The trouble is that it will only help you for a while – until the
prefetch gets clogged up again. We need to edit a registry key to tweak
it. Open regedit and browse to this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session
Manager\Memory Management\PrefetchParameters

Under this key you should see a value named: EnablePrefetcher

It has 4 possible values:

0 – Disabled : The prefetch system is turned off.

1 – Application : The prefetch only caches applications.

2 – Boot : The prefetch only caches boot system files.

3 – All : The prefetch caches boot, and application files.

We don’t want to disable it entirely. This would actually make boot
times *longer*. This is because this feature is also used to speed up
the loading of boot files. That is why we are going to pick the number 2
option. It allows us to keep the advantage of caching system files,
without continually clogging the system up with applications.

Set the value to 2 and reboot.

The 2nd time you boot it should boot much faster. Remember that the side
effect is that launching individual applications once windows has loaded
will now be slightly slower.


PS: when using regedit, just search for EnablePrefetcher.

The rest of that long string is made up of section names and does not
exist as a search term.
