Computer users familiar with Windows operating systems are usually quite familiar with the F1 keyboard shortcut to reach the Windows Help and Support Center. While the shortcut can be a convenient feature for those that utilize this resource frequently, it can be annoying for more experienced users as an accidental touch of the key will cause a sometimes significant delay as the site loads and then has to be closed. If you have no need for the F1 key as a shortcut to Help, you can disable it.
Click on the "Start" button on your Windows desktop.
Click on "Run," and then type "regedit" into the Run text box. Do not type in the quotation marks. The Registry Editor will open.
Go to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\HELPCTR.EXE .
Double-click on "(Default)." Change the value so that it reads "C:\Windows\svchost.exe" (again, without the quotation marks).
Click "OK." Close the Registry Editor. Restart your operating system, and you will have successfully disabled the F1 key shortcut.
