Registry Booster scan will fix any errors reported, after you do a system restart. However, certain programs running in the background might be re-creating some invalid entries. This usually results in Registry Booster fixing a large number of registry errors the first time it is run, but a small number of errors might keep reappearing after each reboot. In order to eliminate these errors once and for all, you will have to find which program is responsible for re-creating these registry entries, although you should not bother too much if the number of errors is minimal.
