Windows keyboard unlock issue

Could you please clarify how "WE" are connecting to ONE computer?  Normally only one person can use one computer at one time. Certainly for RDP that is true. Some Remote Control apps (LogMeIn and so on) allow the user to grab control.

So clarify please. It looks possibly like A is locking out B trying to grab the keyboard.

Hi John,

Sorry make you confuse. I mean that my friend use his home computer and I use my home computer. We often happen this situation. When we left our computers, we lock it. When we come back, unlock it.

Thank you for clarifying.

What is "Computer only / Duplicate / Extend / Projector Only", and can you try an experiment with only the computer monitor, one keyboard, and one mouse connected.

If that still fails,

1. Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete and restart.
2. Check thoroughly for viruses and malware.

Also, we have many Windows 7 machines at clients and this (above) does not happen.

Since both you and your friend are affected the same way, look for viruses or other software you installed that is causing this.

Hello John.

As far as I am familiar with the topic, in WIndows, when you press Windows logo key+P combination it will show the options to choose a presentation display mode, like you have mentioned. Shift+P does not have a linked key combination and should in no situation react in such way.

Is the keyboard functioning properly? Maybe there is an issue with the keyboard, which is causing the issue when pressing the keys?

I suggest trying with a different keyboard, and using SHIFT+P to test it out, and see if the issue persists.

Your Windows Key is stuck

I thought of that, but two different computers in two different locations are behaving the same way.

Gotcha

Perhaps it's a fat finger of SHIFT+WINDOWS KEY+P.  The Windows Key on my keyboard overlaps the left shift key.  If I hit SHIFT+WINDOWS KEY+P, I get the option to choose a presentation display mode.
