If your Windows 11 updates are stuck at 0x800f0991, this DISM + SFC combo actually works.

Windows 11 build 22631 has been throwing the 0x800f0991 error for a lot of people lately. Most guides just say restart, but that doesn't work I put together this verified 2026 guide using the specific DISM and SFC commands that actually clear the component store corruption Hope this saves someone a headache!
