What's Wrong?

Subject: Cowork tab not appearing in Claude Desktop — Windows 10 Pro, Pro Annual Plan

Hi Anthropic Support,

I'm on a Pro annual plan and the Cowork tab is not appearing in my Claude Desktop app on Windows. I've done extensive troubleshooting and the issue persists.

My setup:

  • OS: Windows 10 Pro, Version 22H2, Build 19045.6466
  • Claude Desktop: Latest version (confirmed via Help → Check for Updates — no update available)
  • Subscription: Pro, Annual (renews Feb 24, 2027)

What I've already tried:

  1. Downloaded and reinstalled Claude Desktop fresh from claude.com/download
  2. Enabled Hyper-V, Virtual Machine Platform, and Windows Hypervisor Platform in Windows Features — confirmed all three are on
  3. Restarted the PC after enabling virtualization features
  4. Cleared AppData folders related to Claude
  5. Confirmed my Pro plan is active (visible in Settings → Billing)
  6. Confirmed Cowork appears in Settings sidebar — only Dispatch and Global Instructions options are shown, no activation toggle

The result in every case: only the Chat tab appears in Claude Desktop. There is no Cowork tab.

This matches known GitHub issues #25136, #25692, and #48407, where the yukonSilver VM component is marked as unsupported and blocks the Cowork tab from appearing — even on fully capable Windows 10 Pro systems with all virtualization features enabled.

Please advise on next steps or push a fix to my account.

Thank you, Bill Brander

TL;DR

The issue is likely due to the yukonSilver VM component being marked as unsupported, blocking the Cowork tab from appearing, and a fix or workaround from the Anthropic team is needed.

Guidance

  • The user has already tried various troubleshooting steps, including reinstalling the app, enabling virtualization features, and clearing AppData folders, without success.
  • The issue is similar to known GitHub issues #25136, #25692, and #48407, which may indicate a common root cause related to the yukonSilver VM component.
  • The user should wait for a response from the Anthropic Support team, as they may need to push a fix to the user's account or provide additional guidance.
  • In the meantime, the user can try to check for any updates to the Claude Desktop app or operating system that may resolve the issue.

Notes

The issue seems to be related to a specific component (yukonSilver VM) and the user's setup, and the Anthropic team may need to investigate further to provide a solution.

Recommendation

Apply workaround: The user should wait for a response from the Anthropic Support team and follow their guidance, as they may need to push a fix to the user's account or provide additional troubleshooting steps.
