As for a Cray - that is overkill for asking for medicine or reading SOL?
Actually, even quite old smartphones have more computing power than the venerable Cray supercomputers
Windows update forced on me by Microsoft
This was what finally turned me away from the MS fold - an update was autostarted but failed, leaving me with a laptop which refused to do anything until the update was completed but where the update couldn't be complete because there wasn't enough space to download the update - later I found the fail to be because of cruft from previous updates which MS kindly hid from view, occupying most of the spare disk space. So now I buy second-hand laptops at low price (sold cheaply because they can't reasonably run the latest MSWin), drop a lightweight Linux onto them, and have a good and responsive system (at least until I have Firefox running with about 800 tabs open across 10 windows, and Ffx is trying to use >10GB of my 2GB RAM causing it to thrash doing swapping). The (temporary) cure for that:- kill firefox and restart it. On MSWin - hope that I can close enough tabs and windows to be able to do an orderly restart without it crashing first (or at least hope that it's Ffx that crashes, not MSWin), then restart, then try to remember what I was doing
