On Windows Security (formerly known as Windows Defender Security Center), Controlled folder access is a feature designed to protect your data against ransomware and other dangerous malware.

When enabled, the anti-malware feature monitors the changes that apps make to your documents, and if suspicious behavior is detected, the app gets blocked automatically. The only caveat is that it’s not perfect, and it’s possible for Controlled folder access to block a trusted application.

To ease this problem, starting with the Windows 10 October 2018 Update (version 1809), the feature has updated with a new option to quickly allow recently blocked applications without the need to disable the security feature just because of a false positive.

In this Windows 10 guide, we’ll walk you through the easy steps to whitelist app that you trust and were recently blocked by Controlled folder access with the new option available with the October 2018 Update.

How to allow blocked apps by the Windows 10’s ransomware protection

To allow apps that were recently blocked by Controlled folder access on Windows Security, use these steps:

  1. Open Windows Security.
  2. Click on Virus & threat protection.
  3. Under “Ransomware protection,” click the Manage ransomware protection option.

  4. Click the Allow an app through Controlled folder access option.

  5. Click the Add an allowed app button.
  6. Click the Recently blocked apps option.

  7. Click the + (plus) button for the app you trust and want to allow.

  8. Click the Close button.

Once you’ve completed the steps, Controlled folder access will no longer try to block the app you allowed on Windows 10.

If you made a mistake, you can always select the app from the list, and click the Remove button to block it again.
