Oh Paul, that's very clever of you to discover how to turn off the new use of the Print screen key which opens screen capture! But it's even better than the results you describe. At least on my laptop running Windows 11. When I turn off Open Screen Capture, I can indeed get back to the previous function IF I use Windows key with Print Screen key, then it takes a full screenshot of my.... well, full screen ... and lets me know this by momentarily dimming the screen, and also AUTOMATICALLY saves that screenshot to the default Screenshots folder inside the Pictures folder, just like it used to do. I use this method so frequently in doing research or artwork that I actually have stickers on those two keys on my old Win 10 PC, so I can see or even feel those 2 keys at a glance. Now I can put the same two stickers on my Win 11 laptop! btw, the stickers I use, in case anyone wonders, are actually old school reinforcement stickers (the round circles used on 3-hole looseleaf paper to repair or prevent the holes from ripping apart. I don't remove the center of the stickers, so I have full round bright white circles on a black keyboard, they stand out like a sore thumb! Just what I want. lol.)
Thanks so much, Paul for figuring this out :)
