Thanks for that batch code man, I'm suffering the same problem with this ridiculous svchost.exe taking up over 60,000K, seemingly doing nothing. I tried out this file as you suggested, and believe I've found the renegade service to be 'SysMan' aka 'Superfetch'.IRONICALLY, in Process Explorer, it explains that the service "Maintains and improves system performance over time". Good job there Vista.. there's no point having a 2 Gig RAM laptop if rubbish like this keeps taking it all up! Anyway, what would your advice be now? Just disable that SysMan thing and see if it works? I'm not sure if it would make long-term system performance suffer as a result, though.. guess I could just always shut down instead of putting the comp to sleep. It just seems a pain in the neck for an svchost process to be taking up such an amount of RAM, when it has so little to do..
