using registry cleaner, i can fix all my registry error except those which involve norton - and a few others.\
Examples:
HKEY_LOCAL_MACHINE\software\norton\{0c55c096-0f1d-4f28-aaa2-85ef591126e7}\objid\{e604ee0d-00fd-4531-993e-eecd09d11f63}\
HKEY_LOCAL_MACHINE\software\norton\{0c55c096-0f1d-4f28-aaa2-85ef591126e7}\common client\pathexpansionmap\
HKEY_LOCAL_MACHINE\software\norton\{0c55c096-0f1d-4f28-aaa2-85ef591126e7}\common client\pathexpansionmap\
