Shorten Windows XP startup time

Although the saying goes, "folk prescription for big disease", but the worm still always believe that everything will have fruit. The folk prescription is to cure the big disease, among them also must have the law to follow. In this column, the worm in the scientific attitude of seeking truth from facts, talk about the various "folk remedies" on the rivers and lakes. Really can cure, bug makes great recommendations, no effect, bug resolutely puncture.

Not worms don't understand, the world is changing fast. Especially with computer-related things, updated faster. In a blink of an eye, Windows XP has entered thousands of households. Bugs think that Windows XP is really good, the speed of startup is too slow.

A few days ago, a claim to "speed up the start speed" of the folk prescription caused by the worm's interest: "Open the Registry, in Registry Editor to find the Prefetch Parameters subkey Branch, the right enable Prefetcher key value keys from the default ' 3 ' Change to ' 1 ', restart the computer, is not a lot faster? ”

Bug immediately inquires Microsoft technical document, regarding "Enable prefetcher" the setting parameter has the following several. 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 worm very puzzled.

Literally "Prefetcher" (prefetching) should be set to improve performance, why disable it instead to improve the startup speed?

Worm is a real person, immediately took a computer in the office to do the experiment. The results found, precisely and "folk prescription" in the contrary, when the Prefetcher value from 3 to 1, not only did not accelerate the start, but let the start-up time extended 20%!

At the same time, the experiment has found a trick: periodically deleting the c:\windows\prefetch files in the pre-read folder, which can effectively speed up the WinXP startup time.

In addition, Microsoft also specializes in providing a hotfix Bootvis to speed up WinXP startup. Start Bootvis, click Options on the Tools menu, type the path to the Bootvis program in the Symbol box, and click the Save button. Next, on the Trace menu, click Nextboot, and then click OK, at which point the Bootvis program will boot WinXP and record the startup process and generate the associated bin file. Bootvis is still running after reboot, on the Trace menu, click the Optimize System command.
