Happy days
I remember supporting an IT sales team back in the 90s. Both the tech manager and I used to get in before the team arrived so we could get set for the day. (i.e. set up the coffee machine, and empty the first jug before the sales team arrived.)
Unbeknownst to me, the Tech Manager had installed a something "extra" on the head of sales PC - because, well he was head of sales and ALWAYS tinkering where he shouldn't and visiting websites he shouldn't after hours.
HoS arrived, sat down and booted his PC and shouted out loud that there was a problem. We both rushed to his desk and there, in the middle of the screen was a window headed by "Deleting" and then a rapidly scrolling list of files on his PC that it was deleting.
Boy, was the HoS distraught. All his hard work (and some sus downloads) were not only disappearing before his very eyes but eyes other than his were able to see some of the product of his after hours "work"
Many different keystrokes later, none of which failed to halt this desecration, he asked "but it's OK, though, isn't it, because it's all backed up" and the Tec manager said he hoped so, but sometimes when users tinkered with their PCs they upset the delicate link between PC, server and back-up
Finally, it came to light that the Tech Support Mgr had installed a simple script that just listed all the files on the HoS PC so nothing was deleted.
It did stop the HoS from tinkering though and after hours dalliances came to an end........for a while
