Hi ich - that's a bit much, sorry. "Plainly you should go with the latest version..." - well, no. W10 works perfectly well, is secure & easy to use. Why accept an OS just because it's the latest version? That doesn't mean it's better than the previous one. A feature you like, or a way of working that you're used to might be no longer available. From the "Update" section in W10 "Settings" -
"Some Windows 10 features aren’t available in Windows 11. Certain apps and features may have additional requirements."
Also - "...depending on how you buy it you may not have much choice" - true, but it's very easy to downgrade back to W10 & it's completely free to do.
Barry - "...it also works very well on my old machines that according to MS can't run it" - but I'd bet you had to faff a bit to get it up & running? (I *could* get it on my old laptop, but the messing around ain't worth the trouble). If not, congratulations, you're obviously one of the anointed. Or perhaps you're someone that just *has* to have the latest of anything & doesn't mind what it takes?
Not having a go at you personally, I promise [:-)], but I'm frankly bored with posts (on any site) lauding W11, when it's almost 50/50 for/against & the "againsts" barely get a mention.
