Prefetch is a pretty cool feature that started with Windows XP, was improved in Vista and even more optimized in Windows 7. There are two primary functions provided by the Prefetch system both designed to speed up your boot and recover time.<\/p>\n<p><a href=\"http:\/\/www.billp.com\/blog\/images\/WindowsPrefetchSuperFetchControversy_F611\/prefetch.jpg\"><img fetchpriority=\"high\" decoding=\"async\" style=\"border-bottom: 0px; border-left: 0px; display: block; float: none; margin-left: auto; border-top: 0px; margin-right: auto; border-right: 0px\" title=\"prefetch\" border=\"0\" alt=\"prefetch\" src=\"http:\/\/www.billp.com\/blog\/images\/WindowsPrefetchSuperFetchControversy_F611\/prefetch_thumb.jpg\" width=\"240\" height=\"279\" \/><\/a> <\/p>\n<p>The first methodology used by Prefetch is to tell Widows which programs or code segments are commonly used at startup by multiple programs or processes. Instead of the having Windows load the same code segment multiple times, it\u2019s loaded once and available for all the programs who use it.<\/p>\n<p>The second focus of Prefetch is to help the disk layout of programs which are commonly loaded at startup. Window keeps track of commonly loaded programs and will check how these programs are stored on your hard drive or other storage device. If needed, the disk will be de-fragmented and organized during idle time so that the programs are easily accessible at boot time. This information is stored in a text file layout.ini found in the prefetch folder.<\/p>\n<p><a href=\"http:\/\/www.billp.com\/blog\/images\/WindowsPrefetchSuperFetchControversy_F611\/layout.jpg\"><img decoding=\"async\" style=\"border-bottom: 0px; border-left: 0px; display: block; float: none; margin-left: auto; border-top: 0px; margin-right: auto; border-right: 0px\" title=\"layout\" border=\"0\" alt=\"layout\" src=\"http:\/\/www.billp.com\/blog\/images\/WindowsPrefetchSuperFetchControversy_F611\/layout_thumb.jpg\" width=\"244\" height=\"183\" \/><\/a> <\/p>\n<p>Other memory optimization information is stored here and used by Windows to decide which code segment should be in active memory and what can be cached. Under Windows XP, many background programs like virus scanners which aren\u2019t common startup programs may get more attention than they deserve. While it\u2019s been fixed starting with Vista, it can still be a problem under Windows XP.  If this becomes a problem the solution is a simple reboot. There has always been the controversy over keeping your computer on over night or to reboot each day.  I now recommend occasional rebooting which will also help refresh the Prefetch information.<\/p>\n<p>The Prefetch folder is another good reason to keep your list of auto startup programs to a minimum. Using programs like <a title=\"http:\/\/www.winpatrol.com\/\" href=\"http:\/\/www.winpatrol.com\/\" target=\"_blank\">WinPatrol<\/a> can clean up which programs are auto started and thus stored in Prefetch. Adding WinPatrol PLUS will help you decide which programs are really required.<\/p>\n<p><a href=\"http:\/\/billpstudios.blogspot.com\/2009\/10\/faster-startup-with-windows-prefetch.html\" target=\"_blank\">Should You Delete Prefetch Files? &#8230; Article Continued Here<\/a><\/p>\n<p>This post is excerpted with Bill&#8217;s permission from his <a href=\"http:\/\/billpstudios.blogspot.com\/\" target=\"_blank\">blog<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><img decoding=\"async\" src=\"http:\/\/techtalk.pcpitstop.com\/wp-content\/uploads\/billpwp.jpg\" alt=\"bill p\" class=\"attachment wp-att-7167 alignleft\" \/><\/p>\n<p>By Bill Pytlovany<\/p>\n<p>Earlier this month I had a huge reaction to my post <a href=\"http:\/\/techtalk.pcpitstop.com\/2009\/09\/28\/bits-from-bill-most-underated-free-tweak-to-improve-windows-performance\/\">about cleaning up the Windows \u201cTemporary Internet Folder\u201d<\/a>.
