I just moved to Windows 10 after just a few weeks with Start 8 on a new computer--a Lenovo Yoga 3 with 8 gigs if RAM and an M-5Y10c processor. There are some things I'm troubleshooting, including the fact that it sometimes takes a couple of minutes or more to get from the screensaver back to work. Is there a way to turn off Start 10 for a little while and see if the problem is there? I couldn't find a startup item I can disable and re-check for the next boot. I don't want to be uninstalling and reinstalling.

Thanks
