Windows 2000 did not receive updates like XP because Windows XP is a Windows 2000 with more functions, so Microsoft had to allocate a big budget for development the both or XP alone, so the choice fell on XP because it was more decorative and people loved it, despite that in the first ten years there was no significant difference between XP and 2000, the difference started to appear when programs and modern machines appeared from 2010 to present, and with the efforts of blackwingcat it was able to add the missing functions in cores of Windows 2000 at compatibility of software and hardware so Windows 2000 restored its compliance with programs, most programs that run on XP can be run on 2000 with experience, even at the hardware level with the blackwingcat Extended core Windows 2000 can work on modern devices, unlike 98.
Microsoft has made many updates for Windows XP, but most of them are security updates, and blackwingcat made some of them work with Windows 2000.
