Have you noticed the Windows XP read-ahead settings?

I have been using Windows XP for more than a year. Recently, I found that the system is running at a slower speed. Using a lot of optimization software and uninstalling the installed software will not help. In order to find out the crux of the problem, the author first looked at the disk space in the area where Windows XP is located, and found that the Windows folder takes up a lot of space. The author then went to the Windows folder to see if there were any strange files. When I looked at the "Windows\\Prefetch" folder (that is, the Windows Read-Ahead folder), I found that there are hundreds of files with the PF extension. I can’t help it. One move: Is it its problem? Try to empty the files inside, restart the computer, and find that the system is running at a normal speed!


original, pre-read settings can improve system speed though, but after some time, the prefetch folder of files will become much, causing the system to search it takes longer. Moreover, some applications generate dead link files, which increases the burden of system search. Therefore, we should delete these read-ahead files on a regular basis.

Of course, Windows XP also allows us to set up pre-read objects. To do this, open the Registry Editor, expand the HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\PrefetchParameters branch, and double-click EnablePrefetcher in the right window. In the Open DWord value edit window, you can Pre-reading settings for Windows XP:

Setting this value to "0" means canceling the pre-reading function; setting to "1", the system will only pre-read the application; set to "2", The system will only pre-read Windows system files; set to "3", the system will pre-read Windows system files and applications. Generally, we can set the value to "2". Of course, if your computer is configured very high, you can also set the value to "3" to speed up the system.

We can also make a batch program ourselves, delete the file of the "Windows\\Prefetch" folder every time you turn it on, for example, we create a new file named DelPre.bat, and then open it with Notepad. Add the following:

del %SystemRoot%\\Prefetch\\*.* /q

Adding the "/q" parameter is to remove the global wildcard, no confirmation is required, of course, other parameters can be used. For example, the "/f" parameter is forcibly deleting read-only files. Then save the file and remember to select "All Files" in the "Save as type" of the save dialog. Place it in the startup group.
