Cowork is missing after a reboot.

ClaudeSetup.log

Tried re-install (even "as administrator") on windows 11 pro. I get an error installation error. See log.

Same here, no cowork tab.

If it helps, in the top of the left hand collapsible area to the right of the chat are two tiny icons for cowork and code. I got here because it wasn't working but then pressed a bunch of buttons to see if the UX had changed and it has.

App-Version: 1.2773.0 (884b37)
OS: Windows
Plan: Pro
Problem: Cowork-Tab fehlt in der UI nach Update
Log: cowork_vm_node.log zeigt nur "Loading vmClient (TypeScript) module" —
kein VM-Boot, kein Tab sichtbar
Letzte funktionierende Session: 13. April 2026

Same. No Cowork tab, Code moved to a button next to chat, but Cowork is nowhere.

Same for me, I see a "yukonSilver" marked as unsupported on the logs

My co-work was working on Windows 11 but then disappeared after an April 15 relaunch - entered an issue yesterday.

Tengo el mismo problema. Windows 10. la pestaña de cowork desapareció y claude code se movió a la pestaña izquierda (puedo ver chats y cluade code) pero cowork no esta. Si lo encuentro en configuración con version beta activado (plan pro), pero no esta disponible para acceder desde la pagia principal de claude code

Same. No Cowork tab, Code moved to a button next to chat, but Cowork is nowhere.

Update: After updating to Claude Desktop Version 1.3036.0 (cf521c), the Cowork tab is still missing from the navigation. The issue persists across multiple app versions (v1.2773.0 → v1.3036.0) on Windows 11 Enterprise Build 26200.8037. This confirms it is not being resolved by app updates alone and likely requires a targeted fix on Anthropic's end.

I login my account in another PC, cowork appears.

Took a little time but working with Claude Chat, I was able to get Cowork back on my Windows 11Home version:
Resolution found for Windows 11 Home users:

• Cowork tab reappeared after enabling two disabled Windows features via PowerShell as Administrator:
• dism /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
• dism /online /enable-feature /featurename:HypervisorPlatform /all /norestart
• Followed by a full reboot.
• Both features were Disabled on Windows 11 Home.
• After enabling and rebooting, Cowork tab appeared immediately in the upper left menu area.
• App version 1.3036.0 (cf521c).

I can confirm that these steps worked with the, as of 17th of April 2026, latest version of Claude Desktop (Version 1.3109.0 (35cbf6)) on my Win 11 IoT LTSC system (Exact version: Microsoft Windows 11 IoT Enterprise LTSC - 10.0.26100 Build 26100).

Adding a data point: Cowork tab works on Windows Home after enabling VirtualMachinePlatform + HypervisorPlatform (no full Hyper-V role required)

Hit the same "missing Cowork tab" symptom and wanted to share what I found, since the resolution contradicts the assumption in #26090 (closed as invalid on the basis that Home can't run Hyper-V).

Environment

• Claude Desktop: 1.3109.0.0 (MSIX, Claude_1.3109.0.0_x64__pzs8sxrjxfjjc)
• OS: Windows Home, build 26200, x64
• CPU: Intel i5-12450H (virtualization capable, HyperVisorPresent: True at baseline)

Initial symptom
Cowork tab completely absent from the Claude Desktop navigation. No error surfaced in the UI.

Log signature (matches the yukonSilver cluster in #25136, #25692, #47327, #48995, #49748)

Log location on MSIX installs — worth noting, since it's not %APPDATA%\Claude\logs as some threads suggest:

%LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\logs\cowork_vm_node.log

Contents before the fix:

[info] [cleanupVMBundleIfUnsupported] yukonSilver not supported (status=unsupported), checking for stale bundle...
[info] [VM] Loading vmClient (TypeScript) module...
[info] [VM] Module loaded successfully

Same pattern as #48995: vmClient loads fine, but the upstream yukonSilver pre-check marks the platform unsupported and hides the tab.

What actually fixed it

Enabling the two lightweight virtualization features that are available on Windows Home (unlike the full Microsoft-Hyper-V-All role, which isn't), from an elevated PowerShell:

Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform -NoRestart
Enable-WindowsOptionalFeature -Online -FeatureName HypervisorPlatform -NoRestart

Reboot, relaunch Claude Desktop — Cowork tab appears and is functional.

• #26090 was closed as invalid on the premise that Home lacks the virtualization stack Cowork needs. Based on this repro, that's not quite right — VirtualMachinePlatform + HypervisorPlatform (both available on Home) are sufficient to pass yukonSilver. The full Hyper-V role doesn't appear to be required.
• Regardless of whether Home is officially in-scope, the current UX silently hides the tab instead of surfacing the unmet requirement. A clearer error ("Cowork requires Virtual Machine Platform and Windows Hypervisor Platform — enable them in 'Turn Windows features on or off'") would have saved a couple of hours of log-spelunking and avoided the $99 Pro-upgrade path that several threads currently recommend.

Same issue here, confirming on macOS.

Version: 1.3109.0 (35cbf6)
OS: 26.3.1 (a) (25D771280a)
Plan: Paid subscriber

Repro:

1. Cowork and Code tabs were visible and working in the desktop app earlier today (April 17, 2026).
2. Opened the app later in the day — only the chat interface is visible, no tabs at all.
3. Fully quit and relaunched the app (Cmd+Q / full quit, not just window close). No change.
4. Confirmed signed in to the correct account with paid subscription. No change.
5. No update prompt shown; no error messages displayed.

Expected: Cowork and Code tabs visible in top navigation as they were earlier today.
Actual: Only chat interface, no tabs.

Local Cowork project files in ~/Claude-Workspace/ are intact — this appears to be a UI/app-level issue, not data loss. Happy to provide logs if helpful.

Both Cowork and Code tabs are missing for me. Win 11, latest Claude Desktop version.

I have important work started in Cowork. I can probably figure out how to retrieve it, using Claude Code CLI -- but this is at a minimum inconvenient and costly in terms of my time.

I have the same issue
I can't access cowork on my Win 11 pc.

did this as well

This is annoying as i have a pro subscription and i wanted to see whats the hype about.

Please give a fix.

Same. No Cowork tab

same

Experiencing the same issue. Cowork tab completely absent from Claude Desktop on Windows.

Environment:

• OS: Windows 11 Pro (x64)
• Claude Desktop: v1.2581.0
• Hyper-V: Enabled and confirmed active via Get-WindowsOptionalFeature
• Virtualisation: VT-x enabled in BIOS

Symptoms:

• Cowork tab does not appear in sidebar
• No error messages displayed in the UI
• Paid plan confirmed

Log output (cowork_vm_node.log):
Repeated entries from April 15–17:

[info] [cleanupVMBundleIfUnsupported] yukonSilver not supported (status=unsupported), checking for stale bundle...

On April 17 the VM module loaded successfully but the tab still did not appear:

[info] [VM] Loading vmClient (TypeScript) module...
[info] [VM] Module loaded successfully

Attempted fixes (none resolved):

• Full app restart and machine reboot
• Enabled Hyper-V (was previously disabled, enabled via Enable-WindowsOptionalFeature, confirmed active)
• Cleared VM cache (Remove-Item cowork_vm* from AppData)
• Reinstalled latest version from claude.com/download

This appears to be the same server-side yukonSilver classification issue reported in #25136. The VM config is being marked as unsupported despite a fully capable system.

**UPDATE - this worked

Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform -NoRestart
Enable-WindowsOptionalFeature -Online -FeatureName HypervisorPlatform -NoRestart

I alos have the same issue. Cowrok tab is missing. when will this be fixed?

Same issue. Claude Cowork not showing on my Windows 11 @claude . Only Claude Chat and Claude Code are visible.

<img width="140" height="122" alt="Image" src="https://github.com/user-attachments/assets/77d5f898-ff45-4ce9-874e-7e1d8c280790" />

Not working here either.

Version: 1.3109.0 (35cbf6)
OS: Windows 11
Installed from claude.ai/downloads
CoworkVMService absent from services.msc after clean install
Cowork tab not visible in desktop app

Same. No Cowork tab

Does anyone read the comments? There's been a verified solution.

It's a bit buried in the comments above, so anyone who is looking here this is what worked for me:

1) Go to Windows Features control panel (you can type Windows Features in the Windows search box to get there)
2) Check Virtual Machine Platform and Windows Hypervisor Platform.
3) Let the install happen.
4) Restart your machine when prompted.

Cowork is now visible. Note, the solution in another comment said no restart but it didn't work for me until I did.

Same issue here. Cowork disappeard today on Mac though

My cowork disappeared today

Mine too, with all my projects along with it.
——
Update: Solved. Logged out and logged back in. "Cowork" now appears in the sidebar.

Environment:

OS: Windows 11
App version: Version 1.15962.1 (1e236d)
Date issue appeared: June 27, 2026

Issue:

Cowork tab missing from navigation — only "Home" and "Code" visible instead of "Chat / Cowork / Code"
Steps to reproduce:

Fresh install of Claude desktop app on Windows 11
Launch the app
Cowork tab is absent from navigation

Timeline:

June 26 evening: everything worked fine (Cowork tab visible and functional)
No manual update performed
After shutting down and restarting the PC on June 27, the Cowork tab was gone

What I tried:

Restarting the app — issue persists
Restarting the PC — issue persists
Deleting all local app data (AppData\Roaming\Claude and AppData\Local\Claude) and doing a fresh reinstall — issue persists

Additional notes:

Cowork sessions can still be created by starting a new conversation, so the functionality itself works — only the navigation tab is missing

My cowork also disappeared today. Updating, relogging, restarting nothing helped.

I am experiencing the same issue. I have tried all the methods mentioned above, but it is not being restored.

Has anyone contacted the Anthropic support team officially and received a response or found a solution? I am very frustrated.

Same issue here - Cowork tab missing on Windows 11 Home with all requirements met.

• OS: Windows 11 Home 10.0.26200
• Claude Desktop: v1.18286.0 (MSIX; auto-updated from v1.17377.2 - issue persists on both versions)
• Plan: Pro
• CoworkVMService: installed and Running
• Hypervisor present: True (Win32_ComputerSystem)

Cowork appears to be enabled on the machine:

• Settings > Cowork page renders normally (Cowork files path, trusted folders, global instructions)
• Dispatch (beta) toggle is available and enabled
• Routines and Dispatch appear under "See more" in the sidebar
• "Customize sidebar" only offers Routines / Dispatch / Customize - no Cowork entry

Already tried: full app restart (quit from system tray), sign out and back in, and waiting several days for a possible staged rollout. The Cowork tab still does not appear next to Home / Code.

Also experiencing this on Windows 11.

Environment

• Claude desktop app: v1.18286.0.0 (Microsoft Store / MSIX install)
• OS: Windows 11 Home, build 10.0.26200

Symptoms

• The Cowork tab is completely missing from the sidebar — only Home and Code tabs are shown.
• No error message is displayed; the tab is simply absent.
• Restarting the app does not bring it back.

Happy to provide logs if needed.

Update from my earlier report: Cowork has now appeared on my machine (2026-07-07) - but not as a separate "Cowork" tab. Instead, the Home screen's input box now shows a "Chat / Cowork" toggle, and Cowork works correctly (tested: file inventory and Excel file creation on the Desktop).

Since the official docs still describe a three-tab layout (Chat / Cowork / Code), I'd like to ask: Is this Home-screen toggle the new intended design? If so, other users waiting for the "Cowork tab" may find it there instead.

Environment: Windows 11 Home, Pro plan (same machine as my earlier comment).
