How to effectively shorten the startup time of Windows XP

Although the saying goes that "there is a big cure for the disease", the insects still believe 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. 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 "accelerate the startup speed" caused the interest of the worm: "Open the registry, find the Prefetch Parameters subkey branch in the registry editor, and the key value of the Enable Prefetcher key item on the right side. The default '3' is changed to '1', restarting the computer, is it a lot faster?” The bug 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 disabled to increase the startup speed? The worm was a real person, and immediately experimented with a computer in the office. 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 files in the "pre-read folder (c:\\Windows\\prefetch)", which can effectively speed up the startup time of WinXP. In addition, Microsoft has also provided a patch called BootVis to speed up WinXP startup. 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.
