Agree with all your concerns about W10 "free" backup of your everything functionalities.. but did you check Steam on Linux lately? It's becoming filled with good games that can easily make one forget the ones your a missing out because they are Windows DirectX only. I am just waiting a good racer like Project Cars to work on Linux in order to ditch Windows for good.
If you mean Cortana and Maintenance, those can be set to ignore. I'm blocking MS and the OS works fine. Using NetLimiter to check and so far no protests from the OS. Only OneNote will not sync now. Using Evernote to avoid that.
hmmm... could you post the exact version numbers of those win10-esque updates for win 7? Actually ...perhaps what we need is a thread specific to win updates to uninstall, disable or avoid updating in the 1st place... As I can foresee that this is not going to be an isolated incident, but an ongoing and ever-escalating issue.
