I have a touch screen computer with Windows 7 and I would like to disable the multi-touch gesture :
How to disable "multi-touch gestures and inking"
Run \Windows\System32\regedt32 as Administrator
Navigate to HKEY_USERS
Find entry that starts with S-1-5-21-xxxxxxxx
Note there might be a few GUIDS that starts with S-1-5-21. You need the one that you can drill to S-1-5-21xx\Software\Microsoft\Wisp
Under Wisp key there should be keys like Pen, Touch, to indicate you are in the right location
Under Wisp key add additional key MultiTouch
Go inside MultiTouch key and create DWORD MultiTouchEnabled set to 0
Reboot
