I’ve just gone back to Win7 after 2-3 months of trying to get on with 10. It’s sort of OK, but had hassles with recognising my DVD drive on upgrade, and most annoyingly, it stopped recognising my keyboard every now and again (it’s a P/S2 keyboard, but a nice one, so I don’t want to change it for a USB one).
It(W10) doesn’t seem to be quite finished – Edge is awful. You can switch to a different browser, but it seems to keep putting Edge back as the default as part of updates; It doesn’t handle colour profiles uniformly (some things are OK, some not – the photo viewer being one of them!). Things like device manager are still there with its old, round edged window, but you have to click through an unnecessarily long sequence of square tiles to get to it. The start menu equivalent turns into a mess when you install more than a few programs, and is populated with all manner of “fun” “Apps” (= useless crap) like a cheap phone by default.
…and I don’t like how it looks with its pointy-cornered windows/tiles.
The computer felt zippy when I first installed W10. It felt equally zippy going from a “working” version of W10 (with some programs installed, etc. – I refuse to call them “Apps”) to a fresh install of W7.
I never switch my computer on to marvel at the operating system – I have some purpose in mind. Having to learn the foibles of a new OS gets in the way of that. I’m familiar with Win7, and it does everything I want it to do in ways that I can understand.
I think I’ll cling on to W7 as long as I clung on to XP! YMMV.
In brief: If it ain’t broken – don’t fix it.
