How to check if Windows Defender is Blocker an Application

To check if Windows Defender is blocking some functions of an app, follow these steps:

1. Open Windows Defender Security Center
2. Go to the "Virus & threat protection" section
3. Click on "Manage ransomware protection"
4. Check the "Controlled folder access" section

If the app you're trying to run is listed under "Blocked apps and files", Windows Defender is blocking it.

You can also check the Windows Event Viewer to see if Windows Defender has logged any blocking events. To do this, follow these steps:

1. Press Windows key + X and select Event Viewer
2. Go to Windows Logs > Security
3. Look for events with Event ID: 1116

The description of the event will tell you if Windows Defender has blocked a file or process.

If you trust the app and want to allow it to run, you can add it to the list of allowed apps in Windows Defender.
