Fixes #4447. Fixes #4222. The symptoms for these two issues are related: the language associations change and keyboards stop functioning correctly. The issue is described in detail in #4447. Although this fix should be considered 'experimental', we should probably include it in the release of 14.0, because it fixes a longstanding issue with Keyman and Windows languages.

kmrefresh triggers a synchronisation of Windows language data to
|
|
Microsoft's 'cloud'. This process is required to ensure that Windows
|
|
does not stomp over the current language configuration when it
|
|
attempts to synchronise the data back from the cloud, for instance
|
|
shortly after logging into the system.
|
|
|
|
This cloud functionality was introduced in Windows 10 1809? It is
|
|
not present in Windows 7, 8.1 or Windows 10 RTM. The process should
|
|
run without issues on all platforms, however, and just be a no-op
|
|
where the endpoint is not available.
|
|
|
|
The SyncLanguageDataToCloud API endpoint is currently undocumented,
|
|
so this should be considered experimental. Alternative approaches
|
|
have been considered in corresponding issue #4447, but this is both
|
|
lightweight and respectful of user preferences, so this is the
|
|
approach we've opted to take for now. Plus, it works really well.
|
|
|
|
One trick to be aware of is that the sync function fails if run from
|
|
WoW64. So make sure you run the version with the correct bitness.
|
|
I've put this check into the caller app (kmcomapi) rather than in
|
|
this process. kmcomapi does not currently check exit codes but you
|
|
could track them e.g. with procmon if you wanted to verify behaviour.
|
|
|
|
See #4447 for additional information.
