Improve the pre-read file in the XP system to speed up on/off

I. Prohibit the program from generating index files
Pre-read files cause system startup to slow down because you want to read the index files generated when running the program. Therefore, we only need to disable the generation of PF files.

Enter "msconfig" in the "run" window and press enter to open the System Configuration Utility window and switch it to the "service" tab, then, deselect the check box before the "Task Scheduler" item and save the settings so that the index file cannot be created.

2. Read Only system files

Because Prefetch stores the index information of the system and application, we recommend that you read system files only and skip the index file reading process of the application from the perspective of improving the startup speed. In this regard, you can run "regedit", open the Registry Editor, and select "manage ManagerMemory ManagementPrefetchParameters", double-click "EnablePrefetcher" on the right side, and you can see that the value is 3, which reads system files and applications, we can change it to 2, that is, only pre-read Windows system files.

Iii. automatically clear pre-read files after Shutdown

We can also automatically clear the pre-read folder content at shutdown to speed up the next boot. Open notepad, enter del % systemroot % Prefetch *. */q in it, and save the file as a del. bat file. Next, open the "run" window and enter gpedit. msc, press enter to open the Group Policy Editor, select "Computer Configuration-Windows Settings-script", double-click "shutdown" on the right, and click "add" in the window that appears, del. add the bat file. In this way, the Group Policy will call del. bat in the background and run the command to clear the content in the pre-read folder, thus improving the next Startup speed.

Through the above operations, I believe that the pre-Read File only uses its original functions and is no longer an obstacle to boot.
