In theory you can use your mouse to perform whatever task is being shown, but for me that has proven problematic - partly because I'm running Windows inside a VM I guess.
To kill these there are a couple of things you can do:
- Disable the touchscreen device in the device manager. If you don't have one, it's useless anyway. Just open up the device manager, find the touch-screen, right click on it, and select "disable". Why does Windows add a touch-screen device when there isn't one? Who knows.
- Run a command prompt as administrator, then execute the following command:
reg add HKCU\Software\Policies\Microsoft\Windows\EdgeUI /v DisableHelpStick /t reg_dword /d 1 /f
That's all there is to it. Simple fix, but there's no way I'd remember it next time I rebuild.
