Superfetch?

[Kaunisto]

Internet seems to be undecided on whether turning off Superfetch (in my case Windows 7) is a good or bad idea.
Any of you have any insights/experience on this?

Also, my error reports show that Superfetch has stopped working several times per day for couple weeks now (having never happened before in 5 years). What could cause that?
I don't remember having installed anything at the time or making any changes to Windows settings.

Looks like turning it off shouldn't really hurt (aside from making things slower to start). So not so much a good or bad idea as just and idea

Got any logs or something to go with that?

Looks like crashes are all about the same:

Having had Superfetch off for a day now - and I'm not sure if I've ever before turned it off - so far the only notable change is that harddrive isn't constantly doing something like I'm used to. But I haven't done anything to really test the computer, to be seen in couple days what happens with a new game (I always start some games at new year's day).

A search tells me c0000005 is an access violation which would normally mean someone made a programming mistake. Seems a bit unlikely if it's only recently started doing that though - assuming it didn't get updated somehow.

You DO NOT NEED it, and neither does Windows.
