L key causes screen to blank and Windows log in screen to come up
This is the weirdest thing ever. It doesn't matter what program I am in but when I hit the "L" key on my Logitech Y-R0065 wireless keyboard, the screen blanks and after about 15 seconds, the Windows login screen comes up. All programs running are still running as if nothing happened. Obviously, the "l" key registers on the screen. I've typed most of this message with the copy and paste function instead of typing the letter "l". I ran SFCFix and got no errors. (see below.) So strange!

It sounds like the "L" key on your Logitech keyboard is triggering a shortcut, possibly related to locking the screen (Win + L) or something else tied to that key. Try the following:
Check for custom keyboard shortcuts: Some keyboards have software (like Logitech Options) that may have assigned a function to the "L" key.
Test with another keyboard: See if the same issue occurs with a different keyboard. If not, it's likely a hardware or configuration issue with the current keyboard.
Reset or reinstall keyboard drivers: Uninstall the keyboard in Device Manager and restart your PC to reinstall the drivers.
Let me know if this helps!
