XP pre-read file for shutdown acceleration

As the size of the Windows system grows, Microsoft offers a pre read feature in Windows XP. http://www.aliyun.com/zixun/aggregation/32995.html > Adds a prefetch folder to the Windows folder to use this feature to improve system performance Speed up system startup and file reading. However, with the increase in the use of time, each user using a program, the system will be in the folder to leave a pf extension of the index file.

Prevent the program from producing index files

Pre-read files cause system startup to slow because the index files generated when you run the program are read. Therefore, we only need to prohibit the production of PF files.

When you enter "Msconfig" in the Run window, return to the System Configuration Utility window, switch it to the Services tab, and then cancel and save the settings before the "task Scheduler" item in it, thus preventing the indexing file from being established.

Second, read only system files

Since the index information of the system and application is saved in prefetch, from the point of view of increasing the boot speed, the Starling Network (http://www.it8g.com) reminds you that you can only set the read system files and skip the index file reading process of the application. To do this, you can run "regedit" to open Registry Editor and select HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\prefetchparameters, double click on the right side of "Enableprefetcher", you can see that its value is 3, that is, read system files and applications, we can change it to 2, that is, only pre-read Windows system files.

Third, the shutdown automatically empty the pre-read files

We can also automatically empty the contents of the read-only folder by shutting down the machine, so as to speed up the next boot. Open Notepad and enter del%systemroot%\prefetch\*.*/q inside to save the file as a Del.bat file. Next, open the Run window, enter Gpedit.msc, turn on the Group Policy Editor, select Computer Configuration reinstates Settings-script, double-click the "Shutdown" item on the right, and click the "Add" button in the open window to add the Del.bat file. In this way, Group Policy calls the Del.bat in the background and runs the commands to clear the contents of the read-only folder, thereby increasing the speed of the next boot.

Through the above operation, I believe that the pre-read file to play its original function, no longer become a barrier to boot. In addition, in Windows XP, you can also read the http://www.it8g.com/XiTong/200808/199.htm of the method described in the article to fully understand the failure of the XP down the handling method.
