Looks like the Admin has fallen for a myth. This myth that deletion of prefetch files is beneficial is based on a complete misunderstanding of how prefetch actually works. Prefetch does not preload applications or any portion of them at bootup. Application prefetch files are not even referenced until the application is launched. At this time they are used to optimize the launch time of the application. Prefetch files NEVER cause an application to be loaded. In any event the prefetch folder is self cleaning after 128 entries. All of this has been extensively tested. Manual deletion of prefetch files will deprive Windows of a valuable resource and has no benefits. If this actually improves boot time this is a clear indication that the system has problems. The proper procedure would be to diagnose and correct the problem.

Unused prefetch files do nothing but take up a small amount of disk space and are automatically cleaned at 128 entries down to the 32 most used app's prefetch files by Windows. Cleaning the folder manually will cripple all applications and windows load times.<br/><br/><a HREF="http://mywebpages.comcast.net/SupportCD/XPMyths.html" REL="nofollow">XP Myths</a> Cleaning the Prefetch folder is a Myth and will REDUCE performance.
