This is the only method I'm aware of:

at an admin command prompt enter:

fsutil behavior set memoryusage 2

Oh, already knew this one, and it is only for NTFSMemUsage. I want one for the whole file system.

I did run across this other registry setting. On my XP machine with only 1 GB ram it didn't help but on my Vista machine with 2 GB it seemed to keep the Minimum Benchmark in HDTune from dropping down to single digits as it usually does. So
