## TL;DR
A hang applying updates on shutdown is usually not the update itself but shutdown ordering: a service or driver refuses to stop while the servicing stack waits to commit. If the percentage has not moved in two hours, a forced power-off is normally safe because Windows rolls back incomplete offline servicing on the next boot; afterwards, read the CBS and event logs, find the service that hung shutdown, and patch interactively next time.

system hang failure applying updates on shutdown
```

## Use this when
- The screen shows Working on updates, do not turn off, unchanged for over two hours.
- Or the machine sits at Shutting down with update activity long past the window.
- The same host hangs on shutdown even without updates, suggesting a service problem.

## Not for this skill when
- The percentage is still changing, even slowly. Let it run.
- The machine is a DC or holds an un-replicated role mid-change. Prefer waiting and vendor guidance over a forced power-off.

## Steps
1. Note the percentage and wait a full additional 30 minutes to confirm it is truly static. Verify: no change in percentage or disk activity
2. Force power off (hold power, or use the hypervisor power action for a VM), then power on. Verify: Windows starts and either finishes or rolls back the update
3. Once logged in, check Update history for the result and read the System event log around the hang for service timeout events (for example 7011) and servicing errors. Verify: the service or component that stalled shutdown is named or ruled out
4. Run DISM restore health and SFC to clear any partial servicing state. Verify: both complete cleanly
5. Install the pending updates interactively from Settings while watching shutdown behavior, after updating or fixing the implicated service or driver. Verify: the machine installs and restarts normally within the window

## Variant phrasings
### working on updates stuck shutdown hours force restart safe
The decision phrasing admins search mid-incident.
### windows shutdown hangs applying updates service timeout
The root-cause phrasing.
### trustedinstaller hang shutdown update commit
The servicing-specific phrasing.

Compatibility: Compatibility: Windows 10, 11, and Server; hypervisor power actions apply to VMs.

## Why it happens
Offline update configuration happens between shutdown and startup, and Windows cannot begin it until every service stops. A service waiting on a dead dependency, a print or backup driver that will not unload, or a servicing worker waiting on a locked file can freeze the whole sequence at a static percentage. The rollback design makes a forced restart recoverable in the overwhelming majority of cases.

## Edge cases / pitfalls
- Hosts that hang on every shutdown, updates or not, have a standing service fault; fix that outside the patch window.
- For VMs, use the hypervisor ACPI shutdown first and hard power-off second; the distinction matters for filesystem state.
- If forced restarts become routine for a model of laptop or server, correlate by driver version; vendors fix these in driver updates, not Windows patches.
