bug(windows): unexpected entries in Keyboard layout list after installing/deinstalling keyboard

Following misbehaviour is observed on Win11 arm:

1. Installing keyboard `Khmer Angkor` --> `Keyboard layout` lists `English (United States)` and `Khmer (Khmer Angkor)` which is as expected
2. With additional installation of keyboard `Kreative SuperCyrillic` (select Russian) the `Keyboard layout` is not only enhanced with `Russian Kreative SuperCyrillic` but in addition with a `Khmer Khmer` which is unexpected. (The `Khmer Khmer` will disappear after reboot.)

A similar issue occurs if one of `Khmer Angkor` or `Kreative SuperCyrillic` is uninstalled, and Windows is rebooted: The resulting `Keyboard layout` has the uninstalled keyboard removed but there are two additional entries `Khmer `and `Russian `(screenshot shows `Keyboard layout `after deinstallation of `Khmer Angkor`). The two unexpected keyboards are removed after rebooting.

Issue is not observed with Windows 10.
