Remove the “Properties” Option from My Computer

Use this hack to hide the System Properties screen and remove the Properties option from My Computer. Useful if you don’t want anyone messing around with, well, Your Computer.

Navigate to:
HCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer

And to:
HLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer

Set the DWORD Value NoPropertiesMyComputer to 1 to hide the Properties option. Reset it to 0 to re- enable what you disabled.

Restart or log off and back on for the change to take effect.
