Heather,

Does the Windows team know the "Repair My PC" feature from the Windows ISO has been broken since May?  MS replaced the WinPE version of RecEnv.exe with the Cloud rebuild version from WinRE.  Except they forgot to include two required DLL's, wlanapi.dll & mobilenetworking.dll

When you boot the ISO and select Repair My PC, it currently fails.  Copying the missing DLL's into boot.wim fixes the problem.  This condition impacts all current Windows ISO's from May 2026 and onward, including MCT and all of the Insider ISO's.
