Am pissed yesterday to have to spend a hour to disable a global shortcut key in Windows, caused by a pre-installed software from HP.
If you bought your PC from HP/Compaq, then when you press 【Ctrl+Alt+s】, it'll pop up the HP Support Information window. (also, 【Ctrl+Alt+h】 pops up the PC Doctor software.)
This is a pain in the ass, because 【Ctrl+Alt+s】 is used in Second Life virtual world software, Blender 3D Modeling Software, Emacs, all i use daily. All these 3 are major software, with extensive keyboard shortcuts.
So, how do you disable it?
Open your Start menu, and look for the folder named “PC Help & Tools”, right click the “HP support information”, then chose Properties.
Click on the Shortcut tab, then the Shortcut key field, then just delete it there.
You can also find the file directly at
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\PC Help & Tools.
