What can I do if DirectDraw cannot be disabled in Win7 system

DirectDraw is the basic part of DirectX for video input and output. DirectDraw makes it easy to program efficient video processing programs. As long as the user's hardware supports DirectDraw, you can ensure that your code can handle them. So if DirectDraw in Windows7 can't be disabled, how can I solve it?
In the xp era, many users have been troubled by the "black image" after the video screenshot, which is happening when solving local playback. The screenshot becomes black. There are generally two ways to solve it. One method is to use two different players to open the same file at the same time; the other method is to disable DirectDraw. Users familiar with Windows XP and Windows 7 should know (by default) that DirectDraw is enabled under Windows XP and Windows 7. The difference is that under Windows XP users can disable it, and under Windows 7, it can't be disabled, which means that Windows 7 users can't solve the blackening problem of the screenshot by "disabling DirectDraw". By default, DirectDraw in Windows 7 cannot be disabled, but we can disable it by other workarounds:
Method 1: Modify the registry
Under Windows 7, run the Registry Editor, and then navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlGraphicsDriversDCI Then find and double-click "Timeout" in the right window, then, in the pop-up window, change the default value "7" to "0".
After the modification is completed, save the settings to exit, and then next time It will take effect at startup.
Method 2: Install Windwos7 dedicated driver
Some Windows7 users may find that after modifying the registry and restarting the computer, DirectDraw is still enabled under Windows 7, that is, by modifying the registry method, Can achieve the purpose of disabling DirectDraw.
This situation occurs because Windows7 is different from Windows XP in terms of graphics card driver. Some graphics card users need to download and install dedicated drivers under win7, some public version drivers, and some Windows XP drivers, they are Windwos7. The following is the state of DirectDraw cannot be modified.
As with other DirectX components, DirectDraw maximizes the use of hardware to perform a specific function whenever possible, and allows features that are not supported by the hardware to be implemented in software emulation.
