As an IT person, I'm consistently amazed at what people will do on their work computers if allowed.

People log into all their social media accounts, save credit card info for online shopping, save personal passwords, make doctors appointments, etc.

As for weirdest? I was working on a woman's work PC years ago and her desktop was filled with a bunch of boomer-style pro Trump memes. She was logged into her Facebook account on the PC and was downloading them onto her desktop and then presumably posting them to FB. It was stuff like, "I'm a proud Trump girl!" With a picture of a Minion in front of an American flag. Classic cringey boomer stuff.

Another weird one: In college, I once saw a girl using one of the library color printers to print an entire recipe book. Like with full color pictures and everything. The whole thing looked like it was several hundred pages thick, absolutely huge. The library had a sign right above the printers that requested students not print more than 20 pages in full color, so RIP to their toner on that one lol.

I was called in as tech support. On a work PC in a shared office (financial consulting firm), the desktop wallpaper was a full frontal nude of the co-worker sitting across the room.

Worked as a computer tech in college

We had regular clients that would bring in their ten year old laptops to get "tuned up," which normally consisted of removing whatever interesting malware they'd manage to download

One guy would bring his computer and his lockscreen slideshow and desktop would be a rotation of naked women surfing. I never looked through people's stuff because ick, but after bringing it in multiple times you'd have seen hundreds of them

Another woman had an ancient laptop that'd probably shipped with Windows Vista that was 1 core 1 thread. It was desperately trying to run Windows 10 but was drowning constantly. You could watch the startup processes in task manager in series which was pretty cool

Had a woman deliberately hand me her phone open to her photos with like dozens of nudes while she just talked to me normally about whatever banal up issue she was having with her iPhone. Thinking about it I don't think this was an isolated event

Stuff on the devices is typically less weird than the people

Boss called me in because his computer was slow. What I saw was a desktop filled with files, stacked on top of each other and hundreds of open browser windows with hundreds of tabs each and a blurry background image of the building we were in (honestly a beautiful old, restored building but it was his whole identity). I had no words.

Worked as the tech person for an office supply store in the US.

Regular (annoying) customer comes in with his desktop and printer in a cart asking for us to "verify the connections between his printer and computer", because it wasn't working.

Hook it all up to our work bench. It was a Win7 machine or something. Before I could navigate it, he urges me out of the way so he could show me what was wrong.

He opens chrome. You know how browsers will ask you to restore tabs when they close improperly? He clicked that option when it pops up. The first thing I see is a movie streaming site that's in Russian with porn ads everywhere. Just raw dogging it.

He closes that tab to reveal an image of a naked child on the next tab. He closes that tab, and there's another one.

I don't really remember what I did, but in hindsight I wish I had called the police. I think he just ended up leaving the store with his stuff after that, but I learned months later that he came back in to use our self-service copiers and had more pictures, and our store manager threatened him and kicked him out.

One guy I knew had a picture of himself giving finger guns as his background and whenever he unlocked his phone he would smirk at it like “oh you”

It wasn’t his lock screen either, just the home screen, so he knew it looked sketch

I knew a guy that had to come out to his parents (as both gay and a furry) because he set gay furry porn as his lock screen. Not quite sure what the reasoning was there...
