Hi Mike, slightly off topic, but in regard to your wise suggestion about doing a *_Restore Point_*. Have you personally had success with “Restore Point Recovery” under e.g. Win-10 (PRO) ?
No Win10 here. I run Win7 Pro on the observatory PC and Win 8.1 Pro on my office PC. I have successfully applied a Restore Point on on both platforms to recover previous files and programs.
