bug(windows): 'startup apps' Windows settings do not sync up with 'start with Windows' keyman configuration

### Describe the bug

From community site: https://community.software.sil.org/t/keyman-doesnt-open-at-startup/11280
> I have used keyman for some time, but since a recent update it will no longer open when i restart (the box in configurations is checked).

I am able to reproduce the issue where in Keyman settings "Start when Windows starts" stay checked while Windows startup apps for Keyman Configuration is disabled.

### Reproduce the bug

1. Go to Keyman Configuration -> Options -> Check "Start when Windows starts"
2. Go to Windows Startup apps > Disable "Keyman Configuration"
3. Restart the machine
4. After a reboot, Keyman do not startup but the Options stay checked

### Expected behavior

Could the two settings sync up when one startup is triggered?
