I have told everyone not to upgrade to windows 10 because it will take down their entire POS system, I had managed to get GWX control on most PC's but missed a few. Now this week alone Ive had 4-5 PCs upgrade over night and take down the entire system. At first I thought people knowingly did it, but we had a PC in our own office do it yesterday. Is this even legal? How is this happening?
