No, the 25H2 EP is still RP channel, so not advised to install it atm on retail channel installs. The LCU released today will only show us if it gets offered on retail channel installs who already did the manual install of the 25H2 EP, if that happens on the installs people did to test this, then you could go and try it for yourself but the 25H2 is still RP channel level. And it will only bump the 26100 > 26200 without any new feature added, they even remove some existing stuff like Powershel 2.0.
26100.6584 (24H2) and 26200.6584 (25H2) September 2025 security updates are out The minor build bump is to bring them back in line with a previous, temporary dev channel build number bump Fixes: [App compatibility] Addresses an issue that caused non-admin users to receive unexpected User Account Control (UAC) prompts when MSI installers perform certain custom actions. These actions might include configuration or repair operations in the foreground or background, during the initial installation of an application. [File server] This update enabled auditing SMB client compatibility for SMB Server signing as well as SMB Server EPA. This allows customers to assess their environment and identify any potential device or software incompatibility issues before deploying the hardening measures that are already supported by SMB Server. For detailed guidance, see CVE-2025-55234. [Input] This update addresses an issue that caused certain apps to stop responding input in some input method scenarios. [Input] This update addresses an issue that caused some Internet Information Services (IIS) modules to disappear from IIS Manager, preventing users from configuring IIS using the IIS Manager interface. [Networking] This update addresses an issue that affects audio in apps using the Network Device Interface (NDI). Audio stutters when Display Capture is on in OBS Studio Application. This can occur after installing KB5063878.
@Enthousiast I would like to express publicly my gratitude to the effort of keeping MDL runing alive and wild... You, @abbodi1406 and many other gurus making the difference here. THAK YOU!!! All you guys
The RP 25H2 EP now is Preview, so it is kinda public and still applies to LTSC too, considering this probably is not going to be a "feature adding" but "feature removing" (repair) release it probably will be ok for LTSC too. Iirc brandon leblanc somewhere said that new features were postponed. ADDITION: When you want to know for sure you could wait and see if something official will be announced for 2024 LTSC or what happens on WU!!!
fyi the EKB still mentions Dev Channel Newer one is going to be pushed alongside the next RP flight it seems
fresh installed 25H2 EP and 26100.6548 all is well no file manager lock ups, storage cleanup no delay now or anything weird knock-on wood
@Muggaen Thank you for the clarification. Here is the issue. My friend's laptop, which is on 24h2 26100.4484, pops this message lately (first image). The text in the beige box says "Reinstall the current windows version to repair files and system elements" and the button below says "Reinstall now". When the button is pressed, the blue window (second image) comes up and says "We will repair elements and system files", while the checkbox is for "Automatically reboot my pc 15 minutes after the installation". 5-10 seconds after clicking ok on the blue window above, the installation/repair fails with the message "The repair version of windows was not found. try again later" (third image). And it happens every single time. Any ideas on that? The user does not even know how to get to the windows update menu under settings (unless she asks chatgpt), let alone install a preview update!
No need to install preview updates anyway, they are optional. I had to use the search function to find the post you probably are replying to, may i ask what is the reason for your actions with the build-in repair function? Maybe better to create an uptodate ISO and use it for inplace/repair upgrade.
