So, for months I just closed all the "upgrade to windows 10" reminder notifications that kept popping up on my PC.
Then last week, I left my computer idling for a bit, and then came back to find it was in the middle of installing Windows 10 without my permission, the cheeky cunts. I had no idea they would do that, but anyway I had let it finish.
Now here's the thing, everything still works, everything is where I left it, but it's true what they say - the operating system is
literally spyware sending everything including your fucking keyboard presses (yes, no shit) to microsoft, if you just leave it in its default state.
It appears that you can turn all that shit off (which is what I did). I just googled "turn off windows 10 spying" and it led me to this video which seems pretty comprehensive:

Enjoy.
