I switched to W10 way back in the Fall of 2015....when it became available as a Free update. There was certainly a couple of hours getting used to it....mostly getting rid of dozens of Apps on the screen that I had no use for, but for the most part I have my system set up pretty much the same as it was with W7. I've found some applications to be superior....Windows Defender, for example, is an excellent Anti-virus, such that I got rid of the other one I had been using. Those who missed the opportunity to get the free upgrade now either have to pay to upgrade, or get a new computer. When W11 (or whatever decide to call it) comes out, I will get it, and stay current with the latest. Those who still have W7 may not be able to get the new OS free. Heck, there are probably people still using W95, and they would have a bunch of problems if/when they ever decide to upgrade. Bottom line, I like W10 and have had virtually NO problems, other than the initial learning curve....which was no big deal.
