Print Screen key doesn't work on my Windows 11

Had the same problem and tried for hours to screen shot and send to paint. This way , FN+windows +print screen worked...

No print screen app will work on Win11. I've tried LightShow, ShareX, Greenshot j(the latter I have used for years on my Win10Home laptop), have spent an hour on the phone with a Win11 Tech support officer who was VERY helpful and thorough, and also spent an hour on the phone with a Lenovo Yoga expert who was also very helpful and thorough and neither of them could get any screen snipping program working on my laptop. The problem seems to be with the PrtSc key - no matter what they did it wouldn't work. We've edited via Regedit and reassigned the PrtSc key in the settings for each of the above-mentioned apps and that didn't work either. Win11 is buggy. I'm sorry I bought a new laptop.

I'm still working with them

What functionality is used by pressing Win+Shift+S? Is it this that is preventing any other app from working? How can this be disabled please? Is this it?

I just came across this article where everything I did it would just capture both monitors and even the alt + prt scn would not work. For me it was because I has Logi+ Options installed it overrode the windows settings so even though I had use print screen key to open screen capture on it would not work.

Going into Logi+ Options and and changing the print screen to just print screen fixed it for me.

I tried that option. The PrtSc key still does nothing. It appears as though Microsoft has rendered the key inoperable.
