This guide will help you allow or unblock a program or game if your copy of Windows Defender won’t let you run a program, app or game.
We have used a Windows 11 powered device for this guide. You can follow this tutorial for Windows 10 as well. The steps are almost the same on both.

Is There Any Risk If Windows Defender Won’t Let Me Run A Program/App/Game?
Before proceeding, please keep in mind that this process may expose you to viruses, malware, and other security threats. Only allow Windows Defender to run programs and games you have obtained or bought from a trusted source.
Pirated software, games, and other content that appears to be free is actually not free and contains malware, ransomware, adware, and other things. Malware and other things could be used to carry out criminal activities on your device without your knowledge or consent.
The real danger comes from ransomware. Once it gets into your hard drive, it locks your family pictures, videos and other data, and you are demanded to pay ransom money to get a decryption key to unlock your data.
Windows is harmed by pirated games, software, and other things. As a result of installing pirated software or games, your copy of Windows gets corrupted and performs slowly.
Additionally, your PC may refuse to boot the next time you turn it on. Finally, you may encounter a blue screen of death as well.
Windows 8, Windows 10 and Windows 11 come packed with Windows Defender (now called Microsoft Defender) that is effective, frequently and regularly updated.
Windows Defender immediately blocks suspicious behavior and notifies you whenever it finds anything suspicious.
Pirated software and games are not the only ones blocked by Windows Defender. You can also have this problem with legitimate software and games you have bought.

How To Make Windows Defender Or Windows Security Let Run A Blocked Program/App/Game?
You will have to add an “Exclusion” to exclude a software, app or game from being scanned by Windows Defender. After that, Windows Defender will stop blocking that program or game.
To add an exclusion, follow these steps.
Open the Start Menu and type Windows Security.
Open Windows Security from the search results.
Click on Virus & threat protection.
Under Virus & threat protection settings, click on Manage settings.
Scroll down the page until you find the Exclusions section.
Click on Add or remove exclusions.
Click on Add an exclusion.
Now select what you want to exclude. You will see four options: File, Folder, File type, and Process.
For one program or game, select the File option.
Now locate and select the software or game you want to unblock or allow in Windows Defender.
Click on Open.
That is it. Now try to run your program or game again. It should work fine.
If Your Program Has Many Files, Exclude The Whole Folder
Some games and programs have many files in one folder. If you exclude only one file, Windows Defender may block another file from the same folder.
In that case, select the Folder option instead of File, and select the folder where the program or game is installed.
If Windows Defender Already Blocked Or Removed The File, Restore It First
Adding an exclusion does not bring back a file that Windows Defender has already removed.
Open Windows Security.
Click on Virus & threat protection.
Click on Protection history.
Find your program or game in the list.
Click on it and select Restore.
After restoring it, add the exclusion by following the steps above. Otherwise Windows Defender may block it again.
If The “Add An Exclusion” Button Is Greyed Out
This usually means your PC is managed by your work or school, or another antivirus program is in charge of your PC’s security.
If another antivirus is installed, Windows Defender turns itself off, and you will have to add the exclusion in that antivirus program instead.

Is Adding Exclusions In Windows Defender/Windows Security A Permanent Solution?
Adding an exclusion is normally a lasting solution. The exclusion stays in place after you restart your PC. You do not need to repeat the process after every restart.
However, the exclusion can stop working in these cases.
If you uninstall and reinstall the program, or move it to a different folder, the old exclusion will no longer match it. You will have to add the exclusion again.
If you reset Windows Security settings, or reinstall Windows, your exclusions will be removed.
If the program file itself is replaced by a new version in a different location, add the exclusion for the new file.
To remove an exclusion at any time, go back to Add or remove exclusions, click on the exclusion you want to remove, and select Remove.
Frequently Asked Questions
Will Windows Defender block my program again after I add an exclusion?
No, not normally. Once a file or folder is excluded, Windows Defender will skip it during scans. If it gets blocked again, check that you excluded the correct file or folder, and that the file was restored from Protection history first.
Is it safe to add an exclusion?
It is safe only for programs and games you trust and bought from a trusted source. Never add an exclusion for a file you downloaded from an unknown website.
What is the difference between File and Folder exclusion?
File exclusion unblocks one single file. Folder exclusion unblocks every file inside that folder. Folder exclusion is better for games and programs that have many files.
I added an exclusion but my program still won’t open. What should I do?
First, restore the file from Protection history if it was removed. Second, try excluding the whole folder instead of one file. Third, check if Controlled folder access or SmartScreen is blocking it separately — these are different from the antivirus exclusion.
Final Words
Hopefully, the given instructions help you get rid of this annoying situation, if your copy of Windows Defender won’t let you run a program or game.
We highly suggest adding exclusions only for legitimate third-party programs and games.
