UWP-based Apps broke after removed Windows Security

[unknowtherwise67]

Photo and other UWP-related app doesn't work anymore after remove Security from Windows, applied hotfix1_uwp. exe DOES NOT fix the issues either.

i'm looking deeper for this issue. In Windows 11 22H2 and lastest Insider Builds (Dev & Canary) this are worked fine.

Still an ongoing issue. It just broke my fresh install of Win11 build 23466.1001

I created a .reg file after copy and pasting this into a reg file. However after downloading PowerRun v1.6 after adding the .reg file to PowerRun when I run it I get an error...

[ionuttbara]

put
Windows Registry Editor Version 5.00 in first line

[ionuttbara]

this is the listed key

[stimpy81]

OK, many thanks! Adding that line got rid of the error.

I notice that even after a restart that SmartScreen.exe is still running, is this normal, what exactly are those registry keys doing?

[ionuttbara]

re-register smartscreen classes in Windows
