Claude Cowork tab missing on Windows
A missing Cowork tab on Windows usually means your machine lacks the full Hyper-V stack. Cowork needs the vmms service, which only Windows 11 Pro and Enterprise include, not Home. Run Get-Service vmms in PowerShell: if it's missing, upgrade to Pro or Enterprise. On Pro, enable Hyper-V and Virtual Machine Platform, reboot, and update Claude Desktop.
Likely cause
Cowork needs full Hyper-V (the vmms service), which only Windows 11 Pro / Enterprise has - Windows Home lacks it. The in-app readiness check can falsely report 'ready' on Home because Windows 11 still reports its version as 10.0.
The fix
- 1 Run Get-Service vmms in PowerShell - if the service is missing you are on Windows Home and must upgrade to Pro or Enterprise.
- 2 On Pro, make sure Virtual Machine Platform and Hyper-V are enabled, then reboot.
- 3 Update Claude Desktop to the latest build and reopen it.

Frequently asked questions
The readiness checker says my system is ready, but the tab is still missing. Why?
On Windows 11 Home the checker can falsely report 'ready' because Windows 11 still reports its version internally as 10.0 and the checker misidentifies the OS. Trust Get-Service vmms instead.
Does Cowork work on Windows 11 Home at all?
Officially no. Home lacks the vmms (Virtual Machine Management) service Cowork's VM requires. The official position is that Cowork needs the Pro or Enterprise Hyper-V stack.
I'm on Pro with everything enabled but still don't see the tab. What now?
This may be the 'yukonSilver' platform-detection bug. The workaround is a clean reinstall: stop and delete CoworkVMService, clear the Claude app data folders, then reinstall the latest build from the official download.
