Under Windows XP systems, many users have turned on the video acceleration function of Windowsx Media Player (hereinafter referred to as WMP). In this way, some old graphics cards can achieve better high-definition playback effects. When the operating system developed to Windows 7, the hardware environment of the vast majority of users could already cope with the needs of high-definition playback. Therefore, the video acceleration function that played a role in Windows XP is now somewhat outdated.
When Windows 7 users use WMP 12 to play high-definition video files, they often find that the CPU usage remains high, or even 100%. This is probably because WMP 12 turns on the video acceleration function. The video acceleration function had a certain practical significance in the Windows XP era, but now the hardware environment that can run Windows 7 smoothly can basically meet the needs of high-definition playback. Therefore, we can block 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 program's default check "Enable DirectX video acceleration for WMV files", as shown below:

After modification, save the settings and exit.
Editor's comments:
With the update and development of hardware, some functions that used to be functional in Windows XP systems have gradually lost their functionality under Windows 7 systems. During actual use, users can make choices based on actual conditions to save system resources.
