I couldn't find this anywhere on the internet, for some reason windows wont let me type Shift+F. I tried turning on caps lock and pressing Shift+F, still nothing. I know this is not hardware because I tried it with multiple keyboards. I closed everything that my computer let me close, but nothing. It's probably a windows option. Does anyone know what this could be? (I think its something to do with the Control panel) running windows 7

This question is repeating for various hotkeys here on the SuperUser. One of the easiest ways to rule out the problem is to prepare your computer for restart and then start killing applications and processes, starting with most likely ones. After each kill, check whether the shortcut is still taken. This way you will determine which application/process caused the problem.

Please see this Q/A and case similar to yours.

EDIT:
You can use Process Explorer to get real overview of all processes. It will perhaps show more than you were able to see. Then you also can start stopping the services.

A. stop non-Microsoft processes

  1. Run Processs Explorer.

  2. menu View > Show processes from all users ← check this item if it is not checked.

  3. menu View > Select columns...: on Process Image tab check Company Name.

    Now concentrate on all the software which is not from the Microsoft. Most likely the software from the Microsoft is not causing the problem. Observe column Company Name in the table, so you can quickly recognize non-Microsoft processes and kill them all.

B. stop non-Microsoft services

  1. Open Windows Services console
  2. Stop every service which has path different than C:\Windows – you can see the path when you open properties of each service.

Remeber to test the keyboard shortcut after each termination.

Global hotkeys can be registered by any application on Windows. So most probably an application has taken this shortcut.

On Windows 7 it seems to be safe to use Windows Hotkey Explorer to see which one it is.
