Too little too late,I believe I see why there were so many complaints by people starting to use Windows 10. Between me and a neighbor,we installed it on my pc today. If you take the express lane you are signing up to alow Microsoft access to and permission to use everything you do while using the program. There were two or three dozen places we had to refuse permission for Microsoft to use things I do in the future on the pc. My pc is now lighting fast. Running a bunch of tracking apps and pop ups is enough to keep the average pc busy and slow it down. Maybe that explains why people have different results. Any hoo it's done,I couldn't keep anti-virus protection without 10.
