Hi Dagmara,
What Insider build are you on?
Use WIN+R, type winver for the build #.
What is the Update fail error showing
in Windows Update History?
Unable to update Windows

2026-09-13T02:37:28.5866667+00:00 Hey! I have a Microsoft Surface with Snapdragon X, ARM64. I’m running Windows 11 Home Insider Preview 26H2 build 26300.8697. SFC found corruption it could not repair. DISM /RestoreHealth failed, Windows Update feature updates fail, Reset this PC fails because required files are not trusted, and DISM now reports Error 14098: “The component store has been corrupted.” I need the official ARM64 Windows 11 26H2 build 26300.9278 ISO or VHDX to use as a DISM repair source or for an in-place repair that keeps my files and installed apps.
