Windows 10: How to reblock an app or process in Controlled Folder Access

Hello, there was an app that Windows Defender blocked from accessing my protected memory. I allowed it and I am asking if I can block it again? There isn't an option for that.

Controlled Folder Access

Hi.

I've been using Controlled Folder Access recently but I'm having a problem getting one application to change/create files. I use doPDF8 to create PDF files, but when CFA is active, it won't save my work. The notice explaining that something has tried accessing the folder only comes up once. (I assume that if you don't do anything about it, the program trying to access the file is put on the 'black list'.) Turning CFA off and then on again causes the notice to appear once more. However, the notice seems to suggest that it is C:\Windows\splwow64.exe that is trying to access/create the file, but when I put this into the 'allow app control' list, it still doesn't work. The only way I can find to get the PDF file created is to turn off CFA, create the file and then turn it back on again.

Any ideas?

Matt

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?

 

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:
