How to set up shared directory in win7

        What can I do if DirectDraw cannot be disabled in Windows 7? In the Windows XP era, many users have been troubled by the "black picture" after the video screenshot. 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. Windows XP and Windows 7 users should be aware (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 problem of blacking out 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_MACHINE\\SYSTEM\\CurrentControlSet\\Control \\GraphicsDrivers\\DCI, then find and double-click "Timeout" in the right window, then change the default value "7" to "0" in the pop-up window. After the modification is complete, save the settings to exit, then It will take effect when it is started. Method 2: Installing the Windwos7 dedicated driver may have some Windows 7 users will find that after modifying the registry and restarting the computer, DirectDraw is still enabled under Windows 7, that is, by modifying the registry method, the purpose of disabling DirectDraw is not achieved. . This situation occurs because Windows7 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 Windows XP drivers. They cannot be used under Windwos7. Modify the state of DirectDraw.
