This is really a message to the HDS staff. I think it would be useful to create a mailing list to inform your users of important technical information relating to Rollback RX (not to be used for marketing purposes though).
This should include,

1. News of how major Windows updates are likely to affect Rollback RX users and what they should do to mitigate any risks.
2. News when new incremental versions of Rollback have been released so that users can upgrade.

This would be certainly be halpful and could avoid some problems users have faced in the past.
