system mechanic should have cleaned up the orphans in the registry. maybe
the trial ware is limited or you didn't make to correct selections.
but in any case you this registry program from
http://www.worldstart.com/weekly-download/archives/reg-cleaner4.3.htm
it is super powerful and has the ability to destroy your system. But if you
use it the right way and don't use all of the extra features, it will be
your best computer friend, kindalikeme....
You can sort by colume one, make your selections and delete.
Then sort again by colume 2 and make your selections and delete.
You can right click on any entry that seems ambigious and all the files will
be listed and provide additional information about the software.
Basically all the tabs are helpful, but a couple may be a waste of time to
use. Incidently do not delete your unistall line items unless you know the
programs are no longer on your system. Otherwise, if you do delete any of
them, you will have difficult time in add/remove programs if you want to
uninstall anything in the future.
And only one menu item under tools>registrycleaner>orphans... is ok to use.
All the other ones can crash your system, not becuase they are defective,
but becuase they are powerful....
Afterwards, reboot for the registry to take affect. Before you do anything
above, create a restore point-for just in case.
