I have been using regseeker for quite a long time. I delete all the items it finds and have never had a problem. I have noticed that alot of the red items seem to come back, like windows is recreating them so I quite doing those lately. As for the green ones delete them all. If you have the option checked to save the deleted entries you can add them back in if something doesnt work.

in the regseeker directory there is folder called backup. In there are all the registry entries that were deleted. To add them back in if you need to just double click on it and select yes. This will put those entries back in the registry.
