Windows Defender Firewall not starting if changing Systemlanguage

Occasional Contributor

Initial situation: We're using the Windows 21 and 22H2 (englisch, international = en-GB) as Baseimage and are integrating a couple of Languagepacks via offline imaging (cab, lip and lxps)

During the inital installation phase, depending on the operational site, the Systemlanguage is changed to another language (for e.g. de-DE).

This worked for YEARS without any problems.

Since August / September 2022 this constellation is not working anymore. If the Language is set to another than en-GB some services are just not starting anymore. (e.g. Windows Defender Firewall)

 

Currently our workaround is to change the systemlanguage back to en-GB.

Reinstalling the LanguagePacks offline or online does NOT solve this problem.

We have exactly the same problem, the installation of the language packs is not a problem, but as soon as the language is changed, the firewall no longer works. (And a Firewall reset is also not possible)

 

We install the CAB files during the task sequence and then apply the language with the Language Settings xml.ApplyLanguage.png

 

 

I have also found other people who encounter this problem but no solution so far:
