"SUPERFETCH" Tweak... Anyone tried it?

????

I'm reading other people claiming their XP Pro PCs start in half the time, and any Windows Explorer function happens instantly (Clicking the start menu if you have a million things in it, for example, or loading a lot of Explorer windows)

Also, apparently browsers load instantly now.

Sounds almost too good to be true.

I thought this was for Longhorn and also a reason why the os needs more system memory.

The only reason why its faster is they added a superfetch feature to the prefetcher. If you look at the key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\Prefetcher

you will notice in windows xp

EnablePrefetcher = 3 and you will notice in windows longhorn
EnableSuperfetch = 1

Well, guess what? You can put the EnableSuperfetch = 1 in windows xp and get the same speed

I tired it and got no difference in performance. Altho my registry doesn't have that exact string, istead of Prefetcher at the end it has PrefetchParameters. I added the DWORD valuve of EnableSuperfetch and 1 in first hexidecimal and then tried it in decimal. Nothing changed.

Every site and forum I've read has been the same stuff:

No changes noticed.

But in every thread, there are two or three clowns who say, "Dude! My XP boots up in half the time, and I can load programs instantly now!"

TheInquirer reported this, but on the same page they have a fake news story. I don't now if this is real or not.

Hahaha! Sounds like someone we know.

The Inquirer is hardly an accurate news source. I rate it somewhere below Fox news and somewhere above the Church of Scientology's monthly news flyer.
