Microsoft released Windows 11 build 22635.4445 to the beta channel on November 8, offering Windows Insiders a number of fixes for File Explorer and the taskbar. But the build also contains some undocumented stuff regarding file sharing. As @phantomofearth discovered, Microsoft is testing more areas for file sharing.

In future Windows 11 updates, you’ll be able to share a local file from the Recommended section of the Start menu. Right-click the file and click Share. Jump lists are handled similarly; A Share button appears next to the button responsible for pinning files to jump lists.

If you’re running the latest Windows 11 beta and want to try out the new Share buttons, here’s how to enable them with ViVeTool:

1. Download ViveTool from GitHub and extract the files into a handy, easy-to-find folder.
2. click Win + X and choose “Terminal (administrator)”.
3. Switch Windows terminal to command line profile using keyboard shortcut Ctrl + Shift + 2 or by clicking the down arrow button at the top of the window.
4. Navigate to the folder containing the ViveTool files using the command CD. For example, if you placed ViveTool in C:\Vive, type: CD C:\Vive.
5. To enter vivetool /enable /id:46493758 and press To enter. This allows sharing from the Start menu.
6. To enter vivetool /activate /id:45738940 and press To enter. This allows sharing from jump lists.
7. Restart your computer.

To revert the changes, repeat the steps above and replace /enable with /disable in steps 5 and 6.
