My experience with 10 has been mixed. The bad:
- the virus scanner that does what Microsoft wants, not what I want.
- File Explorer that crashes every few hours on a random operation (this is particularly annoying)
- the plethora of unwanted bloatware
- getting harassed every so often to use a microsoft account, or store my stuff in the cloud - even though the machine is not connected to the internet
- the flat window look. I don't care what the handheld telephones look like, this is a desktop and I like proper borders, and the ability to configure the colours - all of them.
The good: Apart from the above, it does seem fairly stable, and it handles unexpected power interruptions well.
From what I've heard, Windows 11 will be basically a rehash of the abandoned 10X. Whether that is good or bad is yet to be seen. Microsoft engineers can't seem to keep their hands off the UI, always need to fiddle with it, rather than fixing the real problems.
