Do you have a program on your computer that you would like Windows to block from opening?  With a few tweaks to the Windows 7 registry, you can force it to prevent nearly any program of your choice from opening, and the process is entirely reversible!  

How To Disallow Programs From Running In Windows 7


Step 1

Hold down the Windows Key and Press R to open the run dialog.  In here Type regedit and then Press Enter.


Step 2

Browse to the following registry key: HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer


Step 3

Right-Click in the right pane of the Explorer key and Select New > DWORD (32-bit) Value. Rename the new DWORD to: DisallowRun  


Step 4

Right-Click the DisallowRun DWORD you just created and Select Modify.* Set the Value data to 1 and then Click OK. *You can also just Double-Click the DisallowRun DWORD to modify it.  

Step 5

Déjà vu!  We’re going to create another DisallowRun, but this time it is going to be a registry key.  Right-Click the Explorer key and then Select New > Key and name it DisallowRun.


Step 6

In the new DisallowRun key you just created, Right-Click in the right pane and Select New > String Value.  Name the new String anything you like, but for organizational purposes, it would be a good idea to call it something in reference to the program you want to block.


Step 7

Modify the new String and for the value data Type in the process name.  In my example, I’m going to block Internet Explorer, so I will disallow iexplore.exe from running.  No need to include the full file path, just the name of the .exe file will do.  

Step 8

Restart your computer for changes to take effect.


Now the designated programs should no longer open while you are using Windows 7!  Groovy! Thanks! Comment
