being an extremely stable and self-healing system and its designed to be used with very little human intervention. It was first released in 1987. What you might not know, however, is that this is actually the most installed and widely used operating system in the history of computing - having more installations than Linux, Mac OS, and yes, even Windows. That's because it is built into Intel Management Engine, which comes with all new Intel processors. Try it here: [link]	http://download.minix3.org/iso/snapshot/minix_R3.4.0rc6-d5e4fc0.iso.bz2
2	PC-MOS/386	Today's operating system is PC-MOS/386. Quite a technical mouthful. This OS is a multi-user multitasking DOS clone released in 1987 and can run many MS-DOS applications. It also allows you to connect to it via terminal if you care about that sort of thing. In 2017, the source code for this OS was released, with a patch that corrected the 'year 2012' problem which stops files made after August 1, 2012 from working. Grab it here: [link] Source code: [link 2]	https://winworldpc.com/download/40e28099-2fc3-ac18-c39a-11c3a4e284a2 https://github.com/roelandjansen/pcmos386v501
3	EggOS	Today's operating system is EggOS. yes yes, prepare your spam. This OS is basically a demonstration for using Go as a basis for a unikernel. The entire kernel is one giant Go application running on ring0, and there's no processes or anything like that, though there is a javascript interpreter built in. It also has a few programs, networking, and even an NES emulator! It's pretty fun to toy around with so I recommend giving it a Go (eggs dee!) Download it here: [link]	https://github.com/icexin/eggos/releases/tag/v0.4.1
4	Windows 2000 NES	Today's operating system is something you probably won't expect - You've probably used Windows 2000 before, right? Well, have you ever used it on your NES? Yes, that's right. Today's OS is "Windows 2000" for the NES. It's actually a pretty functional OS for your NES and includes a couple of interesting things such as a working Solitaire game, a working calculator, and even a music board. A ROM is attached below. [attachment] [SEPERATE MESSAGE] ...but wait, there's more! There's another NES OS called "Educational Computer 2000" which mostly resembles Windows 3.1 and has a ton of bootleggy games built into it. If your emulator supports it (Nestopia has support if yours doesn't), it can even use a keyboard controller to type stuff in. This OS has the same programs as the Windows 2000 OS, on top of a text editor, a weird word game, and even a Dance Dance Revolution clone. Yes, you heard that right, with this you can play DDR on your NES! What could possibly be better?? [attachment 2]	SuborWin_2000_R.nes Education_Computer_2000_48-in-1_Unlf1.nes
5	ELKS	Today's operating system is the Embeddable Linux Kernel, or "ELKS" as it is commonly known as. You probably used Linux before, but how about Linux on your 8086? Yes, that's right; this OS is a port of Linux to 16-bit! Considering Linux was originally intended from the ground up to run on the 386, this port is extremely impressive, and its honestly one of the most interesting OSes I've ever seen. I highly reocmmend checking it out because its really neat. It also comes with a script to boot it right in QEMU on the Github page. Download it here: [link]	https://github.com/jbruchon/elks/releases/download/v0.4.0/fd1440.bin.zip
6	Ventoy	Today's operating system isn't really an OS, but rather an extremely useful utility called Ventoy. It allows you to boot pretty much any ISO right off of your USB drive. That includes Windows, Linux, ChromeOS, etc etc. Pretty much everything is supported. Its saved me quite a bit of time and I think most people here will find it very useful. Download it here: [link]	https://www.ventoy.net/en/download.html
7	Commodore 64	Today's operating system is the Commodore 64... On your x86 PC! Yes, this OS is literally just a Commodore 64 emulator that boots right up just like the real thing. If you have a very specific setup (an IDE ATA drive formatted as FAT32), it can also read and write to drive 8. It's pretty cool to mess around with in a VM but if you're real crazy you can try booting it on your main PC and seeing what happens. Download it here: [link]	https://github.com/xlar54/OS64/raw/master/os64boot.iso
8	MichalOS	Today's operating system is MichalOS. MichalOS is a fork of MikeOS which adds a lot of really interesting and very unique features, including a password system, a bunch of games, a few programs, and even Mac OS 9-esque menu browser, complete with a desktop wallpaper and screensaver. It's honestly very cool and with a system requirement of 80kb of RAM and a 386 or higher, you're definitely able to run this bad boy anywhere. The ISO will be attached below. [attachment]	https://cdn.discordapp.com/attachments/915471659081805855/918274492155977738/michalos.iso
9	CollapseOS	Today's operating system is Collapse OS. Collapse OS is a really weird OS that has all your standard tools; a text editor, a BASIC interpreter, etc. What makes it weird? Its purpose, which is to be ran by scavengers after The End™️, of course! This OS is designed to run on improvised hardware built from junk parts found in the wild, presumably after civilizational collapse. As weird and Fallout-y as that sounds, its actually a really neat project, and hey, who knows, we might not be laughing once we're all using this OS in our post-apocalyptical world. Download it here (you'll have to build it yourself unfortunately): [link]	http://collapseos.org/download.html
10	Shrine OS	Today's operating system is Shrine OS! Are you a degenerate sinner who worships Satan and wants to go against God's personally chosen operating system? Seek a therapist, or try out Shrine OS, a fork of TempleOS (which I'm sure needs no introduction) that adds several features not found in the original, such as a TCP/IP stack, a custom "Lambda" shell which functions like a classic Unix shell, and even a package manager. It also comes with an interesting clone of wget among a couple other things. It's pretty cool and I recommend trying it out. Download it here: [link]	https://github.com/minexew/Shrine/releases/download/v5.05.1/Shrine-v5051.iso
11	TRON	Today's operating system is TRON, or "The Real-Time Operating system Nucleus" (good acronym). This OS is a Japanese real-time OS that's designed mainly for embedded systems. Though it's virtually unheard of, this OS is similar to MINIX as once being one of the most widely used and installed operating systems, due to its presence on many mobile phones, appliances, and even a few cars, though its been widely phased out. This OS is mostly known by computer historians as it was the subject of intense lobbying by Microsoft, who even managed to get it essentially banned in the US via the Omnibus Foreign Trade and Competitiveness Act. There were a few variants of TRON. Specifically, this version I'll link is a BTRON (Business TRON) distro called Choukanji 5, which was the only one I could find as its extremely hard to find a copy. The download is here: [link] The OS is in Japanese, but there is an English patch floating around. A guide to install this OS in VMware is found here: [link 2] Again the documentation is in Japanese, you'll need to translate it if you can't read it. And an English Language Kit can be downloaded from here: [link 3]	https://mega.nz/folder/SI93mQKS#maGTZfIwe3zMxVfp16TiJw http://www.chokanji.com/ckv/supportdata/mac/main.html http://www.chokanji.com/download/
12	9front	Today's operating system is 9front, which is probably more obscure than yesterday's OS. This OS is a fork of the Plan9 operating system, which if you don't know is a pretty legendary research operating system that's meant to be simple and easy to use (for a Unix system). 9front adds a few new features, mainly Wi-Fi support and drivers, USB support, and a built-in emulator. The entire OS website is basically one giant shitpost and they have a directory filled with bizarre images. What's not to love? Plus, their mascot is an ice fairy. How could you possibly hate that? Download it here: [link] And for those who are curious, their image directory is here: [link 2]	http://9front.org/iso/9front-8593.acc504c319a4b4188479cfa602e40cb6851c0528.amd64.iso.gz http://9front.org/img/
13	Visopsys	Today's operating system is Visopsys, a self-described "alternative" OS for the x86 hardware. The OS has been in development since 1997 and features the usual suspects such as a text editor, a calendar, a few games, and also includes an image editor, an xterm-like terminal emulator, and a few other interesting things. It's not as tweaked or expansive as some of the previous OSes listed on here, but its still cool to play around in. Download it here: [link]	https://visopsys.org/files/visopsys/visopsys-0.91-x86-iso.zip
14	Contiki	Today's operating system is Contiki. Contiki is an absolutely insane OS designed mainly for embedded systems, and includes support for a ridiculous amount of different systems. Want to run a web server on your Apple ][? How about browsing the internet from your Commodore VIC-20? Or maybe sending an email to your grandma through your Atari Jaguar? It's all possible with Contiki. This thing literally runs on everything you can think of (including x86!) and it's honestly insane just how many different systems this thing has been ported to. No ISO download unfortunately, but there is a guide in how to run it in Docker here: [link]	https://github.com/contiki-ng/contiki-ng/wiki/Docker
15	MenuetOS	Today's operating system is MenuetOS. I know most people here probably know this one, but hey, it's still pretty neat. It is a 64-bit (technically also 32-bit but that's basically vaporware) operating system with several features such as USB 2.0 support, internet, and lots of applications. And if you don't choose the floppy version, a ton of different games! Download it here: [link]	http://www.menuetos.be/download.php?CurrentMenuetOS
16	Oberon	Today's operating system is Oberon. Oberon is a single-user, multitasking OS which is written in its namesake, the Oberon programming language. This OS is really a lot more interesting for its technical aspect rather than its appearance, as its one of the few examples of a top-to-bottom design of a full OS, among a few other things. The Oberon language is also pretty fun to play with (honestly, I'd say its a far better alternative to C than Rust is) and the OS itself has a couple of neat utilities and features a full tiling window manager. No ISO download, but I do have a QEMU compatible hard disk image you can use here: [link]	https://computernewb.com/oberon.img
17	Syllable Desktop	Today's operating system is Syllable Desktop! Syllable is an open source OS designed to run mainly on older hardware, but it does run very decently on modern machines. The OS has your usual tools; a web browser named "Webster" based on Webkit, an email client, a media player, and even an IDE. It also has GCC and make, so you could try porting some stuff over if you want. The OS hasn't received updates for a while, but its still pretty neat to see. Download it here: [link]	https://sourceforge.net/projects/archiveos/files/s/syllable/SyllableDesktop-0.6.7-1.i586.iso.7z/download
18	GreenteaOS	Today's operating system is GreenteaOS. Greentea is a fork of ReactOS that aims to be fully compatible and very similar in appearance to the more modern Windows 8/10 operating systems, as opposed to Windows XP/Server 2003. This OS has a lot of weird drama surrounding it, so what's better than a weird fork of React OS that causes big divisions in the OSDev community? Regardless, it's still pretty neat to check out, and if you like ReactOS you'll probably like this one too. You can download an older ISO here (unfortunately I wasn't able to find a new one because the artifacts expired): [link]	https://archive.org/download/GreenteaOS/GreenteaOS-0.5.1-C3EBBC36.iso
19	PureDarwin	Today's operating system is PureDarwin. Ever wanted to use MacOS, but without all the fluff and eye candy? Then PureDarwin is for you! This OS is basically a fork of Darwin that aims to make it more usable as a standalone system, as well as making it more easily usable on servers. It's capable of running a web server, ssh, and even xfce and other common unix tools. It's surprisingly pretty usable and its fun to play around in. If you're interested in MacOS or Apple stuff, I definitely recommend checking it out. Grab it here: [link]	https://www.pd-devs.org/Beta/pd_17_4.vmdk.xz
20	Linux	Today's operating system is Linux... on your Nintendo 64™️! Yes, that's right. This is a port of the Linux Kernel that can run natively on your N64. Before you ask, no, you can't run an N64 emulator on this. There's also no internet, but you do get a nice virtual keyboard along with a few standard Unix tools. You'll need a real N64 with an Everdrive to run this - it doesn't work on an emulator. Download it here: [link]	https://github.com/clbr/n64bootloader/releases/tag/v1.0
21	KnightOS	Today's operating system is KnightOS! Ever wanted to bring your computer to your 2000s Texas Instruments calculator?! Now you can! This OS includes many common utilities found on most operating systems, such as a text editor, a file manager, and even a terminal, plus a couple games to boot. It's pretty cool to check out, and does work in wabbitemu if you don't have a TI laying around. Download it here: [link]	https://knightos.org/download/
22	SkyOS	Today's operating system is SkyOS! SkyOS is a very interesting OS that was originally created as an experiment in OS design. It's intended to be an easy-to-use desktop OS for an average computer user and features many of your common applications, but most interesting of all is that it actually features full working ports of Firefox, Nvu, GIMP, and AbiWord. The OS has been abandoned for many years now and unfortunately hasn't received any updates since August 2008, but it's still really cool to check out and explore. Download Build 6947 here: [link] User: `public` Serial key: `4Q7W5-HTRRW-6WYHW-45KW7-XQLXL`	https://drive.google.com/file/d/1iEIJl-KlXdDmnkXuMkE9sUFne7JVNWyy/view
23	AROS	Today's operating system is AROS Research Operating System (yes, thats actually its name). Basically, AROS is an AmigaOS-like system that tries to be binary compatible with AmigaOS at the API level, so you could consider it the ReactOS of Amiga. The OS features your standard common utilities like a text editor, a web browser (literally called "AWeb") and a text editor, and a lot of software has been ported such as DOSBox and other useful tools. Don't have an Amiga PC? No problem! This OS runs fine on 32-bit and 64-bit Intel/AMD systems. Plus, their mascot is a sexy, skimpy cat. Super exotic!! Download it here: [link] AROS has a few "distros" similar to Linux. I recommend Icaros, but AspireOS should be fine as well.	https://aros.sourceforge.io/download.php#distributions
24	Windows 7 Christmas Edition 2015	We present today's final and best operating system. We've saved the absolute best for last, so get ready... Drumroll please.... 🥁 Windows 7 Christmas Edition!! This specially tweaked totally official version of Windows 7 has an incredible custom explorer theme, dozens of pre-installed and useful programs, and even a Macintosh style dock bar on the top which allows easy and convenient access to all your favorite and most-used programs. Best of all, it's free™️! Download it here: [link] Note that the ISO is about 7 GB in size, so, if you're going to install this from a DVD onto a physical machine you'll need to make sure its dual-layered.	https://computernewb.com/~lily/ISOs/crustywindows/Windows%207/Christmas%202015.iso

Today's operating system is Windows 7 Facebook Edition 2012 by BossKanae. This OS is a masterfully produced slim copy of Windows 7 designed for comfort, security, and lightweight usability. The genius design of the background utilizes every last pixel of the RGB color model, allowing the user to not only test their graphics card, but have a burst of artistic inspiration as the perpetually smiling humanoid face winks at them and points letting them know, "you can do it!". The OS is cut down to a staggering 930 MB, which is over 5 times lighter than a stock Windows 7 ISO. What's not to live, laugh, and love about this beautiful Facebook themed OS? Read more about it here: [link] Download it here: [link2]	https://crustywindo.ws/Windows_7_FaceBooK_Edition_2012 https://crustywindo.ws/collection/Windows%207/7.FaceBooK.Edition.2012.iso
2	PicoXP	Today's operating system is PicoXP! Do you absolutely hate pesky drivers clogging up precious space? Do you yearn to lack even the most basic system functionalities, to the point where window titles have to be written in Egyptian hieroglyphs? Well, have I got the OS for you! PicoXP delivers all of that and more! At just 15 MB, this thing only requires 11 floppy disks to run!! Viruses? A thing of the past - after all, if nothing runs, you can't get infected, right?

3	Windows XP GaNjA EdItIoN	Today's operating system - Windows XP Ganja Edition! What's 'ganja', I hear you asking? Why, it's what all the kids born in the 80s (that is, the 1680s) use to refer to marijuana! Now that marijuana is legal in most US states, this OS can safely be recreationally used without any legal troubles. Time to get into an immersive experience of getting so high, you can't even read what's on your screen! But you don't care, because you're high! Sliff don't kill, as the inspirational background tells us. **WARNING**: CollabVM does not endorse the usage of any drugs. Just Say "Winners Don't Use Drugs"!

5	Windows 8.1 Ubuntu Edition	The operating system of the day is Windows 8.1 Ubuntu Edition! Yeah, that's right. Betcha Linux nerds thought you were so cool, huh?! Well, not anymore, because DilShad Sys has come to assert that Microsoft IS the alpha male of the OS kingdom in his legendary 8.1 Ubuntu Edition. Notice the brilliant satire done against Ubuntu in the default poorly drawn user profile picture, showing Canonical that DilShad knows they don't even have a fraction of his power, coupled with the hysterical mockery of spelling Ubuntu as "ubantu" in the build string of the OS to deliver a finishing blow on Canonical's credibility as both a vendor and an OS manufacturer. DilShad lets you know in this powerful OS: HE RULES, and there's NOTHING you or any pleb on this Earth can do about it. Deal with it, SUCKA!! 😎 👊 🔥 Wait! This just in! DilShad failed elementary school grammar AND preschool art classes. I'm getting an update! He NEVER attended either of them. Well... give the OS a try anyway, eh?

CollabVM Advent Calendar 2023

Day	OS	Description	Link
1	Windows 7 Infinium Edition	Welcome back everybody to the 2023 CollabVM Advent Calendar! You know the drill, we'll post a new OS every day all the way to December 24th. Our first OS is Windows 7 Infinium Edition. Do you wish that windows was more bloated? Are you tired of having to manually download bloatware that you don't need and will never use? At a staggering 7 GB (3 GB larger than the base Windows 7 iso), Windows 7 Infinium has you covered. With more themes than you could ever ask for (I of course mean that literally, as you will never find any use for the insane amount of themes this OS comes with), and a plethora of installed software most of which you will never need to use, you can rest comfortably knowing that your computer has more bloatware than even a new HP laptop, or your uncle's desktop that he calls you over every few months to clean up his latest malware infection (he SWEARS he wasn't trying to download porn again...) If you somehow weren't already convinced, the OS comes with 257 (yes, you read that correctly) wallpapers to choose from. What are you waiting for?

2	Windows 7 Underground 2012	Today's operating system is one that draws inspiration from the most popular racing game franchise of the mid 90's to late 00's, Windows 7 Underground 2012. The name is actually a misnomer, as the default wallpaper is derived from art of Nikki from Need For Speed: Carbon. Multiple themes unrelated to Need for Speed are also installed, as well as the original themes that came with Windows 7. The modifications itself are less function, more flare, similar to how teenagers inherit their granddad's 1987 FC RX-7 and ruin it with a new paintjob that makes even the hottest pink seem tolerable. Though, at least it has something to it, with pre-packed K-L MCP (with MPC), WinRAR and 7-ZIP, Flash Player 11, CCleaner, ImgBurn, Mozilla Firefox 16, and Notepad++. It also has .NET Framework 4 pre-installed, so most applications that depend on it will run. Most of the "non-free" applications are also cracked, such as the "Any DVD Shrink" backup application, the Everest PC diagnostics software, IDM, UltraISO, and Xillsoft Video Converter. The desktop context menu is as unusable as Richie Rich's daughter's Mercedes-Benz, having been filled to the brim with entries that don't seem to make sense or otherwise redirect to normally available Control Panel applets. It's as if they needed to fluff this build with more pizzazz that didn't need to be.. More information on today's advent operating system can be read [here](link) and the direct link to the installation media can be found [here](link 2).	https://crustywindo.ws/Windows_7_Underground_2012 https://crustywindo.ws/collection/Windows%207/WIN7_UNDERGROUND_X86.iso

7	Windows 7 3D Edition	On the 7th day of Collabmas, Dartz gave to me.. Windows 7 3D Edition I'm not sure why this could be named 3D... it's got nothing to do with anything 3D! Maybe if you installed VLC or some Nvidia card with 3D Vision software, but for now, you get to enjoy boring 2D experiences with the K-Lite Mega Codec Pack, an unusably old version of Skype, a version of Paint.NET that doesn't work without updating, some "SSD Tweaks", and some other gubbins, like everyone's favorite spyware, uTorrent. If you feel like pinning yourself in a time capsule, then this is it. 46 themes at your disposal, outdated applications that either need a server or need to update to continue functioning, and if you don't have Aero acceleration, those 46 themes tend to be half-broken. Happy holidays! [image]	https://crustywindo.ws/Windows_7_3D_Edition https://crustywindo.ws/collection/Windows%207/WiN7-3D-EDITION2014.iso
8	Sabily	Today's OS is Sabily! Using Windows? That's lame and disgusting and NOT halal. Do you remember back in 2020, the international hacker known as 4chan got access to the spaghetti code that makes up Windows?

I meant Sabily and use that for the rest of eternity to do your computing. But why Sabily, and not normal Ubuntu? Sabily comes with all the software designed for Muslim users. There's so many, the ISO is 3.29 GB! Rest assured you will NEVER need to install any software ever again. Got an Windows program you need to run?

Do you want to use Windows 10, but without the bullshit and the forced usage of Microsoft Edge or whatever they're calling that crap these days?

You don't even need a modern computer to run it! You can continue using this OS on your eMachines computer just like how you did on regular XP installation. As with every bootleg, authors put only the latest and greatest software. Unfortunately, this OS does not have enough software out of the box to be a "just works" bootleg, though it contains the bare minimum, like WinRAR 5.20, cracked by Mortus for you. Internet Explorer 8 to download Firefox, or some other furry browser. Need to run a game? DirectX 9.0c from June 2010 is pre-installed. Need to watch that movie rip? Windows Media Player 11 is pre-installed. And, if you don't like the Windows 10 theme, there's a total of 7 whole new themes installed!

13	Windows Mac OS XP	My peabrain missed yesterday's advent calendar, so to compensate, we're going to do a special one today. Today's OS is Windows Mac OS XP! This is the OS that started it all! Released by the one and only Fouad Laz, this is the most accurate Mac OS look for Windows you will ever see. Based on Windows Extreme Seven 2009, this is one of the best XP bootlegs around. But what can you do with it? Well, you can browse the web with Firefox 3.6.24, download files with IDM 5.18, unpack files with WinRAR 3.90, kindly pre-activated for you by DamasGate Lover. Do you just so happen to have Small.CH.A on your computer? Not to worry, use the WINDOWS MAC OS VIRUS REMOVEL TOOL, exclusive to this OS.

14	SevenVG 2010	Today's OS is SevenVG 2010! Windows is all the rage nowadays, with Microsoft constantly adding more and more useless features and removing more and more of your rights, people (mostly kids) will constantly constantly tell you how nostalgic Windows 7 is and will bitch at you if they tell you that you use Windows 10. Anyway, we're getting off-topic. Let's talk about SevenVG 2010. This OS is a bootleg of Windows XP designed to look like Windows 7. It's one of the earliest "Windows XP that looks like 7" bootlegs (the other 2 being Windows Extreme Se7en 2010 and Windows XP 7 Royale). Obviously, Windows XP is very old now and is absolutely not suitable for a daily driver. But if you were to install it on that old PC lying around, what could you get out of it? Per the usual, it includes Mozilla Firefox 3.5.8 to browse the web, Adobe Flash Player 10 to run all your favourite Kongregate games, EVEREST Home Edition incase sysdm.cpl wasn't enough, and also 7-Zip 9.10 and WinRAR 3.92, because apparently we needed 2 archivers. Oh, and it includes Yahoo! Toolbar if you need that. If you need a Windows XP bootleg that looks like Windows 7, this is a pretty solid choice! Of course, it's free. And it's always free.

15	FuckYouBill 2009	Today's OS is FuckYouBill 2009! Do you hate Microsoft? Do you hate their newest versions of Windows 11, or you're a Linux user? Stop using normal Windows, Microsoft actually implemented a cryptominer in Windows all those years ago, and whenever you use Windows you are making Bill Gates a morbillionaire in the process. Time to wipe stock Windows XP and replace it with FuckYouBill 2009, which just so happens to remove this cryptominer. FuckYouBill 2009 is not very interesting visually, but it is the largest XP bootleg in the collection, coming in at 6.2 GB! Why is that? It's not just Windows XP, it's Hiren's Boot CD 10.1, Mini Windows XP, Windows PE Full CD and a few Acronis PEs. But that's not all, there's a full Linux Mint 8 live CD incase you don't want Windows and if you also want to install a security vulnerability. But what comes with the XP installation? Well, per 2009 standards, you get Flash Player, Java 6, Google Chrome 2 and even a cracked copy of Photoshop CS4. There's way too many programs to list that comes with this masterpiece. That's not all, It comes with a beautiful bootscreen, and that bootscreen indicates that it is a Plus version, explaining all those bundled programs. And, while it's setting up, you can read the incomprehensible nonsense on the setup billboards. Piter Pen and Goletsa really put effort into this masterpiece, and you should go download this almost 14 year old operating system and install it on your PC today!

WOW!!!), and much, MUCH more. So, what are you waiting for?! Download this OS NOW, and get the fun back into computing!

It's a particularly notable bootleg which entered the collection very early on, and was particularly difficult to find!

Anyways, the OS has received the Rockers treatment - new programs, themes, wallpapers, the "Essential Softwares" filled with cracked programs, and 300 MB of ATI and NVIDIA drivers on the desktop. What more could you want?! [SEPERATE MESSAGE] Many other enhancements have been included. RocketDock is included, along with 600+ gadgets (you'll never run out of them again!), 2 screensavers, and the exclusive Yahoo! Messenger for Vista preview! Very spicy. So, what are you waiting for?!

Lite ISOs are all the rage, with ones based on almost any Windows version you can think of, People have even created lightweight versions of Windows 95. But there's one problem, most, if not all of them are in English. What about the Chinese market for lite ISOs? As many Chinese citizens don't understand english, how will they use these lite ISOs?
