Same deadlock as #51132. New data point: I successfully deleted CoworkVMService, and the MSIX package remains wedged in Status: Servicing. CoworkVMService is a contributing factor but not the root cause. The deployment engine reports finished successfully on every Remove-AppxPackage call while the state repository is not actually being updated. SYSTEM-context removal via PsExec produces the same silent-success failure as admin-context removal.

Error Message

3. Attempt removal — returns without error, no output

Root Cause

Same deadlock as #51132. New data point: I successfully deleted CoworkVMService, and the MSIX package remains wedged in Status: Servicing. CoworkVMService is a contributing factor but not the root cause. The deployment engine reports finished successfully on every Remove-AppxPackage call while the state repository is not actually being updated. SYSTEM-context removal via PsExec produces the same silent-success failure as admin-context removal.

Code Example

## AppX deployment log shows engine-level success on every retry

---

Three identical `Remove-AppxPackage` invocations produced three success traces and three resiliency files (`_1.rslc`, `_2.rslc`, `_3.rslc`) without clearing the registration. The deployment engine reports success, but the state repository is not actually being updated. This is a silent state-repository inconsistency, not a permission or service-blocker issue.

## Package state

---

Two notable fields:

- `PackageUserInformation: {S-1-5-18 [NT AUTHORITY\SYSTEM]: Staged}` — registered to SYSTEM, not to the interactive user. Explains why user-context `Remove-AppxPackage` is rejected, but does not explain why SYSTEM-context removal also silently fails.
- `SignatureKind: Developer` on a production-signed Anthropic package. Unusual. Developer-signed packages have different removal-flag semantics than Store-signed packages and may interact unexpectedly with `RemoveForAllUsers` deployment options.

## Steps that did NOT clear the wedge

| Step | Result |
|---|---|
| `sc.exe delete CoworkVMService` | Succeeded — confirmed removed via `sc.exe query` returning 1060 |
| `Remove-AppxPackage -Package <FullName> -AllUsers` (admin context) | Silent success, package still registered |
| `Remove-AppxPackage -Package <FullName> -AllUsers` (SYSTEM context via `PsExec -s -i`) | Silent success, package still registered |
| `Get-AppxPackage -AllUsers Claude \| Remove-AppxPackage -AllUsers` (SYSTEM context) | Silent success, package still registered |
| `Stop-Service AppXSvc -Force; Start-Service AppXSvc` followed by retry | No change |
| Full system reboot followed by retry | `Status: Servicing` persists |
| Bootstrapper `Claude Setup.exe` reinstall | Fails with `0x80073CFA` on Remove, then `0x80073D28` on Add |

## What this rules out

- CoworkVMService is not the root cause. Service successfully removed, wedge persists.
- Insufficient privilege is not the cause. SYSTEM context produces identical silent-success behavior.
- Stuck deployment service is not the cause. AppXSvc restart and full reboot do not clear `Status: Servicing`.
- Active operation is not the cause. No background activity; `Status: Servicing` is a stale flag in `StateRepository-Machine.srd`.

## What this points to

The bug is in the deployment-to-state-repository write path. `Remove-AppxPackage` succeeds at the `PackageManager` API surface and writes resiliency files, but the corresponding state-repository transaction either never commits or silently rolls back. Once the registration enters this state, no documented user-space tool can clear it.

## Reproducibility across the user base

- #25162 (Feb 2026)`0x80073CFA`, ghost MSIX package
- #47877 (Apr 14, 2026)`Status: Staged`, `0x80073CFA` / `0x80073D28`
- #49917 (Apr 17, 2026)`0x80073CF6` / `0x80073D28`, wedged state after AddPackage on non-removed package
- #51132 (Apr 20, 2026) — full deadlock, all standard recovery steps fail
- This issue (May 09, 2026) — same deadlock, novel evidence that CoworkVMService removal does not resolve it

This is a multi-month, multi-user, unresolved bug.

## Request

1. **Recovery utility** that directly cleans the AppX state repository entry (`StateRepository-Machine.srd` row + `HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore` keys) when `Remove-AppxPackage` returns silent success without effect. The community has no supported path forward at this point.
2. **EXE-based installer alternative** (originally requested in #51132). The MSIX deployment model is producing unrecoverable wedges in the field at a non-trivial rate.
3. **Investigation into the package signature and ownership pattern.** `SignatureKind: Developer` and `PackageUserInformation: {S-1-5-18: Staged}` on a production install is unusual. If the production MSIX is being registered as a Developer-signed, SYSTEM-staged package rather than a per-user Store registration, that may be why `Remove-AppxPackage` does not honor `-AllUsers` correctly for it.
4. **Acknowledgement and tracking.** #51132 was closed without a fix, comment, or assignee. If the team is tracking this internally, please reopen or link to the tracking issue so affected users have visibility.

### What Should Happen?

Claude desktop should install and load, this is what I pay $100 per month for.

[BUG] Vibe Coded Windows Desktop App: MSIX wedged in Status: ServicingRemove-AppxPackage returns silent success without clearing registration (HRESULT 0x80073CFA / 0x80073D28)

Preflight Checklist

Summary

Same deadlock as #51132. New data point: I successfully deleted CoworkVMService, and the MSIX package remains wedged in Status: Servicing. CoworkVMService is a contributing factor but not the root cause. The deployment engine reports finished successfully on every Remove-AppxPackage call while the state repository is not actually being updated. SYSTEM-context removal via PsExec produces the same silent-success failure as admin-context removal.

Environment

  • OS: Windows 11 Professional, build 10.0.26200, x64
  • Claude package version: 1.6608.2.0 (Claude_1.6608.2.0_x64__pzs8sxrjxfjjc)
  • Sideloading enabled: yes
  • Developer Mode enabled: yes (AllowDevelopmentWithoutDevLicense=1)
  • Date issue started: 2026-05-09, immediately after a Claude Desktop auto-update

Reproduction


# 1. Confirm CoworkVMService is gone
sc.exe query CoworkVMService
# [SC] EnumQueryServicesStatus:OpenService FAILED 1060:
# The specified service does not exist as an installed service.

# 2. Elevate to SYSTEM via PsExec
PsExec64.exe -s -i powershell.exe
whoami
# nt authority\system

# 3. Attempt removal — returns without error, no output
Remove-AppxPackage -Package 'Claude_1.6608.2.0_x64__pzs8sxrjxfjjc' -AllUsers

# 4. Package still registered
Get-AppxPackage -AllUsers Claude | Select-Object PackageFullName, Status
# PackageFullName                       Status
# Claude_1.6608.2.0_x64__pzs8sxrjxfjjc  Servicing
