## TL;DR
DISM 0x800f0954 during RestoreHealth usually means policy is steering repair content to a WSUS server or source that does not carry it. Point DISM at matching local installation media with an explicit source and limit access to Windows Update for that run, or fix the group policy repair source setting. The component store is not necessarily more damaged - DISM simply has nowhere valid to fetch clean files from.

## Use this when
- DISM RestoreHealth fails quickly with 0x800f0954 on a domain joined or WSUS-managed machine.
- The same machine updates normally through WSUS, but repair content downloads fail.
- Group policy configures an alternate source path or specifies contact Windows Update settings for repair.

## Not for this skill when
- RestoreHealth runs for a long time and fails with a source files not found code on an unmanaged machine. Use local media per the source files skill.
- DISM fails before any source lookup with an invalid image or architecture error. Fix the command and image first.

## Steps
1. Confirm the installed edition, version, and architecture with winver and DISM Get-CurrentEdition, and obtain installation media for the same release. A mismatched source is rejected silently or produces a second failure that hides the first. Verify: the media edition and build match the installed system and the image index for that edition is noted
2. Check the policy steering repair: review the group policy setting for specifying settings for optional component installation and component repair, and note whether it names an alternate source path or blocks Windows Update contact. Record the current values before changing anything. Verify: you can state exactly which source DISM is being sent to by policy, with the setting values recorded
3. Run RestoreHealth with an explicit local source from the mounted media and the LimitAccess switch, so the run ignores the broken policy source entirely. Allow it to complete and read the final DISM log lines rather than the progress percentage. Verify: RestoreHealth completes successfully using the local source, or the log shows a specific missing payload instead of 0x800f0954
4. Run DISM ScanHealth again without LimitAccess and then sfc /scannow to prove the store is now healthy through the normal path. If ScanHealth passes, the original fault was the repair source, not ongoing corruption. Verify: ScanHealth reports no corruption and SFC completes, ideally reporting no violations after repairs
5. Fix the durable setting: either correct the group policy alternate source to a share that actually carries repair content for your builds, or set policy so repair can contact Windows Update directly while normal updates still use WSUS. Test one machine before wider rollout. Verify: a second managed machine completes RestoreHealth without a local media workaround

## Why it happens
RestoreHealth needs clean replacement payloads. On managed networks, policy often directs that traffic to WSUS or to a file share configured years earlier for a different Windows release. WSUS does not serve all repair content, and a stale share lacks current payloads, so DISM fails the lookup with 0x800f0954 even though the machine updates fine day to day. The store damage that triggered the repair may be minor. Supplying a known matching source for the immediate repair, then correcting the policy source for the fleet, separates the one-off fix from the systemic cause.

## Variants and edge cases
### 0x800f0954 on Windows Server features install
Adding roles or features uses the same repair source path. Mount matching server media or fix the alternate source policy before retrying the role install.

### 0x800f0954 after a feature update changed the build
Old repair shares and media no longer match after an upgrade. Refresh the source media to the new build and update the policy path in the same change.

### Specify settings policy set but source share empty
An empty or permissions-blocked share produces the same code. Verify a test account used by the system can read the payload folders on the share.

Compatibility: Applies to Windows 10, Windows 11, and Windows Server 2016 and later managed by WSUS or group policy.
