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
