"Remove Windows Defender and connected Windows Security Components" Option cause Microsoft Store third party apps can't uninstall

"Remove Windows Defender and connected Windows Security Components" Option cause Microsoft Store third party apps can't uninstall, only Microsoft built in store apps can normally uninstall. Both windows 10 & 11 have this issue. After remove Windows Defender and connected Windows Security Components , system restore can't recover removed security Components , update machine can't fix security Components. Need reset PC, only disable Windows Defender Antivirus, uninstall Store apps is back normal

Thanks for writing..
Can you say what version of Windows and kind of you updates which you have installed. In Windows 11 uninstalling apps is working fine. Its helps me to provide a fix for that.

[chuck00000]

I said both Windows 10 & Windows 11 has this issue. I'm using Windows 11 latest Dev build 25295;

I tested on Windows 10, same issue

[ionuttbara]

i didn't see the issue. so in lastest insider builds the issue is not present.. but I will not close this issue, now

[ionuttbara]

in lastest version of script, this does not affect the application uninstalling in Windows 11 and even in 10.

[ionuttbara]

re-opening the issue, because its happen in 12.0 and 12.5 beta! on Windows 11 22H2 Moment 2 and Windows 10 20H2. I'll investigate and work with fixes!

[chuck00000]

Also, all apps from Microsoft Store cannot be updated because of this.

I am having an issue Re-Enabling Defender and Components as well. My Windows Security App is coming up Black and this happened after I used the Script to Disable Windows Defender and Security components.

Now when I tried to re-enable it because I was getting a lot of errors in Windows Events I get the error ERROR: The process "Smartscreen.exe" not found. The system cannot find the file specified.

I don't know what to do, I have tried so many fixes from online but nothing works, and I really don't want to re-install windows.

Unable to start a DCOM Server: {A463FCB9-6B1C-4E0D-A80B-A2CA7999E25D} as Unavailable/Unavailable. The error:
"2147942402"
Happened while starting this command:
C:\Windows\System32\smartscreen.exe -Embedding

[ionuttbara]

so maybe is caused by removal of the smartscreen.. so i will check.. i'll put in 12.1, because i want to re-organize the code..

[ionuttbara]

the script is unregistering the classes of the smartscreen , by removing the following registry values

[-HKEY_CLASSES_ROOT\WOW6432Node\CLSID{a463fcb9-6b1c-4e0d-a80b-a2ca7999e25d}]

[-HKEY_CLASSES_ROOT\CLSID{a463fcb9-6b1c-4e0d-a80b-a2ca7999e25d}]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID{a463fcb9-6b1c-4e0d-a80b-a2ca7999e25d}]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID{a463fcb9-6b1c-4e0d-a80b-a2ca7999e25d}]

so restoring them it will fix the issue.

[ionuttbara]

i'll provide a reg file which is adding that values back into windows later today. So it will apply with PowerRun, and reboot. This is will be the solution of this issue.

Thank you!

Hi Jbara, Just wondering if this reg file is ready yet?

[XBadFellaX]

@jbara2002 please help on how to restore these registry entries, would really appreciate it.

[ionuttbara]

Save into registry file and reboot the pc.
