Intermittent 1-Second Windows Command Prompt Popups While Using Cursor

Support Bug Reports
1

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

While using Cursor on Windows, brief Windows Command Prompt windows intermittently appear and disappear (lasting approximately one second). This occurs repeatedly during normal usage of the IDE and did not occur prior to a recent update

Steps to Reproduce

Launch Cursor on a Windows machine.

Open any project or file.

Use Cursor normally (typing, navigating files, invoking commands, or interacting with the UI).

Observe that Windows Command Prompt windows intermittently appear for ~1 second and then close automatically.

Expected Behavior

Cursor should operate without spawning or displaying any Windows Command Prompt or terminal windows during normal usage. All background processes, scripts, or update-related tasks should run silently without disrupting the user experience or stealing focus.

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

Version: 2.2.20 (system setup)
VSCode Version: 1.105.1

Chromium: 138.0.7204.251
Node.js: 22.20.0
V8: 13.8.258.32-electron.0
OS: Windows_NT x64 10.0.26200

Additional Information

Issue began yesterday and was not present prior to a recent Cursor update.

The behavior is disruptive and suggests a background process spawning a visible terminal window.

Seeking confirmation on whether other Windows users are experiencing the same issue.

Does this stop you from using Cursor

Hey, thanks for the report. Looks like a known issue on Windows, the team is already working on a fix. Need details to speed this up.

Please check:

  • Update Cursor to the latest version and restart
  • Run from command line: cursor --disable-extensions and check if the window appears
  • Enable Settings > Application > Experimental > Extension Monitor Enabled, then Ctrl+Shift+P > Developer: Open Extension Monitor and Developer: Open Process Explorer. At the moment of popup, take a screenshot of which process is launching
  • Open Help > Toggle Developer Tools > Console and attach errors/logs from the moment of popup

And share:

  • Short video or screenshot of the popup window with title
  • List of installed extensions
  • Are you using WSL or non-standard terminal by default

Report back with results, I’ll continue investigation with engineers.
