Psssst…
Wanna know the real reason Microsoft won’t issue a patch to Windows NT 4?
They lost the source!
That’s right. See, with a piece of software that’s open-source, even if the original source files go away, there’s gonna be somebody out there with a copy of the source. There will be a mirror to download it from, or someone on a mailing list will have every tarball on a CD in their basement. But since Microsoft delivers only closed-source binaries, they didn’t notice at first when someone needed more room on some Windows share and deleted the directory containing all of the Windows NT source code.
But what about backups? Well, they tried using the Windows Backup Utility, but it didn’t work. The index was corrupt or something…
Well, that’s my theory anyway…
