【 Weak current College 】 modified XP prefetch files to speed up system startup

With Windows system body growing, WindowsXP, Microsoft provides a read-ahead. That is, in the Windows folder added a Prefetch folder in order to use this feature to improve system performance, speed up system startup and file reading speed. However with the increase in the use of time, each using a program, the system folder in the left one to PF for the extension of the index file. Prefetched file causes the system to start slow, because when you run the program you want to read the generated index file. Therefore, we only need to suppress the generation of PF file.

In the "run" window, enter "msconfig" carriage-return opens the system configuration utility window, switch to the "service" label, then the "TaskScheduler" item before hook cancel and save the settings so that you can play against the purpose of establishing the index file.

Second, only read system files

Since the Prefetch saved system and application of index information, improve boot speed point of view you can only set the read system files, skip the application process for the index file read. To do this, you can run "regedit" to open the registry editor, select HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters, double-click the right side of the "EnablePrefetcher", you can see that the value is 3, i.e. read system files and applications, we can change it to 2, that is, only Windows system file read-ahead.

Third, the shutdown automatically empty prefetch files

We can also shut down automatically empty prefetch folder content to speed up the next time you boot speed. Open Notepad, enter inside del% systemroot% \Prefetch\/q *. *, save the file as file del.bat. Next, and then open the "run" window, enter gpedit.msc after carriage return to open Group Policy Editor, select the "computer configuration-Windows settings — script", double-click on the "shutdown" to the right, inthe opened window click the "add" button to add the file del.bat. This group policy at shutdown is called del.bat in the background and run commands on the prefetch folder content is clear, which increases the speed of the next time you start.
