Windows XP prefetch folder

All along, how to speed up the start-up speed of Windows XP is a topic of concern to the majority of users. The author in my long-term use of Windows XP (Chinese Professional Edition) in the process of accumulating some of the Windows XP system to speed up the method, now share out hope to help readers.

　　 first, and read the document said Bye-bye

Users familiar with the Windows XP startup process will know that the most important connection to the system startup speed is a prefetch folder in the Windows folder. This is a new feature that has been added since the start of the Windows XP operating system--pre-read. Microsoft's intention is to use the pre-read function to improve system performance, speed up system startup and file read speed. However, if you look carefully, you will find that the file will increase with the use of time, and are some files with the PF extension. This is because every time we start a program, Windows will leave an index in the Prefetch folder (similar to the Prolog folder in Windows98), and Windows XP will prefetch folder when it is powered on The common programs involved in reading memory (this process is the time period when the progress bar scrolls during startup). In this case, the system in the new installation when you may not feel very slow to start, but a long time, the prefetch folder in the production of read-only files, the system needs to start reading the content of the more complex, the system started to slow down is not surprising. So can you start with the Prefetch folder to speed up Windows XP? The answer is yes.

　　 1. Prohibit the production of index files

As we said above, the Prefetch folder is the index file (PF format file) that was left after the program was started. Therefore, we can effectively control the size of the Prefetch folder as long as we do not allow the system to automatically generate index files, so that it does not become a "scourge" that slows Windows XP startup.
Click start → run to open the System Configuration Utility by entering Msconfig and then enter. Switch to the Services tab and locate the Task Scheduler item. Task Scheduler can be said to be the "culprit" that produces the garbage index file, and when it runs in the background, it creates an index file for each program on our hard disk that starts with Windows and puts it into the prefetch folder. As long as we cancel the check on the item, we can "slim down" the Prefetch folder.

2. Set pre-read object

Because the Prefetch folder contains all the indexes that follow the Windows XP startup program, we can make certain settings so that the system reads only part of the content at startup and does not read the unspecified content. This can also effectively speed up the startup of Windows XP.
Click start → run, enter "regedit", open Registry Editor, and expand hkey_local_machine/system/
Currentcontrolset/control/session manager/memory management/prefetchparameters subkey, double-click the "EnablePrefetcher" key in the right window, You can open the edit window and pre-read settings for Windows XP. The pre read settings for the specific values are as follows:

0--cancellation of pre-read function;
1--only pre-read applications;
2--only read the Windows XP system files;
3--pre-read Windows XP system files and applications.
Here we can set this value to "2", which reads only the system files for Windows XP itself, ignoring the index files produced by other applications.

　　 3. Empty the prefetch folder

Because some applications and even system files produce dead link files in the Prefetch folder, this can exacerbate the burden of system prefetching at startup. And through the author's practice, the regular deletion of prefetch files in the folder can also effectively improve the system startup and running speed.
Step one: Create batch files
Create a new Notepad, where you enter the following:
Del%systemroot%\prefetch\*.*/Q and saves it as a Delpf.bat file.
Step two: Set up every shutdown to perform an empty operation
Click start → run, enter gpedit.msc to start the Group Policy window, expand Computer configuration → windows settings → script, and then double-click the Shutdown option in the right pane to go to the Shutdown Properties dialog box. Click the "Add" button to add the Delpf.bat file you just created to the shutdown task. In this way, the Prefetch folder is automatically emptied each time the shutdown occurs, and the next time the system starts, it does not require a pre read operation.

　　 second, avoid system invalid detection
Windows XP automatically detects hard disks on all IDE channels at startup. If some of the IDE channels do not exist, then the detection speed will become more slow, the system started naturally slowed down. In fact, if your IDE device stays the same for a long time, let's say you use only one hard drive, you can set the unused IDE channel to none, so that the system does not do useless testing on the IDE channel at startup, saving valuable startup time.
Right-click on "My Computer", select "Properties" → "Hardware" → "Device Manager", enter "primary IDE channel" and "Secondary IDE channel" respectively, in its property menu, change the device type not used to "none".

Of course, if you often replace IDE devices (often removed and added), then the above method does not apply.
Now most users use the broadband virtual dial-up software for dial-up operation after the network, so ISP broadband operators will automatically assign a temporary public network IP address, so do not need us to manually set the TCP/IP protocol binding to the network card. However, this also brings problems, Windows XP at startup will be the default search network DHCP to obtain IP address, but in fact, the user is not in the LAN, there is no DHCP server, so Windows XP Non-stop search will cause the system to start a delay. To do this we can use a method to specify an IP address for the NIC.
Open Control Panel → network Connections, select the Local connection icon for the current network card, right-click on it, and select Properties. In the Settings window that pops up, select Internet Protocol (TCP/IP) → properties to turn on the TCP/IP Settings window. Select "Use the following IP address", and add a fixed intranet IP address for the network card, such as 192.168.1.1, and then reboot the system will not be in the search network, starting speed is greatly improved.

ThreeUse the Boot accelerator patch Bootvis
Bootvis is a special hotfix that Microsoft offers to speed up Windows XP startup. Using it to optimize the system can also speed up the startup.
Download Address: Http://crc.onlinedown.net/down/bootviscn.exe
Unzip the download file to find the Bootvis program, double-click to start, click Options on the Tools menu, specify the path to the Bootvis program in the Symbol box, and click the "Save" button. Then, after selecting track → next boot on the menu bar, click OK. At this point the Bootvis program restarts the computer and logs the startup process to generate a record file with the name extension bin. After entering the system, Bootvis will run automatically. We simply click the Make System Optimization command on the trajectory menu to complete.


Tip: Because Bootvis needs to rely on the Task Scheduler service to work properly, if you use Bootvis you need to turn on the Task Scheduler service that is disabled in the previous method one to function properly.
