Alt+Tab goes to a random window instead of being in the order of recency

I shall write a virus that makes the computer play the "USB device detached" sound followed shortly by the "USB device attached" sound. Dee doo. Doo dee. Just that. three or four times a week.

While the computer is on, at random intervals, it shall play the sound of a smoke alarm's low battery beep using audio technology to make it sound like it's coming from somewhere else in your house.

When I was in high school in the 90s a group of us in computer class made a 'virus' that would launch the hamster dance website in all of the classroom computers randomly. We had to put it on a diskette and install it manually on each computer but at the time none of the computers even had antivirus so the school had to reformat them to remove it.

I'd make Windows 11

Edit: Whoops, that's not harmless

Switch the M and N keymaps

Also delete and enter

At first it all seems normal, every now and then a random sound effect is replaced by ominous hooting. Every hour, on the hour, a green owl flashes on the screen for a frame or two, it's eyes boring into you before vanishing. Once every 50 or so times it pumps your volume up, selects speakers as output and let's loose a screeching hoot. Random popups slowly ramping up "Restart your streak today", "Where did you go?", "Duo misses you". At first just once or twice a day, but steadily increasing in intensity till it's one every 23 seconds.

I call bullshit. In the 90s you had to turn a phisical wheel to increase the volume of the computer.
