Use Win XP/2003 to pre-read files Keep system performance optimized

It is understood that by default Windows XP/Server 2003 only pre-reads Windows system files. For those who don't have a high computer configuration, they may want to cancel the pre-reading function. For a friend with a high computer configuration, they may want to pre-read some files. How can we create a pre-reading method that suits you?

The Windows\\Prefetch folder under the Windows XP/Server 2003 system disk is the pre-read folder, and there are many files with the PF extension in the Prefetch folder. This is System-generated pre-read files. However, if this function is not used well, it will generate a large number of pre-read files for a long time, occupying valuable hard disk space, causing the system search to take longer, increasing the burden of system search and making the system run slower.

In fact, Windows XP/Server 2003 allows us to change the pre-reading method and set the pre-read object by ourselves. To do this, click on "Start → Run", enter "Regedit" in the Run dialog, open the Registry Editor, expand the HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\PrefetchParameters branch, and find The "EnablePrefetcher" in the right window is the pre-read mode of Windows XP/Server 2003 controlled by this key. Double-click on “EnablePrefetcher” to open the “DWORD” value edit window and pre-read the windows xp/Server 2003 by changing the value of “Value Data”.

Set “Value Data” to:

“0”——Cancel the pre-read feature;

“1”—— The system will only pre-read the application;

“2”—— The system will only pre-read Windows system files, this is the default setting of windows xp/Server 2003;

“3”—— The system will pre-read Windows system files and applications.

Ok, now you can define your own pre-reading method based on your computer configuration.

Secondly, we have to develop a good habit of regularly cleaning up pre-read files. You can manually delete all the files in the Prefetch folder at intervals. In this way, the pre-reading function of the system can better serve us.
