Steps to reproduce the problem:
0. Download the ZIP file with ADMX templates from https://enterprise.google.com/chrome/chrome-browser/
1. Add the ADMX/ADML files in the ZIP file to the PolicyDefinitions location in your domain
2. Open GPMC.MSC, try to edit expand the "Administrative Templates" section 
3. Watch the error message "ADMX errors: Resource '$(string.SUPPORTED_WIN7)' referenced in attribute displayName could not be found" pop up, and the "Google" subfolder in the GPO disappeared.

What is the expected behavior?
The ADMX templates load without comment, problems or error messages and (Google) policies can be edited

What went wrong?
You have changed "SUPPORTED_WINXPSP2" in the ADMX file to "SUPPORTED_WIN7" but neglected to include this ID into the various ADML files.

Did this work before? Yes

I fixed this for my own templates as I need to get stuff done, but please fix this and test better in the future.
