Hi Russell;

  In PB 2017R2 build 1769 - the GetEnvironment ( ) method and its resulting object structure is returning my App's the value 10 for the O/S under W10 Fall Creator Edition for the "OSMajorRevision" property.

HTH

This was listed as one of the bugs fixed in the update posted earlier this week. I'm not sure if it returns a 10 or 7.

This is all due to a change Microsoft made in Windows 8 to the API function to always return 6. They have a new version function that requires a manifest that states the program is compatible with the version. SO if the program is manifested compatible with Windows 8, it will always return 8 even if running on 10.

I have an example that uses a different function to get the version number so doesn't have that limitation.
