That's only for Vista. That key has no effect on Windows 7, it is ignored and provided for backwards compatibility. 7 will always cache both boot+user binaries as it sees fit. There's a big MSDN blog article about Windows 7's Superfetch they mention it there.



The EnablePrefetcher key is only in XP because in Vista the Prefetch Driver was replaced with the Superfetch service. Again, only there for backwards compatibility. But from memory, Vista will actually change this reg value depending on Superfetch service state - so that older pre-Vista software can still test if 'Prefetching' is enabled or disabled - when it's actually checking Superfetch status.

P.S. That first one is a BitAND - 1 is probably "cache boot", 2 would be "cache user apps" so 2+1 = 3 = do both. 0 is do none.

Are there any news on this topic?

Did anyone manage to test and see if superfetch could be added back to 2008 r2, and if it did work?
This topic have been quite silent for a long time.

I am two thirds through comparing all the differences between a Win7 and R2 installation (registry and file differences) and already found some Superfetch/Readyboot information that is missing from previous installers in the thread though I'm unsure if they're needed yet.

So yeah I guess there is news I'm still working on getting my ReadyBoost for R2 (you need SuperFetch for ReadyBoost) and will have it all in one package when I nail it.

Thanks for the reply, I hope you are doing great progress with the comparison between windows 7 and 2008 r2. Its such a great feature in windows 7 (and vista), too bad its not easier implemented in server 2008.

Yeah, I managed to get ReadyBoost in 2K8 but that had SuperFetch as an addon module, so it wasn't as hard. There's all drivers and junk in Win7/R2

That sounds good you made progress already.
Its just too bad MS made it harder than in 2008. Would make 2008 even more attractable as a workstation compared to win7.

try to use eboostr which was posted by a member of this forum - I really like it

Hello,
Any news on how to make SuperFetch work under R2 ?

Great work, Thanks!

I have SuperFetch sort-of working but would like to cross-check everything with the other guys before I release for testing.

AsciiWolf and GnatGoSplat - could you guys release your work so far (4shared link is dead) so I can make sure all our work is inclusive

Sorry, I don't have my installer anymore... I got new HDD and forgot to back-up some data including my Superfetch installer...
