I appreciate @garlin's scripts to fix this issue and other secure boot issues. These are temporary work-arounds., as using uup dump to get the latest isos that actually work. MS has many issues to fix before releasing 26H2 as a public release.
Well ISO Repair install from the UUP Dump didn't fix the DISM Restorehealth error 0x800f0915

On one of my machines, a Dell desktop, I wasn't able to repair the DISM issue with a uup dump iso either, My other machines have no issues with DISM, except it is sometimes slow.

Another issue is with the mct download of their installation usb is where the "Repair my PC" doesn't work. It does work on one downloaded through uup dump.

Known issue because UUP dump prepares the boot.wim in a slightly different manner. MCT gives you the untouched boot.wim.

All these new ISO files still have the bug in boot.wim.
"Repair my PC" just causes a reboot of the main OS.
Really? It's been working fine for me last couple of preview builds, so I consider it fixed.

For those that tried a repair install for the DISM issue, was that mounting an ISO and running setup.exe, or through System > Recovery > Fix problems using Windows Update?

LOL, I tired both, but the System/Recovery Reinstall Now started downloading build 26340.XXXX, the Dev experimental build so I canceled it. That method hasn't worked on the DISM bug yet as far as I know though. I then had to do a UUP Dump download (which takes forever to extract) since the Microsoft ISO wasn't compatible with ARM machines and mine is ARM. All to no avail though I'm afraid as the UUP Dump ISO also failed at repairing DISM.

Crazy.

I haven't been able to re-create the DISM issue on a Windows 11 25H2 system (AMD x64) with the August 2026 updates installed.

It's slow, but it works.

With many different builds, if you run /SCANHEALTH after a successful /RESTOREHEALTH it still finds repairable.
This is a mess created by Microsoft and they still did not fix their bugs. 🤬🤷‍♂️
