Finally had enough...
My main PC and 10 year old HP laptop are now running Linux Mint 17.3 Cinnamon. What a breath of fresh air.
The last straw came when MS decided to start 'polluting' security updates with W10 nagware - plus it took nearly 4 hours to get 11 security updates for W7 on the laptop last week - 3 hours "checking for updates..." then another hour to download and install them. The main PC doesn't take anywhere near as long but the wait is still annoying.
Been putting up with that every month since the middle of last year. Does anyone still believe that the slow checking for updates for W7 - especially after a clean install - isn't deliberate 'sabotage' by MS? I suspected it when all the trouble started - right at the time W10 was released.
Linux Mint was installed, updated and running in almost no time at all by comparison. On the main PC and the laptop.
My main PC actually now has a W7/Mint dual boot - W7 is at SP1 level only - no further updates with NO Internet access allowed whatsoever. Just for programs that don't have a Linux equivalent at the moment. Now I can sit back, relax, and enjoy using my computers again (plus I'll occasionally grab a bag of popcorn and watch the Windows train wreck continue).
