If you're really tired of this shit, then get LTSB.
And you know that based on what? The lack of bug reports? The LTSB population is obviously going to be smaller than the general population, so the lack of reports of it happening on LTSB doesn’t really indicate anything. Besides, the task manager bugs introduced in 1809 is in ltsb 1809 AND server 2019, which makes me inclined to believe that all the windows editions come from the same branch anyways.
What's what integrity checks are for.
Technically there's not much that is stopping me from using it in trial mode with a rearm up to 90 days, because I use it in a VFIO VM anyway. But you probably wouldn't like that either, would you?
