When you say "deactivating Superfetch service" are you talking about disabling the service or using the registry tweak? In my experience simply setting the service to disabled produced a lot of HD activity after the desktop comes up whereas setting it to only cache boot files seemed to work best. Manually stopping it works too but you have to remember to do it or set up some kind of task to do it so many minutes after boot.

It's weird because my machine will go for days with an empty file in ReadyBoot folder, then just last night it decided to churn for awhile and now I have a 20 MB file there.
Seems a bit unpredictable.

Hi Brink.

Unfortunately your .reg file didn't work for me so I decided to do things the manual way.

I don't have a controlset 001. I have 002, 003 and 005

I have changed the parameters in each of these for Boot Files only. Is this OK?

Hello Beauparc,

I have updated the tutorial to have it work correctly for you this time. Try it again. The controlset ### are backups, it should have been written to CurrentControlSet instead.

Hmmmmmmm it is a strange beast! I had a 0 length ReadyBoot.etl file and as soon as I deleted it, bang! A 20 MB file was written there!! It was instant! Maybe the file already existing kept it from writing? Weird!

Yeah, the prefetch shouldn't change much with just the boot files since they usually do not change often.

LOL, you can't fix it unless you break it though.

I have Crawl Start Pages instead, wonder if that's the same thing.

Hi CGA, and welcome to Vista Forums.

I also have CrawlStartPages in the Shell folder, but I'm not sure if it is or not. I suppose it could be language translation thing.

Thanks Brink, great forum btw. Guess i'll disable CrawlStartPages and see if i notice any difference.

Your welcome CGA. Let us know how it goes.

Thank you,
