Worth a reminder. Now that malware is often boobytrapped, be sure what you can't lose is on backups.
After an update, my win 10 machine will boot to a generic setup, it loses my software, settings, etc. If I reboot a couple of times or shut down and reboot, everything show back up and it runs fine. Any ideas??
