Changelog

v5.3.1 -- Close Mode Fix (2026-03-23)

• Close mode rewrite (Fix) -- stop-then-restart pattern. Stops CoworkVMService (triggers graceful VM shutdown ~31s), cleans HCS orphans, kills Claude UI, restarts service so it is ready for the next launch. Fixes the Windows behaviour where manually-stopped services ignore ETW named pipe triggers
• Stop-ClaudeDesktop.bat -- new launcher for clean shutdown via Close mode. Double-click to stop Claude without running a repair
• Test-RecentHcsErrors Admin log fix (Fix) -- Admin log code path now skips 0xC037010D events with continue instead of returning shutdown_stale, which was bypassing the >15 threshold on any single event
• Version bump -- Fix updated to v5.3.1

v5.0.0 -- HCS Safety & Close Mode (2026-03-23)

• Invoke-HcsDiag helper (Fix + Watch) -- all hcsdiag calls wrapped with Start-Job + 15s timeout to prevent indefinite hangs when HCS is corrupted. 14 call sites in Fix, 3 in Watch
• ServiceTimeout raised (Fix) -- service stop timeout increased from 8s to 30s. Prevents premature force-kills that cause HCS state corruption
• Graceful service polling (Fix) -- WaitForStatus replaced with polling loop, preventing PowerShell timeout exceptions during slow VM shutdowns
• VHDX handle verification (Fix) -- 3 sites now verify VHDX files are not locked before backup/restore operations
• 0xC037010D threshold raised (Fix) -- from 8 to 15 in Test-RecentHcsErrors. This event occurs on every normal VM shutdown (property query bug) and is not a blocker
• vmcompute restart guards (Watch) -- active session detection + Fix mutex check before vmcompute restart. Threshold raised from >5 to >15. Prevents disrupting running Cowork sessions
• Log paths updated (Fix + Watch) -- primary log path changed to C:\ProgramData\Claude\Logs\coworkd.log with fallback to %APPDATA%\Claude\logs\cowork_vm_node.log
• BootPrep delay increased (Prevent) -- boot-fix task delay raised from 30s to 45s with smart pre-check: skips if CoworkVMService or Claude is already running
• Version bump -- Fix 5.0.0, Watch 5.0.0, Prevent 2.0.0

v4.9.0 -- Guest Connection Timeout Detection (2026-03-22)

• New detection source (Fix) -- reads C:\ProgramData\Claude\Logs\cowork-service.log for isGuestConnected RPC state via new Test-CoworkServiceLog helper
• Guest timeout in HCS detection (Fix) -- Test-RecentHcsErrors now returns "guest_connect_failure" when repeated isGuestConnected polls get no guest response
• Targeted Step 9 recovery (Fix) -- when guest-timeout is detected after 90s, performs HCS cleanup + service restart instead of waiting for the full 240s timeout
• Guest connection health monitor (Watch) -- new Check 10 monitors cowork-service.log for sustained isGuestConnected polling with zero guest responses (3 consecutive checks required before trigger)
• Error patterns expanded (Watch) -- added isGuestConnected timeout patterns to log-scan error list
• README updated with isGuestConnected error documentation, new tracked issues (#31848, #31314), troubleshooting entry, and updated step descriptions
• Version bump -- Fix and Watch updated to v4.9.0
