Learn to quickly defragment Win7 disk fragments in one minute

Windows operating system has the function of disk defragmentation, but people have the impression that the defragmentation process of the previous Windows operating system is very long, but Win7 is different, and the previous versions of the operating system Compared to a big improvement. Previous versions of the Windows system defragmentation function always need to right-click on the disk, and then select Properties in the pop-up menu before calling the Disk Defragmenter. Now in Windows 7, we can make your defragmentation more convenient with a little trick, put the defragmentation function directly into the right-click menu, and let Windows 7 quickly execute the defragmentation command at any time. How to do it? One minute to teach everyone.

Before I do, I think I should tell you more about the origin of disk fragmentation. In fact, disk fragmentation should be called file fragmentation. This is because user files are not continuously saved on disk, but are scattered. Saved to different areas of the entire disk. When the physical memory required by the application is insufficient, the general Windows operating system generates a temporary swap file on the hard disk, and the hard disk space occupied by the file is virtualized into memory, and then the virtual memory management program frequently reads and writes the hard disk. This produces a lot of debris. In addition, web browsers that are essential to everyone's computers will also generate a large number of temporary files or temporary file directory settings when you use the Internet to browse. Usually, these file fragments will not cause system use problems, but too much fragmentation will increase the burden of the system to read and write files, so that the performance will be degraded, sometimes causing file loss, and in serious cases, the life of the hard disk will be affected. . Therefore, it is very important to defragment the disk at regular intervals.

Microsoft provides a more efficient defragmentation tool for the Windows 7 operating system, but each time you start it you need to go to the "All Programs" option in the Start menu under the "Options" option. It can be found in the tool, it seems a bit too much trouble. We can simply modify the Windows registry to add the defragmentation function to the right-click menu of the disk. Right click on any disk and you can perform the operation immediately.

First, press the Windows key + letter < R & rdquo; call out the stand-alone window, type the “ regedit & rdquo; command to open the registry editor, then find HKEY_CLASSES_ROOT\\Drive\\shell, then in the left panel Create a new branch, named runas; change the Default value in the right panel to Defragment, and then create a new key named Extended in the right panel. Now go back to the Disk Management window and right click on any disk. You will see the Defragment item in the pop-up menu.

Most computer users who use Windows systems know that the system needs to be defragmented after using it for a period of time. Otherwise, it will affect the system running speed and reduce the working efficiency of the hard disk. For this reason, I would like to remind the majority of users, because this operation involves the registry modification, if you are not too familiar with this operation, it is best to do a backup before starting, just in case.
