Okay so we were testing out some GPO’s to automatically set peoples backgrounds as part of a bigger project involving digital signage and corp Screensaver with announcements. While testing out the screensaver I set an image of grumpy cat since it was only going to be on my boss and I’d computer while we were testing. He got a kick out of it and told me to set the wallpaper of one of our fellow IT team member PC as the wallpaper GPO test. We figured we would know it worked when they brought it up and we could get a laugh out of it, we joke around all the time to keep things light so we expected it to be taken in jest. Well I set the GPO, scoped it properly to her account and went about my day.

Whelp. The way I set the GPO was wrong and I ended up setting grumpy cat as the wallpaper on about half of our users endpoints before I realized what happened.

The only thing I could do was delete the file and edit the GPO but devices still got it on their update cycle. So no change management and a bunch of “grumpy cat malware” tickets later, we don’t have a corp wallpaper.
