With the latest Windows 11 insider preview build (22635.4225 for beta testers), Microsoft has added the ability to reprogram what the Copilot button launches. The new option can be found buried in the Settings app under Personalization > Text Input. From there, you can pick an "MSIX packaged and signed" app.

Microsoft is planning to allow Windows 11 users to customize the Copilot key that has started shipping on new laptops and keyboards. The Copilot key is configured as default to launch Microsoft’s Copilot app on Windows 11, but the company is now testing the ability to use it to launch other apps instead.

To change the Copilot key behavior, just head to Windows Settings > Personalization > Text input and select the "customize Copilot key on keyboard" option. If you have a PC without a dedicated Copilot key, changing this setting won't do anything, Microsoft says.

Microsoft is testing a new feature in Windows 11 that lets users remap the Copilot key on their laptops. This feature is currently being rolled out to Insiders in the Beta Channel.

Microsoft has officially launched a new Windows app designed for a variety of platforms, including macOS, iOS, iPadOS, Android, and Windows PCs.
