Claude Cowork on Windows: what it can do, what changed and its limits

Guide · updated November 2026 · Protime

In short: Claude Cowork works on Windows through the Claude desktop app, with a paid plan. In 2026 it changed twice in ways many guides have not caught up with: since September 16 Cowork and chat are being merged into a single Claude, so the “Cowork” tab is disappearing; and since October 6 new tasks on Pro and Max run in Anthropic's cloud, not on your PC. Claude can still work with your files, but only in the folders you connect and only while the desktop app is open; the file it needs is copied to the cloud session. With computer use it can also operate Windows programs. What it no longer does is run a task entirely on your computer: for that, Anthropic points to Claude Code.

What changed in 2026

When	What changed	What it means on Windows
February 2026	Cowork arrives on Windows	Same features as on Mac, inside the Claude desktop app
Spring 2026	Computer use on Windows (research preview, Pro and Max)	Claude can open programs, click and type on screen
September 16, 2026	Cowork and chat start merging into one Claude	Rolling out gradually: when your account moves over, there is no separate Cowork option any more
October 6, 2026	New Cowork tasks on Pro and Max run in the cloud; the “only on your computer” option is removed	Tasks keep going with the laptop closed; local files are reachable only through the open desktop app
By October 2026	Dispatch is no longer offered to new users	No new pairing between the phone and the desktop app for assigning tasks; if an existing one stops connecting, see Dispatch not working

Requirements on Windows

Requirement	Detail
Plan	Paid Claude plan (Pro, Max, Team, Enterprise); computer use is a research preview for Pro and Max
App	The latest Claude desktop app for Windows, from claude.com/download; installing it with full Cowork support needs administrator rights
Windows	Windows 10 or 11 on an x64 processor; Anthropic offers a readiness check tool on its Cowork help page
Virtualization	Tasks that ran locally used a Hyper-V virtual machine: many Windows Home users met “Hyper-V not available” errors, because Home lacks the full Hyper-V stack
Local files	Folders connected in the app, and the desktop app open and online while the task needs them
Internet	Always: the session runs in the cloud

What Cowork can do on Windows

Work on your files in the folders you connect: read, create, reorganize, turn a pile of documents into a report.
Use connectors to email, calendar, cloud storage and other services, and produce documents, slides and spreadsheets.
Use the browser and, with computer use, the programs installed on the PC, asking permission for each app.
Keep going after you close the laptop, as long as the task does not need local files at that moment.
Run scheduled tasks, which now also run in the cloud; the ones that read local files need the desktop app open at that time.

What it cannot do (or only with conditions)

You want to	With Cowork today	Alternative
Run a task only on your PC, nothing in the cloud	No longer possible for new tasks on Pro and Max	Claude Code in the desktop app, which Anthropic recommends for strictly local work
Reach local files with the app closed or the PC asleep	No	Keep the PC on and the app open
Assign a task to your PC from the phone	Dispatch is closed to new users; a cloud task reaches local files only if the desktop app is open on that PC	A remote MCP server connected to Claude, or Codex remote with ChatGPT
Work on the whole disk	Only connected folders	Connect the folders you need
Use another AI	Claude only	ChatGPT computer use, or a server that works with several assistants

A note on privacy: with cloud tasks, a local file Claude opens is copied to the session and processed on Anthropic's servers. That is true of every cloud AI that reads your files, but if a folder must never leave the PC, do not connect it.

Common problems on Windows

The Cowork tab is missing

The most common reason today is the merge: if your account already has the new single experience, there is no “Cowork” option any more, and you simply give Claude the task in a normal conversation. Otherwise check that you have a paid plan and the latest desktop app.

“Hyper-V not available” or “virtualization is not enabled”

These came from the local virtual machine. On Windows Pro, Enterprise and Education, turn on virtualization in the BIOS and enable Hyper-V in Windows features, then restart. Windows Home does not include the full Hyper-V stack. With new tasks running in the cloud, run Anthropic's readiness tool again after updating the app before spending time on it.

Claude cannot see a file

The file must be in a connected folder, and the desktop app must be open and online on that PC when the task needs it.

When Cowork is not the right tool

You want everything to stay local → Claude Code in the desktop app runs on your computer. You want your PC from the phone or from claude.ai without keeping the desktop app in the foreground → a remote MCP server added to Claude as a connector, such as MCP DeskManager (Windows, works from any Claude or ChatGPT chat, the phone apps included; it acts only when you ask). You use ChatGPT → computer use in the ChatGPT desktop app. All the Claude routes side by side are in control your PC with Claude, and every option, other assistants included, in computer use agents: the complete guide.

Frequently asked questions

Is Claude Cowork available on Windows?

Yes, through the Claude desktop app for Windows with a paid plan. As the merge rolls out, it becomes part of the normal Claude conversation instead of a separate tab.

Does Claude Cowork run on my computer or in the cloud?

Since October 6, 2026, new tasks on Pro and Max run in the cloud. Claude reaches your local files through the desktop app, only in connected folders and only while the app is open.

Does Cowork work on Windows Home?

Many Home users hit Hyper-V errors with the local virtual machine, because Home lacks the full Hyper-V stack. Check with Anthropic's readiness tool after updating the app.

Can I use Cowork from my phone?

You can use Claude on the phone, and cloud tasks continue there. Dispatch, for assigning tasks to your PC from the phone, is no longer offered to new users, and local files need the desktop app open on the PC.

Can Cowork control Windows programs?

Yes, with computer use, a research preview for Pro and Max: Claude asks permission for each app, then clicks and types on screen.
