How do i start superfetch in win 7

The insructions are in that link.

enable or disable Superfetch:

WINDOWS START-> type "services.msc" -> find "Superfetch" and double-click -> click START or STOP then OK

FYI, mine was OFF and I had difficulty finding information as to when it should be on or off. Does it depend on how much RAM and how fast your drives are?

I just don't know. I turned it ON out of curiosity and will see what happens.

Note that it says "startup type" is MANUAL. So I guess it's OFF until you turn it ON? Seems kind of strange to leave that up to the user but not really explain to anyone whether it's best on their system to enable or disable it. Weird.

I followed instructions to the link.
the results said there were currupt files found but could not fix. for anwsers it said go to logs using windir/CBS/CBS.log, how do I do that?
