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:


explorer key in registry editor


Step 3

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





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!

    I did this in mi PC and it worked perfectly, then I tried to do it on other PCs and I cannot find the “explorer” key under the “policies” key, why can this be happening?

    This HowTo was written perfectly! Detailed on each and every step and worked like a charm. I’m glad that I stumbled upon it. Now my forced-update headache, cftmon.exe, has gone away.
