Microsoft did not learn their lesson from Windows Vista, I see.
And yes, I did

.
Only two of my machines on my network have been updated though. My Windows 2000 machine has an IA-32 processor, so it can't even boot Windows 11, so it'll still run Windows 2000 for now. My two Windows Vista machines are still running Windows Vista, for compatibility testing. I also still have a Windows Server 2019 machine, although it can easily be upgraded to Windows 11 despite not meeting the official system requirements.
