It's the lack of proper QA. People will have gotten from my posts that I do love Windows. I think it should be a fine piece of work but is being ruined by complacency. The head bods at MS seem to think that they are in a position where nothing can take them down. If that is the case they should stop adding features. Add security, performance, optimisation. Make what they have do what it does better, not make it do more worse.
I am very lucky in that none of the PCs I have, including insider testing ones, have yet to go badly wrong (a fast stream one won't resume from suspend if it's put into suspend by closing the lid - pressing the button is fine). But at the point issues stop me bing able to look after the PCs of family members I'll have to make some changes.
Can't do Linux, for your average user it's confusing and too unfinished. So that' leaves me with a short term drop to 7 or 8 (which always worked fine - but quirky) or jumping ship to Apple. I've been toying with the Apple jump for a while. I just need to read up more on reliability of updates, etc. Anyone done this jump that can give any usefull comments?
