Latest Edge update somehow enabled password Auto-Clear upon closing by itself. Lost every single saved password...
description has changed, now it has proper name "Feature Update for Windows 11 25H2 via Enablement Package (KB5054156)" previous name was "Feature Enablement for Dev Channel Preview Update (KB5054156)"
No you would need to do a full build upgrade to 25H2 using a MS created Win11 v25H2 iso, or create a iso using uupdump.
I've gone from 24H2 to 25H2 on a few systems by letting 24H2 lag behind until the .XXXX of 24H2 is behind the .XXXX of 25H2 on UUPDump.
25H2 is not offered on Windows 10 WU, only in the Release Preview channel. KMS(38), Tsforge or HWID, yes.
