Solved Increasingly aggressive Smart App Control

Over the past week or so I find more and more apps being blocked by Smart App Control (Win11 Pro 25H2). I'll post a screen shot of the two most recent ones from today. I ran a winget update which updated ImageGlass and now it's blocked.

It seems unwise to turn off Smart App Control, but it's getting seriously annoying to not be able to use apps I want, like ImageGlass. Or, is it okay/safe to turn off Smart App Control?



(One that I forgot to screenshot said something about not being able to confirm who published a Windows SDK.)

winver:


[edited to add:] The C:\Program Files\ImageGlass\Microsoft.Extensions.Configuration.Abstractions.dll file about which Windows Security squawks is dated 11/14/2025, so it appears it wasn't updated by today's winget session, though ImageGlass itself was updated. If that 11/14/2025 .dll file worked just fine this morning with a previous version of the program, why is it now being blocked?

SAC is junk. its safe to disable if you dont like it. smartscreen/defender is enough (if you want the constraints enabled)

I would disable it, also.

Disable it.

To many reasons I don't intend to enable it even though MS confirms we will be able to enable and disable SAC without reinstalling windows soon. Microsoft Smart App Control (SAC) can slow down apps and installations, especially on older systems or with less common apps, as it constantly analyzes apps in the background, causing launch delays, longer installs, and sometimes blocking safe software due to its AI-driven security. While Microsoft claims it can improve performance by preventing malware from running, many users find it intrusive and report slowdowns, often disabling it for better responsiveness.

Thanks, guys. I'm going to disable it. The straw? It's blocking my VPN software:

What's old is new again. Those of us waiting to be young again will remember the dirty tricks Microsoft played to keep competing programs from installing in Windows...this goes back to the early 1990s!

Disabled it on my Geekom PC. It blocked me from mounting a Windows 11 direct download iso from Microsoft. That was the final straw. No issue mounting an iso that was created using the MCT. Microsoft is blocking its own apps? That is insanity.

The reason to leave it disabled is it has no whitelist to allow you to override false positives and to prevent drivers and services from being blocked.

You have granular control with AppLocker. SAC is more trouble than its worth.
