Well, MS forced an upgrade on my system, absolutely zero option to say no, took me all of ten minutes to utterly hate the lack of taskbar options and usage so I rolled it back which failed spectacularly and left me with a system that wouldn't boot, ended up having to do a full re-install of W10, complete waste of my time to get back to where I was, thankfully the option to refuse the upgrade actually showed up once the fresh install picked it the W11 upgrade. To be fair, the issues with not having a refuse option and the corrupted roll back might very well have been down to BSOD issues I'd had previously due to a faulty CPU but even so, the system appeared to have been working without issue previously, lucky I know what I'm doing with a pc to have been able to sort it, can only imagine the frustration it would have caused a normal user.
