Install KB5004300 Update from Microsoft

Microsoft released an update at the start of August 2021 to fix this bug, and you should install the Cumulative Update KB5004300 for Windows 11 (10.0.22000.100).

Follow these steps:

Step 1: Press Win I to open Windows 11 Settings. Then, click Windows Update from the left-hand menu.

Alternatively, press Win R, type ms-settings:windowsupdate, and click OK to open Windows Update.

Step 2: Click Check for updates. If Windows finds any available updates, including KB5004300, it will download and install them.

Step 3: You will be prompted to restart the PC to complete the installation.

If you prefer not to install the Windows 11 update, consider trying other methods to resolve your issue.

Adjust Registry Keys

You can create a Spynet Registry key if automatic sample submission turns off after every startup. This ensures the functionality of this component of Windows Defender remains active between restarts.

Note: This fix applies only to Windows 11 builds older than 10.0.22000.100.

Here’s how to perform this task:

Step 1: Type regedit into the search bar and click the result to open Registry Editor.

Step 2: Navigate to this path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender.

Step 3: Right-click Windows Defender and choose New > Key.

Step 4: Rename the new key to SpyNet.

Step 5: Go to the SpyNet folder, right-click a blank space, and select New DWORD (32-bit) Value. Name the new key DisableBlockAtFirstSeen.

Step 6: Double-click it, set Base to Hexadecimal, and enter a value data of 0.

Step 7: Also, create keys named SpynetReporting and SubmitSamplesConsent. Set Base to Hexadecimal and the value data to 1 for these two keys.

Step 8: Restart your PC and see if your issue is resolved.

Modify Your Group Policy

The Group Policy Editor is unavailable for Windows 11 Home, so try this method in Pro or higher editions.

Step 1: Press Win R, type gpedit.msc, and click OK.

Step 2: Go to Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus > MAPS.

Step 3: On the right side, locate Send file samples when further analysis is required.

Step 4: Double-click it and select Enabled.

Step 5: Save the changes and restart the PC.
