[Quoth]

I was giving training, programming, selling etc Windows since 3.0.
NT since 3.5 in 1994.

I agree ME was rubbish. We replaced it with Win98SE or NT 4.0 depending if for games or office applications.

I've loads of engineering software that doesn't work at all on Windows 10, some on no later than XP/Server 2003 and many Visual Basic 6.0 applications that only work (if at all) on 32 bit versions of windows, most of those work on 64 bit Linux under 32 bit WINE. Some of the programmers are dead now.

MS themselves include VM software for Windows 10 and compatibility is so bad that the Compatibility Mode for many older applications is actually an entire copy of XP or Windows 7 on a VM. The SAME file will run on the included VM on Linux but often WINE works.

If Windows is working for someone, or if they are using Windows in a big company, then they don't need to change. If it isn't then Linux or Mac OS are real alternatives.

If Linux or Mac is working for someone, it's crazy to switch to Windows and simply annoying to be told Windows is better. It's different.

Edit:
We had our own Windows server at home from 1995 to 2007
NT 3.51, NT4.0, briefly Server 2003 + CentOS Linux, then Win2000 Server + CentOS.
Then by 2007 we had Ubuntu as server (Later Mint) and Win2000 was only used for WUS for XP, but down to 2 XP so Server 2000 dismembered.

Server has been Mint now for years. Only kernel upgrades need a reboot (at any time we choose, unlike Windows on occasion).
