Windows 10: Why does Controlled Folder Access block known Microsoft executables?

Hello all


I use Controlled Folder Access (CFA), and every so often I get a notification telling me that a Microsoft program has been blocked from making changes to memory. I am very happy with CFA, and I'm very able to add and remove programs from the "allowed" list. That is not my question.


My question is: why are known Microsoft executables (which are part of Windows 10) being blocked? Surely CFA should know about Windows 10's own executables.


My usual response to this is just ignore it; everything carries on fine when I ignore it. In the screenshot below WmiPrvSE.exe is being blocked, and that's part of Windows 10 itself. This has happened a few times a day for the last week or so. I'm ignoring the notifications and I expect them to go away eventually. And I expect to get notifications later about some other Windows 10 executable being blocked.


Another obvious question is: Can I do anything to "refresh" CFA's knowledge about which executables are legitimate Windows 10 programs. I don't want to add all these programs to the "allowed" list. I just think CFA ought to know which executables are part of Windows 10 and are allowed, and that maybe I ought to be able to "remind" it.


So in summary:

• Why are Windows 10's own executables being blocked by CFA?
• Can I do anything to "remind" CFA about what it should know already?

Many thanks.

How do I find the application executable that is blocked by Control Folder Access.

I turned on Control Folder Access. When I run a application that is not trusted I get a notification that shows an abbreviated path due to notification length restrictions. I save it to view it under Notifications it is still not readable. I click on it
to expand the message and it goes away. I have tried going to the "Allow an app through Controlled folder". Instead of showing a list of apps it displays File Manager expecting me to find the executable. Since I cannot read the path or executable in the notification
I cannot add the app to the list of allowed apps.

Is there a log that displays the entire notification?

Is there a log of app names blocked?

Suggestions:

1. If you are going to use notifications to advise an app is blocked display the executable only. That way I can search for the executable.

2, Give the option of accepting/denying the app access in the Notification.

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:

• Have you made any changes to your computer prior to this issue?
• What troubleshooting steps have you done so far?
• Which version and OS build number of Windows 10 is currently installed? To check, press the
  Windows key, type winver, and press the
  Enter key.
• Have you tried to download and install the latest audio driver from the manufacturer's website of your device?

Meanwhile, you can try the steps in this
