I hear all kinds of praise for windows 10 everywhere else, like we are preconditioned to treat it as the glorious savior version of windows 8, but I am the only one of my small group of local friends who have not installed it and I just hear horrible things.
* 2 out of 3 cases of a clean install windows 10 had to be repair installed 2 days after the initial install due to key system files suddenly going missing.
* all 3 reported a windows update (which apparently can no longer be turned off by any currently known means) breaking basic features like the calculator until another update came out the next day.
* 1 person reports their app store, and basic calculator(seems to be a trend with basic included tools) as completely nonfunctional, apparently the fix is yet another repair install, they just haven't done it yet.
I used to be a little annoyed that my work from home job forbid us from installing or upgrading windows 10 on our systems 'until further notice'. But now after seeing all that it seems to be for damn good reason.
EDIT: Oh and one of the tools I use at work allows me to remote control a customer's computer when they are too incompetent to follow step by step instructions not computer literate causes windows 10 to BSOD. I can't fully blame that on windows 10, since I'm not sure exactly what the program is doing but it does indicate some kind of fundemental change for the worse in error handling at least.
