Delete read-ahead files to increase system speed

After using Windows XP for a long time, you will find that the system is running at a slower speed. You can't solve the problem by using multiple optimization software and uninstalling the installed software. The culprit is the read-ahead setting. There are many files with PF extension in the “Windows\\Prefetch” folder. This is the pre-read file. If you empty the file, you will find that the system running speed is back to normal! It seems that the pre-reading settings can increase the speed of the system, but after a period of use, the files in the pre-reading folder will become much more, and the time it takes for the system to search becomes very long. Moreover, some applications generate dead link files, which increases the burden of system search. Therefore, we should periodically delete these pre-read files to increase the boot speed.

Of course, Windows XP resets the read-ahead object is allowed. 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-read the Windows XP:

Set the value to "0" to cancel the pre-read function; set to "1", the system will only pre-read the application; set to "2" The system will only pre-read the Windows system files; set to "3", the system will pre-read the Windows system files and applications. Generally, we can set the value to "2". Of course, if your computer is configured very high, if you change the value data to 4 or 5 using the PIII 800MHz CPU or above, you can also leave the value data as the default value. . This will speed up the system.
