Once you complete the scan you should proceed to the next step where Premium Booster will repair all invalid and orphaned entries, which have been detected during the scan process. At this point you can select which problems you want to be repaired and which ones should be left untouched. All problems are grouped into categories and have different danger level. Press Repair All Categories button to fix all problems. Pressing Repair All Problems button will fix all problems from the selected categories. In case you want to manually select problems to be repaired then you'd have to select those problems in the problems list and press the Repair Selected Items button.

Any repair operation can be undone. To do so simply navigate to the left panel and press the Undo button. Use this option if you need to restore the original content of the some registry keys. In case you'd like to roll back your system to the previous state it may be more appropriate to use System Backup/Restore.
