How to watch an agent's desktop run and stop it with Esc with DSH Computer Use Win

Keep an on-screen view of what an agent is doing, and halt the run at once with Esc or your own shortcut.

Short answer: Install with dsh plugin --profile desktop add dsh-computer-use-win from the DSH terminal, then quit and reopen DSH Desktop; then open Settings → Computer Use and check the screen indicator and mouse indicator options; use the preview option in settings to see how the indicators look on your screen. All steps.

Who it is forA user who is new to letting an agent control their PC and wants clear visual signals plus a reliable way to stop it.

The problemLetting an agent move the mouse and type on your real desktop feels risky without a visible signal and a dependable stop.

The outcomeYou see the agent's activity through screen indicators, step records, and the final summary, and can stop a run at any moment.

What you need first

  • A Windows computer with DSH Desktop installed
  • Windows PowerShell 5.1 (included with Windows)
  • For DSH Web or a standalone MCP client: Node.js 22 or later
  • A logged-in desktop session that the plugin can use

Steps

  1. Install with dsh plugin --profile desktop add dsh-computer-use-win from the DSH terminal, then quit and reopen DSH Desktop.
  2. Open Settings → Computer Use and check the screen indicator and mouse indicator options.
  3. Use the preview option in settings to see how the indicators look on your screen.
  4. Start a small, low-risk task and watch the blue edge glow, the notice bar, and the step records.
  5. Press Esc to test the stop, then send a new task or say continue when you want the agent to resume.

Prompt for your agent

Using the dsh-computer-use-win tools, perform <low-risk desktop task> in <app name> and describe each step as you take it. Stop immediately if the user presses Esc, and report the final state as completed, sent but not confirmed, not completed, or stopped.

Caveat. Esc stops queued and in-progress actions, but input already sent to a program cannot be taken back, and a frozen program must respond before it can stop.

Use this in your AI agent

Ask your agent
