CoworkVMService stopped with no in-app recovery (Windows, Claude 1.2581.0.0)

Environment

• OS: Windows 11 Pro 10.0.26200
• Claude app: 1.2581.0.0 (x64, WindowsApps package Claude_1.2581.0.0_x64__pzs8sxrjxfjjc)
• Service binary: cowork-svc.exe

Symptom
Cowork could not start its workspace VM. No actionable error in-app, and
Cowork's own recovery did not resolve it.

Diagnosis

• Windows service CoworkVMService (display name "Claude") was STOPPED.
• Start type AUTO_START, account LocalSystem, dependency staterepository running.
• Exit codes WIN32_EXIT_CODE 0 / SERVICE_EXIT_CODE 0 — clean stop, not a crash.
• Service binary present and intact.
• No SCM failure/recovery actions configured on the service.

Workaround
net start CoworkVMService — started on first try.

Expected

1. Cowork should detect the stopped service and restart it, or surface a

clear actionable error ("Claude background service is not running — restart").

1. Service should have recovery actions configured (e.g. sc failure ... restart/5000/...)

so Windows auto-restarts it.

Repro
Unclear — the clean exit suggests something issued a stop (possibly an
update/uninstall leftover or prior manual stop) rather than a crash.
