This powershell script modifies the Base Image, or the Virtual Hard Disk, which the Windows Sandbox launches upon startup. It will copy the required files to the sandbox and add a registry key which will install them upon startup. By default the script will install the latest stable release of Winget. You can specify to use the latest pre-release with the -PreRelease switch.

When a new version of Winget is released, run this script again to update the installation in the sandbox to the latest version
