Regardless of whether you choose Microsoft Defender Antivirus, or a third party antivirus solution you need to be sure these products are not scanning critical File and folders because Occasionally Microsoft Security Essentials or Microsoft Defender cause problems with some Files and folders. Typical issues include slow performance , deleting some necessary files or erratic operation or it may flag a file or folder that you trust as malicious. To work around these problems you can add this kind of files and folders to the list of exceptions.
What is new: (Thursday, 09. September 2021)
1. [Fixed] – Defender Exclusion Tool Doesn’t work on Windows 11
2. [Added] – Some code improvements
In Windows 10 , there is a new app called Microsoft Defender Security Center . The app, formerly known as “Microsoft Defender Dashboard”, has been created to help the user control his security and privacy settings. You can add any trusted file, file type, folder, or a process to the exclusions list with the following steps ;
1. Open settings Application
2. Choose Update & security
3. Open Windows security
4. Select Virus & threat protection
5. Click Manage settings under the Virus & threat protection settings
6. Click Add or remove exclusions
7. Under Add an exclusion, select the files, folders, file types, or process.
You may need to repeat the instructions to exclude other items you don’t want the antivirus to scan to avoid false positives
As you see adding exceptions manually through the graphical user interface would be time consuming, tedious and, prone to human error therefore we have coded a portable Freeware to simplify the whole process.

We have restricted command line support for security reasons. You can add files and folders via the right click menu (under the Options menu).We have noted down your request
I tried to use this nice tool via command line but it seems not to accept parameters. I also tried to create an exclusion list and load it by drag and drop but it seems not working.
Is there a way to reduce GUI operations to the minimum steps ? I’m looking for a way to avoid WD mess on my bat scripts without having to disinstall it. Yesterday I had some bat files deleted and luckily I had backups, but they were not even quarantined !
Thanks and have a nice day, V.
very useful to me
There is no cmd parameter support for security reasons.
Defender Exclusion Tool v1.3
Why not support CMD Parameter ?
Where is the download button for Defender Exclusions?
Trillon thx for your (always) fast answer! So i’ll try to get an older version of MSE, would be terrific to use your DET in MSE. I’ll tell’ya later.
Hi, We installed Microsoft Security Essentials on win7 pro for testign purpose, but it gives an error while updating! That’s why we couldn’t test it in the final version. But it was working in older versions.
Hi Masters. I’ve been reading in many sites that this excellent tool works also for Microsoft Security Essentials, which i use a lot in Windows Seven for very modest & old machines, but… the exclussion list of the Microsoft Security Essentials seems to be absolutely unaffected by Defender Exclusion Tool. It would be terrific a tool like this to help MSE! Thx a lot for your time.
Hello, a good idea would be to add a password function to open the application to protect it from unwanted intervention.
@Meeto, Macrium Reflect is one, SUMo (Software Update Monitor) is another. Pretty sure there are many more. Defender is good, but still has problems and is a bit too disk-intensive for my taste.
@Mee, this is about Defender Exclusion Tool, not Defender Control. The option is only available in MS Defender, that’s why I posted.
@George, also what applications/programs have you noticed caused increased Defender usage? If you could post the list that would be most helpful to all.
@George, where is the process exclusion within Defender Control? I know it’s within Defender (Security Health) but I don’t see it in DC.
