I would suggest going to Stardock.com
They have this Icon packager (stand-alone) $14.95
I installed the whole suite but used the Icon packager and that resolved my
icons which appeared corrupt during the upgrade. (all the folders, etc)
Anyway, with the above package you can change all your system icons if you
want.
It was worth the money and no hassle.
I have yet to find or locate a fix for the corrupt icons, after upgrading.
