proceed with caution
Running Disk Cleanup utility and cleaning up Windows Updates has unwelcome side-effects - all previously hidden updates come back out and one has to hide them again (or risk installing the next actual updates get mixed in). At least automatic updates don't get switched back on (for now knowing MS).
I have not switched yet to Linux but MS keeps nagging me to do so. No excuses at this point but plain laziness (FireFox runs just fine on anything and neither 8 nor 10 has nothing to offer outside of basic OS functionality... and forced telemetry).
