Do you want to stop applications or .EXE programs from running on your computer? Applications and .EXE files can be individually disabled from within the Registry Editor on any Windows computer. But be careful when editing the registry. Changing or deleting any values not explicitly covered in this article can cause damage to your computer. This wikiHow article teaches you how to prevent an application from running on a Windows computer.
Things You Should Know
- You can block a program name from running on your Windows PC by creating a DisallowRun registry value.
- You'll need the program file name of the application you want to block, such as notepad.exe or handbrake.exe .
- Users will not be able to double-click the file or select it from the Start menu to run it, but they can change its name to bypass the limitation.
Steps
-
Open the Start menu . Click the Windows logo in the bottom-left corner of the screen.
-
Find the program you want to block. You may need to click All Apps to expand the list.Advertisement
-
Right-click the program and select More . Another menu will expand.
-
Click Open file location . This opens the file location of the program's shortcut in File Explorer.
-
Right-click the shortcut and select Open file location . This opens the program's actual file location.
-
Right-click the program's icon and select Properties . Doing so opens the Properties window for the program.
-
Review the application's name and extension. The file's name is listed in the text box at the top of the Properties window, while the extension is in parentheses to the right of the "Type of file" heading. You'll combine these two (e.g., "name.extension") to create the file's name in the Registry Editor.
- 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".
