Windows 10: Controlled Folder Access did not block writes to a controlled folder. Why?

Background: Controlled folder access is enabled on my Windows 11 Education computer. OneDrive is set to backup C:\Users\MYNAME\Documents. So my documents are in C:\Users\MYNAME\OneDrive\Documents, and my c:\Users]\MYNAME\Documents folder is always empty. The C:\Users\MYNAME\OneDrive\Documents is listed in "Protected Folders" as being protected.Yesterday, I installed R, RStudio and RTools on my Windows 11 Pro computer. None of the three was given permission to write to controlled folders. To be sure, I checked. None of the three is listed in "Allow an app through Controlled folder access

:)

 

Controlled Folder Access blocked

Hi Aeolus0,

The Controlled Folder Access is an enterprise-class ransomware protection component that was recently added to Windows Defender. When you turn on Controlled folder access, a lot of the folders you use most often will be protected by default. This means that
content in any of these folders cannot be accessed or changed by any unknown or untrusted apps. Once you add additional folders, they become automatically protected as well. To add protected folders:

• Select Virus & threat protection settings.
• Under Controlled folder access, select Protected folders.
• Select Add a protected folder and follow the prompts to add folders.

If you see an App is blocked message when you try to use a familiar app, you can simply unblock the app. If this message displays:

• Write down or take note of the path of the blocked app.
• Select the message, and then select Add an allowed app.
• Browse for the program you want to allow access.

As for your query about having no sounds on your computer, it could be caused by an outdated or corrupted audio driver. For us to assist you better, kindly answer the questions below:

Windows Security - Controlled Folder Access - Recently Blocked App List

Hello,

I thank you for your response. I know how to add and remove apps to and from the controlled folder access. My question is how to remove an app from the "Recently Blocked Apps" list. In Windows 1809 they made it easier to add apps to the controlled folder
access without having to navigate to the exe. They added a Recently Blocked Apps list you can select from. The steps for Windows 1809 are:

1. Open the Windows Security and click/tap on the Virus & threat protection icon.

2. Click/tap on the Manage ransomware protection link under the Ransomware protection section.

3. Click/tap on the Allow an app through Controlled folder access link.

4. Click/tap on Yes when prompted by UAC to approve.

5. Click/tap on Add an Allowed App (+) sign

6. Click or tap Recently Blocked Apps from the drop down menu. (NEW)

7. Click or tap on the (+) button for the app you want to add from the list. (NEW)

It is this Recently Blocked Folders List I am trying to edit to remove apps I have not authorized and that have been deleted from my PC and are still in this list. I know you can select an allowed app from the controlled folder access list and you will
see a REMOVE button, which in 1809 will put the app back in the Recently Blocked Apps list if it was there originally. But that same process does not work on the Blocked Apps list.

My question still remains:

How do you delete an app from the "Recently Blocked Apps" list in Windows Security for Windows 1809?
