> The same applies to Windows 10! It works fine, sometimes, for a few things. Then it goes nuts. Wipe and reinstall (remove the Dell bloatware) and it's better

The sad thing is Windows 7 and 8.1 worked just fine; they screwed up with Windows 10. I've had both 7 and 8.1 running for years without a problem. But I had a pretty clean Windows 10 installation that tried to update itself and kept rebooting and rolling back. The fact that I couldn't suppress the specific offending update meant I couldn't update the OS anymore.
