I use a combination of both of these:
Eusing Free Registry Cleaner AND CCleaner. One picks up what the other one misses......

Also like to hand out a big thank you to czevak and marcuswob for all their efforts in producing this excellent Mod. There are a few minor niggles but nothing play breaking at the moment, and I will get round to reporting them if they interfere with play, but in the meantime...
Herzlichen Dank meine Herren! Mach weiter so...
