“Fully in control!” (wink, wink)
This happened to me. After months of Microsoft “Would you like to upgrade now?” queries I returned to my computer one day to find Windows 10 installed without my approval. I was livid of course and immediatley began checking to see if my third party softwares were still installed and functional. Surprisingly almost everything was still there and working though I havent been able to get my Microsoft Office 2013 programs to work. Jerks.
