Solve the problem of Win7 mouse wake and video acceleration CPU occupancy

First, the control of the Windows 7 system leaving mode

Users who are familiar with Windows 7 and Windows XP should know that Windows 7 has a more than Windows XP exit mode in power management (what is Exit mode?). When the user has left mode enabled, you can let Windows 7 implement the "Sleep Download" feature. But in many cases, because you or someone else doesn't mind moving the mouse, Windows 7 will wake you up from a deep sleep. As we all know, the departure mode from the Vista system began to exist, Win8, Win7 under the model.

In many cases, users want the computer to sleep in the wrong click and move the mouse do not wake up the computer, then how to allow the user to move the mouse, but does not affect the Windows 7 in use leaving mode (meaning that only the keyboard to wake windows 7)?

In fact, we can go to Windows 7 Control Panel, locate and click Device Manager, right-click the unit price "mouse and other pointing device" in the open window, and select Properties.

At this point, the System opens a dialog box again, switch to the Movie Management tab, and then cancel the allow this device to wake the computer by default check system.

When you cancel this check box, you don't have to worry about the mouse malfunction and wake the computer.

Whether you use the Win7 optimization master or the Rubik's Cube optimization master, you can easily find out the setting option of leaving mode in the system master

Second, let's take a look at the phenomenon of video acceleration causing excessive CPU:

Under Windows XP system, many users turn on the WINDOWSX Media player (hereinafter called WMP) Player's video acceleration function, in this way, can be a part of the old video card to better high-definition playback effect. When the operating system to Windows 7 o'clock, the vast majority of users of the hardware environment, has been able to respond well to the needs of high-definition playback, therefore, the role of Windows XP video acceleration function, now a bit outdated.

When Windows 7 users use WMP 12 to play high-definition video files, they often find that CPU usage is high, or even 100% occupancy, possibly because WMP 12 turns on the video acceleration feature. Video acceleration, in the Windows XP era has some practical significance, but now can run the hardware environment of Windows 7 smoothly, basically can meet the needs of high-definition playback, so we can shield it to save system resources.

Run WMP 12, click tools → options, switch to the "Performance" tab in the pop-up dialog box, and cancel the "DirectX Video acceleration for WMV files enabled by default" of the program, as shown below:

After the modification is complete, save the settings and exit.

As hardware is being updated and developed, some of the previous features that can function in Windows XP systems have been gradually lost in the Windows 7 system. Users in the actual use of the process, can be based on the actual situation to choose and save system resources.
