Re: Windows Defender Firewall not starting if changing Systemlanguage
Malex17 I found a workaround in the topic at Reddit and confirmed it fixes the issue. I downloaded Windows 10 22H2 from October, created an Operating System Upgrade Package in SCCM and used this image for the upgrade. I then applied all my language packs in the TS (EN, NL, FR), rebooted the machine and then applied the LCU (Latest Cumulative Update) which in this case was KB5021233. After applying the patch and rebooting the pc, the Windows Defender Firewall is working fine again when the pc boots with NL set as system language. I have now started a new test with the 22H2 from December and the LCU from Januari (KB5022282).6.4KViews1like3CommentsRe: Windows Defender Firewall not starting if changing Systemlanguage
Malex17 I have the same issue and discovered this yesterday when upgrading machines from Win10 20H2 and 21H2 to 22H2. Tried everything to get Windows Defender Firewall running again but nothing worked. This morning I upgraded two test machines from 21H2 to 22H2 while closely monitoring the SMSTS.LOG and running a ping. After the OS upgrade everything was still fine, but after the language packs installed (nl-NL, fr-FR, en-US) and the machines rebooted with nl-NL as default system language, they could no longer be reached over the network. After the TS completed I checked the machines and they both failed to start the Windows Defender Firewall. If I change the default system language to en-GB, set it as default language for new user accounts and the welcome screen and reboot, ONLY THEN does the Windows Defender Firewall start. This is a big issue and we need a solution ASAP. We have over 2500 machines that need to be upgraded to 22H2 by the beginning of May and this is a blocking issue! From what I read in the other threads, people are able to solve it by using an older build of 22H2 and patching it in the TS prior to installing the language packs, but that is quite the hassle and not a good solution imo.6.4KViews0likes0Comments
