Windows 10 bugs, My 5 year old Toshiba laptop decided to download W 10 on its own last week. I was perfectly happy with the W 7 on it and against my better judgement went ahead and accepted the upgrade after the 2 hr loading process. Some minor things such as deleting a couple minor programs, C cleaner was one. My biggest problem is turning off after 3 minutes or so (sometimes a little longer) and Firefox is crashing much more often. For the turning off, I messed with the energy usage, tried resetting to default and also messed with the screen saver setting which is on none now. No fix yet.
Any suggestions? TIA for any help.
