Is validation really necessary? Obviously activation is, but validation...? If you hide the OGA update it stays hidden forever and "Microsoft Update" functionality is totally unaffected. AFAICT, OGA is ONLY needed for downloading a few extras/addons and the user is never reminded of not having validated as long as they don't require one of these downloads. In fact, although classified as an "important" download on "Microsft Update", the default setting for the OGA update is unchecked - i.e. it will not be downloaded and will not be installed unless the user specifically "ticks the box" and deliberately requests this,... so a user would not even be notified that they were missing it unless they attempt to download an extra/addon. Am I missing something here???? Does not validating have any further consequences other than this?
