Thanks for replying. I guess I am used to a program that if it asks to reboot to make changes, it usually commences upon start-up and reports actions taken and the reasons.
I did look at the logs (for some reason nothing showed up in the logs window in the program but I found them with explorer) and it was was not clear whether all the entries were for problems found and repaired on the system or just entries that had been written to the "correct" values or files replaced regardless of the current state.
There were no problems with the system, I was trying to fix specifically, just trying to bring it to the best possible health.
thanks again, Alex
