[BUG] Cowork tab missing on Windows 10 Pro 22H2 — CoworkVMService running, logs folder never created, clean reinstall does not fix

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

The Cowork tab is completely absent from Claude Desktop — only Chat and Code
tabs are visible. No error message is shown. Unlike other reported cases, the
Cowork VM service IS installed and running, yet the app still does not show
the tab and never creates a logs folder, suggesting Cowork is blocked before
initialization.

Diagnostics:

• Claude Desktop: 1.20186.1.0 (MSIX package, confirmed via Get-AppxPackage)
• OS: Windows 10 Pro 22H2, x64
• Plan: Pro
• Virtualization: Enabled (confirmed in Task Manager)
• Hyper-V: vmms service Running
• CoworkVMService: installed and Running (confirmed via Get-Service)
• %APPDATA%\Claude\logs: never created (Test-Path returns False)

Troubleshooting already performed:

• Full app quit (system tray) and relaunch
• PC restart
• Enabled Hyper-V and Virtual Machine Platform, restarted
• Clean reinstall: uninstalled via Settings, deleted %APPDATA%\Claude and

%LOCALAPPDATA%\Claude, restarted PC, fresh installer from
claude.com/download run as administrator

• Issue persists after all of the above

What Should Happen?

Cowork tab should appear alongside Chat and Code for a Pro account on a system meeting all published requirements.

Error Messages/Logs

No error messages are displayed anywhere in the app — the Cowork tab is 
simply absent.

No log files exist: %APPDATA%\Claude\logs does not exist 
(Test-Path returns False), indicating Cowork is blocked before it ever 
attempts to initialize and generates no logs.

Checked Windows Event Viewer → Windows Logs → Application: 
[check this and report what you find]

Steps to Reproduce

1. Install Claude Desktop 1.20186.1.0 on Windows 10 Pro 22H2 (x64)
2. Sign in with a Pro plan account
3. Observe only Chat and Code tabs — Cowork tab is absent

Additional Information

• This differs from most existing Windows Cowork-tab issues: in my case

CoworkVMService IS installed and Running, yet the tab still does not appear.

• Get-Service vmms confirms Hyper-V Virtual Machine Management is Running.
• Installed package confirmed as MSIX via Get-AppxPackage (not legacy .exe/Squirrel).
• The same clean-reinstall procedure that resolves this for other users did

not resolve it here.
