Prepare for security updates

To confirm Microsoft's security updates are compatible with your environment, Microsoft needs a registry key from your antivirus. To allow Microsoft's security updates on your endpoints, see the instructions for your product.


Apply Windows Action Center settings in Malwarebytes Endpoint Protection

Register your endpoints with the Windows Action Center, then install the latest Malwarebytes for Windows updates on your endpoints.


Your endpoints must have at least Malwarebytes for Windows v3.1.8.1830, database update v1.0.3624.


  1. Log in to your Malwarebytes cloud account.

  2. Click Settings > Policies.

  3. Click any policy.

  4. Click Endpoint Protection, then scroll down to Windows Action Center.

  5. Click Let Malwarebytes apply the best Windows Action Center settings based on your system (recommended).

  6. Repeat steps 3 - 5 for each additional policy you want to register with the Windows Action Center.

  7. Click the Endpoints tab.

  8. Click the checkboxes to select endpoints you wish to update.

  9. Click Actions > Check for Protection Updates.


Install security updates

Install the latest security updates from Microsoft on each endpoint. Your endpoints can check for updates automatically using your Group Policy or registry. Refer to Microsoft's article How to configure automatic updates by using Group Policy or registry settings.
