MemMaid is IMHO a must have if you load a lot of test programs MemMaid will clean the bad registry items left when something is removed. It has a cleaning scheduler so you can have it clean your PPC once a day. Has a very powerful REG editor so no need for another program to do this, all around great program. So to answer your question I use a combination of Quick Menu/Hibernate utility, MeMaid and GibbsUSA.net Auto Reset.
1) MemMaid/ Not free has a free trial
