In Windows 7, when I have multiple monitors extending my desktop, there is functionality to activate a certain monitor by pressing Ctrl+[monitor #]. So if I press Ctrl+2, then the current program jumps over to the monitor identified as monitor 2. I'm sure this functionality serves a good purpose, but it can be rather annoying in programs that rely on Ctrl + [number] for other functionality.

Is there a way to disable this feature in Windows?

    [Ctrl]+[Number] as described is not not a Windows feature. Do you have any third party applications that may have assigned this hotkey? Perhaps graphics driver or display managing software?

  • Correct. By default, in Windows, you can move open windows across monitors using the Snap functionality, as described here: 7tutorials.com/… You must have something installed that allows you to do what you described. Uninstalling it will "fix" your "issue".

    Please see How can I determine which process owns a hotkey in Windows? to find out what's causing this behaviour. You can add your own answer with what it turned out to be.

Found the Super Utilities running in my notification area. It’s the Multi-Display Control Panel utility where you can set the “Hotkey to move Window between Display”.

I simply reassigned the hotkeys for now.

  • Thank you so much this was doing my nut in, as ctrl-1 is the keyboard short cut for auto fix in Eclipse...

  • @Malachi Right-click on the "Super Utility" icon in your system tray, select "Multi-Display Control Panel", click Disable.

Thanks for point me in the right direction, user137553.

Reassigning the keys didn't fix it for me, but I found that the MCTDUtil process was responsible for Super Utilities, and when I killed in via Process Explorer the problem when away.

I used CCleaner to disable MCTDUtil from getting launched at Startup, and my CTRL + 1 and CTRL + 2 hotkeys are working correctly now in Outlook and Firefox!

This "utility" was switching my screens when I hit the hot keys, whether or not I was also holding down CTRL or ALT or SHIFT.

I couldn't find any way to directly uninstall it, but located the file responsible in this directory: C:\Program Files (x86)\Common Files\DesktopUtil

I changed the name of the DesktopUtil folder to _old_DesktopUtil and now Super Utility no longer runs at startup. Headache solved.
