Disabled DirectDraw video screenshots in Windows 7 are no longer black

In the Windows XP era, many users have been plagued by the "black pictures" after the video screenshots. In this regard, in the solution to the local playback when the screenshot becomes black, there are generally two ways to solve, one method is to use two different players, open the same file at the same time; another 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. This also means that Windows 7 users can't solve the blackening problem of the screenshot by "Disable DirectDraw".
By default, DirectDraw under Windows 7 cannot be disabled.
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 , then locate HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlGraphicsDriversDCI, then find and double-click "Timeout" in the right window, and then change the default value "7" to "“0”" in the pop-up window.
After the modification is completed, save the settings to exit, and then take effect the next time you start.
Method 2: Install Windwos 7 dedicated driver
Some Windows 7 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, failed to achieve the purpose of disabling DirectDraw.
This situation occurs because Windows 7 is different from Windows XP in terms of graphics card driver. Some video card users need to download and install dedicated drivers under Windows 7, some public version drivers, and some drivers under Windows XP. They cannot modify the state of DirectDraw under Windwos 7.
