Congratulations on the anniversary.
Windows XP was my first system, since I had a computer. I have used it most of my life:
2005-2012 Windows XP
2012-2015 Windows 7 x64
2015-2017 Windows XP
2017-2021 Xubuntu 16.04 x86
And now I miss Windows (XP) again.
Do you encode H.264 on Linux with HandBrake? Unfortunately, HandBrake stopped supporting Windows XP and x86 architecture very early. But there is other software. And I compiled a fresh console x264.exe that works on Windows XP.
