You may need to click a folder to view the program’s app icon. For example, if you want to block Notepad, you would scroll down and click the “Windows Accessories” folder to reveal the Notepad app icon.

The extension will almost always be “. exe”. For example, if you looked up the file location of Notepad, you’d find that its name is “notepad. exe”.

You’ll want to do this on the user account for the person for whom you want to block this application.

If you aren’t an administrator, you won’t be able to open the Registry Editor.

Double-click the “HKEY_CURRENT_USER” folder in the top-left side of the window. Double-click the “Software” folder below “HKEY_CURRENT_USER”. Double-click the “Microsoft” folder. Double-click the “Windows” folder. Double-click the “CurrentVersion” folder.

If there isn’t an “Explorer” folder, you’ll need to create one.

The menus in the upper-left side of the window apply to whichever folder is open at the time.

For example, to block Notepad, you would type in notepad. exe here.

If you want to add subsequent string values for other programs, name them in numerical order (e. g. , “2”, “3”, “4”, etc. ).
