Well, when you install system the prefetch will be very very full of windows stuff. Like over 50-70 prefetch titles are from vista alone and I doubt anyone uses everything Microsoft design in their systems. So Basically getting this fixed would be easily done by deleting .pf Files (default: C:\Windows\prefetch)after sometime from Windows Vista Installation & usage. Windows will correct this issue when there is upcoming optimizes in Vista as in vista will run after some Idle period this tool rundll32.exe which collect and optimizes entire harddrive accordingly to layout.ini & prefecth (Order: boot files->Application Files-> rest of HDD by date modified).

After that tasks has runned 5 times (manual task launching commandline: rundll32.exe advapi32.dll,ProcessIdleTasks ) Vista also does another sort of optimize to system. It compresses almost all the system data you haven’t needed so far in vista and eventually system takes less space in your root harddrive.

Now about prefetch.. Superprefetch was as far I know designed for Software you use not for boot files to check why normal prefetch removes some application when it gets full and readds that application in the ‘\windows\prefetch’ folder. This is good if it would actually just work on applications. It is very well functioning system I have no doubt on that, but what if you made normal prefetch only work for boot and leave Superfetch to Applications only. Anyhow tested this here now for a week and system is faster than before alot on booting and on usage.

Original Windows Vista settings by default:

The way I was talking about [prefetch=boot, Superprefetch=Apps]:

Anyhow, some high tech can put nail in to head anytime on this one, but just saying this after week of usage. More than 100 Softwares installed.
