Windows XP effectively reduces startup time

Although the saying goes, "There is a cure for serious illnesses," but the bugs have always believed that everything must be fruitful. The remedy is to cure a serious disease, and there must be rules to follow. In this column, the worms talk about the various "rules" that are circulated on the rivers and lakes in a scientific attitude of seeking truth from facts. If you can cure the disease, the worms will recommend it; if there is no effect, the worm will be debunked. It is not that the worm does not understand that the world is changing fast. Especially for things related to computers, the update is even faster. In a blink of an eye, Windows XP has entered thousands of households. Bugs think Windows XP is really good, it is too slow to start.

A few days ago, a remedy that claimed to be able to “speed up the startup speed” caused the interest of the worm: “Open the registry and find the Prefetch Parameters subkey branch in the registry editor. The key value of the Enable Prefetcher key item is changed from the default & lsquo; 3 & rsquo; to & lsquo; 1 & rsquo;, restart the computer, is it a lot faster? ”

The bugs immediately queried Microsoft's technical documentation. The setting parameters for "Enable Prefetcher" are as follows. 0: Disable pre-read; 1: Pre-read application; 2: Pre-read system files; 3: Pre-read system files and applications (system default settings). This makes the worms very unpredictable.

Literally, "Prefetcher" should be set to improve performance. Why can it be enabled to increase it?

The worm is a real person, and immediately experimented with a computer in the office. As a result, it was found that, contrary to the "prescription", when the Prefetcher value was changed from 3 to 1, not only did not accelerate the startup, but the startup time was extended by 20%!

At the same time, this experiment also allowed the bug to find a trick: periodically delete the pre-read files in the pre-read folder (c:\\windows\\prefetch)”, which can effectively speed up WinXP. Start time.

In addition, Microsoft has also provided a patch called BootVis to speed up WinXP startup. Start BootVis, click on the “Tools” menu"Options”, type the path of the BootVis program in the "symbol" box, and click the “Save” button. Next, in the “Trace” menu, click ““NextBoot”, and then click the “OK” button. At this time, the BootVis program will boot WinXP to restart, and record the startup process to generate the relevant BIN file. After restarting, BootVis is still running. In the <quo;Trace" menu, click the <quo;Optimize system” command.
