Just select them in the Undo section and click on the Ignore button. My guess as to why they are removed is because they do not exist in the location that it says they exist. My guess is also that you are running RegVac in the Expert Zone which suggests that it may not be 100% correct. If you confirm that the above entries are causing that problem, I will enter them permanently into the Ignore list of RegVac.
I typically run in Expert mode. However, even in Novice Mode, it cripples PD 10. The Undo option does not repair the registry because something is blocking it the Undo of the PD 10 registry keys. An error message is issued by RegVac that it cannot undo all the keys. Even in SAFE MODE, it cannot restore.
PerfectDisk 10 has to be uninstalled and re-installed to correct the failures. I haven't been able to figure out what other keys are being improperly removed.
