Let your XP start like flying

. Although the saying goes, "There is a big cure for the disease," but the worm still believes 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 "prescriptions" circulating 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.

not Bugs do 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. The bug thinks that the windows xp function is really good, that is, the startup speed is too slow.

A few days ago, a remedy that claimed to "accelerate the startup speed" caused the interest of the worm: "Open the registry, find the Prefetch Parameters subkey branch in the registry editor, and turn the Enable Prefetcher key on the right. The key value of the value item is changed from the default '3' to '1'. Restart the computer. Is it faster?"

The bug immediately queried Microsoft technical documentation about "Enable Prefetcher". The setting parameters 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" (pre-reading) should be set up to improve the performance, why disable rid of it but can improve the startup speed?

Bugs is an honest man, and immediately take a computer in the office to do the experiment. It turns out that, contrary to what is said in the "prescription", when the value of Prefetcher is changed from 3 to 1, not only does not accelerate the startup, but the startup time is extended by 20%!

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

In addition, Microsoft also offers a special program for accelerating BootVis WinXP patch started. Start BootVis, click "Options" in the "Tools" menu, type the path of the BootVis program in the "symbol" box, and click the "Save" button. Next, in the "Trace" menu, click "NextBoot", then click the "OK" button, then the BootVis program will boot WinXP restart, and record the boot process, generate the relevant BIN file. After restarting, BootVis is still running. In the "Trace" menu, click the "Optimize system" command.
