alright, but you have to do it only once in every 10 years, so...
back in the XP days, I used a software called "Unlocker" just for this problem. It probably still exists, I don't know, because since Windows 7, the easiest way to find out what process locks a file is to open Resource Monitor (Start search: resmon) and on the CPU tab, using the "Associated handles" list, you can search for the file name and see the process in question (and kill it).
So yeah, Resource Monitor is a useful tool on Windows.
I haven't seen any Star Wars movie.
I started Star Trek from 0 around 2 years ago.
I had to stop at number 2 of your list. (Maybe a bit later since I still watched Enterprise...) but Discovery killed the whole thing for me. I was like... how bad it can be? It's still Star Trek... well no.
Checked out a few episodes of Picard.., I dunno. That's also not necessarily the Star Trek for me. :/
(On the other hand, Seth MacFarlane's Orville was amazing)
where I live (not Japan), trams are updated with a suitcase worth of floppy disks (and these are the more modern trams here)
welp, I'm not sitting on a tram anymore
strangely Network Troubleshooter always helped me when I was out of ideas why the network just... stopped working
tho never said the problem, things just got fixed in the meantime while it analyzed n shit and then it reported no issues :P
Your system ate a SPARC! Gah
What does this mean? Does it has something to do with... I don't know, the Sun SPARC CPUs?
Retro tech. It's not too obscure, especially nowadays. I could talk long hours about how mind fucking blowing was the Amiga and then still how it went down on the drain... tho I just see on the other people that this isn't really the topic that will kickstart (heheh) the party.
I need to find more friends...
for Android I think Connect for Lemmy is the best around. also, it gets literally better day to day since the dev is following the app's community and fixes bugs, implements things from there super rapidly.
My first guess would be filtering out illegal content is something that the operator/admins of the given instance have to take care according to the law of the country the server is hosted in.

Think about it the other way around; you could use Linux on your work pc for the time being and your workplace was fine with that? that's awesome. it's a bummer things changed, but... that's corporate life, bro.
