Every time I change the value of the following registry key to "0" and then reboot, the key gets deleted and then a few reboots later reappears with the default value of 3.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\EnableSuperfetch

I've also tried running the following in the Windows PowerShell:

Disable-MMAgent -ApplicationPreLaunch

I've read many guides online suggesting to disable the SysMain service. However SysMain is required for things like memory compression and such that I find beneficial. But I'd much rather not have the SuperFetch enabled; I don't need Windows ravaging my hard drive for 2 to 3 minutes straight after boot and when I close memory hog programs, just so that commonly used applications like a web browser load 3 to 5 seconds faster.

So is there any way to get Windows to stop resetting the registry key? Am I modifying the wrong key for the latest feature update?
