We updated four LAPTOPs to WIN 10 when the changeover first came out... This was on two WIN 8.1 Laptops and Two WIN 7 laptops. I run my main WIN 8.1 converted LAPTOP in WIN 7 mode with ICONs down the left main screen and TOOLBAR across the bottom. I am running a PHOTO SCREENSAVER for the background Monitor views. I am using my Windows MS 2007 OFFICE Software including MS OUTLOOK for Email and running either FIREFOX or GOOGLE Chrome on it. Did not sign-up for any of the subscriptions offered with WIN 10. I only use the WIN 10 EDGE for a couple of card games that came with it. About the only APP I am using is the CALENDAR for keeping tracks of my monthly bills.
I have had to reset one WIN 8.1 converted LAPTOPs to its early restore point for problems a few months back. Early on I had to the same thing with one of the WIN 7 converted LAPTOPS.
I hate it when the UPDATES comes out... Always something doesn't work after this happens.
Hoping to get past today's upgrades in flying colors... All LAPTOPS are up and running here just fine...
