AIP Context Menu broken after Windows 10 Feature Update

After performing a Windows 10 Feature Update, in my case going from 1909 to 20H2, you might notice that the Context Menu of the Azure Information Protection Client is broken, when right-clicking a File.

While previously displaying “Classify and protect”, you’ll end up with Microsoft.Azip.RightClick. The Context Menu still works though.

The reason for that is, that the registry keys below are getting lost during the Feature Update due to a Bug in the Azure Information Protection Client. To workaround this, you can simply re-create the Keys after the Feature Update completes and the Context Menu will be displayed as it was before.

HKEY_CLASSES_ROOT\AllFilesystemObjects\shell\Microsoft.Azip.RightClick\Icon = C:\Program Files (x86)\Microsoft Azure Information Protection\MSIP.NativeRes.dll,-101
HKEY_CLASSES_ROOT\AllFilesystemObjects\shell\Microsoft.Azip.RightClick\MUIVerb = @C:\Program Files (x86)\Microsoft Azure Information Protection\MSIP.NativeRes.dll,-1001
HKEY_CLASSES_ROOT\AllFilesystemObjects\shell\Microsoft.Azip.RightClick\MultiSelectModel = Player

I raised a bug with Microsoft and I hope the behavior gets fixed in the AIP Client so the workaround is no longer needed. I’ll update the blog post when this is the case.
