I wrote the other day that I had a close call, where Microsoft nearly updated my computer to Windows 10 from Windows 7 without my permission. Microsoft's Windows 10 code has become the most annoying bit of malware on my computer. I have had several readers as well as PCWorld recommend the free GWX control panel for making this threat go away. I tried it the other day and it is really easy to use and seems to make the problem go away. I cannot vouch for whether it creates any new problems, but so far so good.
