Close apps easily

Closing a Windows 8 app can sometimes be awkward. You have to drag or swipe down from the very top of the screen right to the very bottom - which might be quite some distance - and if you don't quite swipe all the way, the window just reappears and you have to start again.
The solution? Get Windows to close the app without you having to travel quite so far. It works like this.
Launch REGEDIT, browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\Switcher, and create new DWORD values called MouseCloseThreshold and TouchCloseThreshold.
These define how far mouse and touch users will have to drag the app before they can drop and close it. Start by setting each value to the maximum 1000, reboot, and you'll find you can now drop the window maybe only half way down the screen and still have it close correctly, which is much quicker and easier.
You may also be more likely to close apps accidentally, of course. If this happens, reduce the value of the relevant Registry key a little (the minimum value is 1, setting it to 0 prevents that method of closing at all), reboot and try again. Or delete the keys if you have problems with this and would like to restore the default settings.
