Solve the problem of excessive CPU usage due to mouse wakeup and video acceleration under Win7

Why is the CPU usage so high when using the mouse to wake up the system under Win7? Why is the CPU occupied by Windows Media Player in video acceleration mode? Is this all for shrimp?

First, to control the exit mode of Windows 7 system

Users familiar with Windows 7 and Windows XP should know that Windows 7 has a more exit mode than Windows XP in power management. Is the departure mode?). When the user enables the leave mode, you can let Windows 7 implement the "sleep download" function. But in many cases, because you or someone else doesn't move your mouse, Windows 7 will be awakened by your sleep. As everyone knows, the exit mode has existed since the Vista system, and this mode is available under Win8 and Win7.

In many cases, users want the computer to accidentally click and move the mouse during sleep. Do not wake the computer, so how to allow the user to move the mouse without affecting the leaving mode of Windows 7 in use (ie Only allow the keyboard to wake up Windows 7)?

In fact, we can enter the Windows 7 control panel, find and click "Device Manager", right-click the unit price in the open window "mouse and other pointing devices", select "ldall" attribute & rdquo; .

At this point, the system will open a dialog box again, please switch to the "Movie Management" tab, and then cancel the system default checkmark "Allow this device to wake the computer" ;

After canceling this checkbox, you don't have to worry about the mouse malfunctioning to wake up the computer.

Whether you use Win7 optimization master or Rubik's cube optimization master, you can easily find the setting mode of leaving mode in the system setup master ——

Then let's take a look at the phenomenon that video acceleration causes the CPU to be too high:

Under Windows XP, many users have turned on the video acceleration function of Windowsx Media Player (hereinafter referred to as WMP) player. Can be better HD playback for some old graphics cards. When the operating system is developed to Windows 7, the hardware environment of most users can already cope with the demand of high-definition playback. Therefore, the video acceleration function that plays a role in Windows XP is now somewhat outdated.

When Windows 7 users use WMP 12 to play HD video files, they often find that CPU usage is high and even 100% occupancy. This is probably because WMP 12 has enabled video acceleration. The video acceleration function has certain practical significance in the Windows XP era, but now it can smoothly run the Windows 7 hardware environment, which can basically meet the needs of high-definition playback. Therefore, we can shield it to save system resources.

Run WMP 12, click “Tools →Options", in the pop-up dialog box, switch to the "Performance" tab, cancel the default checkmark of the program, and enable the DirectX video of the WMV file. Acceleration & rdquo;, as shown below:

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

With the update and development of hardware, some functions that can be used in Windows XP system have been gradually lost in Windows 7 system. During the actual use of the user, the user can make trade-offs according to the actual situation to save system resources.
