Fix problems that block programs from being installed or removed

Note: Use these steps for Windows programs. If you’re having problems with an app you got from Microsoft Store, go to Fix problems with apps from Microsoft Store.

The Program Install and Uninstall troubleshooter helps you automatically repair issues when you’re blocked from installing or removing programs. It also fixes corrupted registry keys.

First, you’ll need to download the troubleshooter.

If you see the File Download box when you start downloading, select Run or Open.

The troubleshooter provides steps for you to follow. If a program isn’t listed in the uninstall options, you’ll be asked for that program’s product code. To access the code, you’ll need a tool for reading MSI files—which is typically available to IT professionals. You’ll find the product code in the property table of the MSI file.

What it fixes

The troubleshooter helps fix problems that:

Corrupt registry keys on 64-bit operating systems.

Corrupt registry keys that control the update data.

Prevent new programs from being installed.

Prevent existing programs from being completely uninstalled or updated.

Block you from uninstalling a program through Add or Remove Programs (or Programs and Features) in Control Panel.

If you’re trying to remove malware, you can use Windows Security (or another antivirus tool), or you can use the Windows Malicious Software Removal tool.

Prevent Users From Running Certain Programs

By Mitch Bartlett 16 Comments

If you’re a system administrator, you may have problems with your users running programs like iTunes or BitTorrent in your Microsoft Windows environment? If you want to stop such programs from running, here’s how to use Group Policy or the Registry to prevent users from running certain programs.

Option 1 – Apply Group Policy

1. Hold down the Windows Key and press “R” to bring up the Run dialog box.
2. Type “gpedit.msc“, then press “Enter“. The Group Policy Editor appears.
3. Expand “User Configuration” > “Administrative Templates“, then select “System“.
4. Open the policy “Don’t run specified Windows applications“.
   
5. Set the policy to “Enabled“, then select “Show…”
   
6. Add the programs you would like to prevent the user from running to the List of disallowed applications. Use the name of the application launching file such as “itunes.exe“, “bittorent.exe“, etc.
   

Option 2 – Apply Via Registry

1. Hold down the Windows Key and press “R” to bring up the Run dialog box.
2. Type “regedit“, then press “Enter“. The Registry Editor appears.
3. Expand the following:
   • HKEY_CURRENT_USER
   • SOFTWARE
   • Microsoft
   • Windows
   • CurrentVersion
   • Policies
   • Explorer
4. Right-click a blank area on the right side and add a new “DWORD (32-bit) Value” named “DisallowRun“.
5. Open “DisallowRun” and give it a Value of “1“.
6. Right-click and add a new “Key“, also named “DisallowRun“. The folder is then created.
   
7. Select the “DisallowRun” folder on the left pane.
8. Right-click a blank area on the right side and add a new “DWORD (32-bit) Value” named “1“.
9. Open “1” and give it a Value with the application you would like to block, like “itunes.exe“.
10. Repeat steps 8 and 9 with any additional applications you wish to block, only increase the number used in the “DWORD (32-bit) Value” each time (2, 3, 4 ,5, etc)

So if I wanted to block two applications, “itunes.exe” and “bittorrent.exe“, my Registry Editor would look like this…

From now on the user will get a message “This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.” when he tries to run the programs you added.

I should mention that if the user is smart enough to rename the program file, they will be able to run the program again.

If this tutorial does not meet your needs, you might be able to use Applocker for your needs. Using Applocker allows you to deny access to applications based on publisher, path, or file hash. See more info about Applocker at Microsoft Technet.

Block or Unblock Programs in Windows Defender Firewall

By Mitch Bartlett 15 Comments

In Microsoft Windows 10 you can set the Windows Defender Firewall to block or unblock certain applications. Here’s how.

1. Select the “Start” button, then type “firewall“.
2. Select the “Windows Defender Firewall” option.
3. Choose the “Allow an app or feature through Windows Defender Firewall” option in the left pane.
   
4. Unchecking the box to the left of the application name disallows it from accessing network resources, while checking it allows access. You can also check the boxes to the right of the name labeled “Private” or “Public” to allow and disallow the app on private or public networks respectively.
   
5. If the program you wish to block or unblock is not listed, you can click the “Allow another app…” button to add it. Choose the application in the list and select “Add“. If the program is not in this list, use the “Browse…” button to select the program file manually.

No…I am definitely not a pro…so a little more explanation would be great…say, what about gallery or settings….?

Susan Olon says

Could you give me an example as to what applications should NOT cross the firewall??

Any application can block any crack microsoft office .. can you help me how to block any crack microsoft on my laptop ..

Richard Jordan says

The firewall is blocking access to open areas of the United Nations website. Even public press releases. How do I uninstall Micrsoft Edge, if that is what is blocking me.

So, what’s the meaning of a checked box and an unchecked box?
I am trying to allow zoom to have access but firewall is blocking it.

I’m trying to block Microsoft family features so it won’t send me the annoying pop-ups about signing in.

I’m on the correct thing but I can’t uncheck the box beside it. If I click the box it does nothing,

Do we have any registry settings for the same.

Thanks, it worked

What if when you click “Allow another app” and then Choose the app in the directory and it gives an error about a possible virus?

Josh Everett says

Is there any way to do this without Administrator rights?

Settings for some pro, doesn’t change!
its somehow locked, as if a registry rule is overriding this windows rules.

Richard S Nye says

I have been trying for hours to Block “Fortnite” from my PC windows 10

Edwin Wetzel says

nothing helps. i’ve been trying to hook up my wifi scanner and i’ve been doing this for hours without any success. i’ve followed all the different procedures on line including going into the defender advanced settings and allowing file and printer sharing rules and still does not work.

What if you cant click the “Allow the app or feature through windows defender firewall”?

Mike Bading says

Mitch,
First, I hope this note finds all well with you and yours.
Second, thank you for your effort here.
Third, my question(s):
What do you do when Windows Defender keeps resetting Microsoft Apps you have unchecked/deselected in Windows 10 Home or Windows 10 Pro?
Example: Let’s say I wish to block Cortana (or any other app). I then follow your instructions here and uncheck/deselect all the boxes pertaining to Cortana and then close the window.
Let’s say, that for whatever reason(s), I return to the window in your example only to find that Windows has reset/unblocked Cortana without notice and without my permission. This would happen all the time in Win10Home; and I would like to know if this would happen in Win10Pro and what to do about it if it does.

Respectfully,
Mike Bading
