Windows 7 system commands to help you accomplish very tasks

Use of the command will undoubtedly improve the efficiency of system management. In addition, the use of hidden parameters in the command can be implemented in some graphics interface can not be easily implemented tasks. A significant number of command tools have been integrated into Windows 7, and these tools are powerful weapons for our system management. The following is a list of several command-line tools in Windows 7 that you can use to achieve faster system administration tasks.

1. Remove the useless power management scheme with POWERCFG

With the power Management console for Windows 7, we can create our own power management scheme as needed, but the console does not provide power scheme deletion. How do we remove the power solutions that we don't need? At this point everyone can powercfg the command to achieve.

Powercfg.exe is a power management command to introduce Windows systems from Vista, and you can enter "powercfg/?" at the command line. To view the parameters and instances of the command. The command format for removing the power scheme is "Powercfg-delete", where the GUID is the identifier for the power management scheme and we can execute the command "powercfg-list" to get it. As shown in Figure 1, if we want to remove the Power management scheme named JP, execute the command "Powercfg-delete 53d4577a-49c1-4867-ba59-7fd20316fa2d". (Figure 1)

2, use Defrag to speed up the defragmentation of disk

Defrag.exe is a Windows integrated Disk Defragmenter that provides additional parameters to the Disk Defragmenter tool for Windows 7 compared to Vista, which allows us to have more control over disk defragmentation. Here I would like to introduce you to a few interesting parameters:/r parallel processing of multiple drives, can be implemented at the same time to defragment multiple drives;/h lets Disk Defragmenter use more system resources to speed up operations (usually we do disk defragmentation during system idle time, This option speeds disk defragmentation, does not compete with other applications for system resources, and U provides a regular progress report, and we can see the detailed process of defragmenting to understand the disk fragmentation status. Like we execute the command "defrag/c/h/u/R" can quickly organize multiple drives in one command-line window. Of course, Defrag has other parameters, open to execute "defrag/?" at the command line. To get. (Figure 2)
