>>43630264To elaborate on the link posted here, this is a supposed source for Windows XP.
The exact file seems to be from around 2007, as it shows up on Chinese torrent sites, with that date.
It's possible the contents could be from before then, however, as this website:
https://mirgames_ru/forum/winapi/2568 Has a post from 2006, with a link that seemingly had the source, directly from Microsoft's site. So, its possible the RAR may be an archive of the contents of that file.
Problem is, the RAR is password protected, and no one knows the password for it. Reportedly, passwords 6 characters and below have been tested, but to no luck. It's also been speculated that it could be using Chinese characters for the password, but at this time, RAR did not support unicode, so, this is unlikely.
If anyone is able to crack this sucker open, im sure a fuck ton of people would be greatful for this.
