A short trick on how to diable the F1 invoked help screen
To disable the help pane, simply rename it's .exe file in the windows system folder.
As suggested on Microsofts TechNet by user Teemo Tang, the simplest solution would be to rename the file HelpPane.exe found in the %SYSTEMROOT% directory to something different.
Using the following commands I was able to successfully prevent the help window from opening: In an administrative command prompt:
cd %SYSTEMROOT% takeown /f HelpPane.exe
By right clicking the HelpPane.exe and selecting Properties -> Security -> Advanced
Select Administrators and check the mark at full control
Back in the console:
ren HelpPane.exe HelpPane.bak
