These are keys made available by winworldpc.com.
From the site: "WinWorld is an online museum dedicated to the preservation and sharing of vintage, abandoned, and pre-release software, as well as any and all knowledge associated with such works. We offer information, media and downloads for a wide variety of computers and operating systems. Our collection includes abandonware operating systems (like Windows 3.1 or 95), beta operating systems (like Chicago, Whistler, and Longhorn), abandonware applications (like AfterDark, the epic screensaver software we all grew up with) and more."
"Friendly Reminder NO! No Windows XP!
Microsoft has asserted their copyright status regarding Windows XP. WinWorld respects this and therefore will not host Windows XP. Microsoft still supports various incarnations of this software, and its availability competes with newer Windows product sales. Windows XP is not rare or in danger of disappearing, and therefore has no real place on WinWorld anyway. Anyone who can not comprehend this and requests Windows XP or later will be immediately banned."
This site is my main resource for old OS's that I don't have on disc already. If a disk dies then I DL an image and burn it. They are allowed to do this as well which is really cool.

These are what I use the most and I'm excited that they even have the keys around.
Lay waste.
