Microsoft has become very hostile. Recently I have upgraded my PC and that tripped the activation. For some reason I was unable to reactivate (I own full retail licence btw), after wasting time on Google I tried Microsoft support. For a couple of days and a number of consultants trying to force me to give them full access to my machine, asking to upload invoices for the new parts, treating me basically like a thief, they eventually generated me new license key. Now I am scared to upgrade anything in my PC again and then there is that update coming. How on earth it is possible to treat customers like this in 2018? Sadly I use some software that only works on Windows so I have no option, but now I have separate PC only to have those apps and on all other machines I installed Linux. Fuck you Microsoft!
