Grunt metadata

Software\Grunt
    architecture = <x64 or arm64>
    Version      = <semantic version>
    Revision     = <revision identifier>
    content      = <content directory path>
    variant      = <variant>
    ClientId     = <client identifier>
    updateStrategy = <optional update mode>
For per-user installs, set updateStrategy under HKEY_CURRENT_USER\Software\Grunt to control updates. Use 1 for automatic updates, 2 for manual updates, and 0 to keep update availability silent and prevent automatic installation. See Update management for the recommended per-user command.
On 64-bit systems, the installer also mirrors the registry entries under Software\Wow6432Node\ for compatibility with 32-bit Office.
