Solve the problem that Win 2008 and Vista cannot accelerate the video card

Solving the problem that the graphics card cannot be fully accelerated under Windows Server 2008 and Vista system

Ignore a problem when installing the Windows Server 2008 system. I have not installed the video card driver after installing the system. At the time, the "personalization"---“display settings ---<quo;troubleshoot"---<;hardware acceleration" can be fully accelerated, but this acceleration is not much The effect is that when the graphics card driver is installed and the computer is not restarted, the graphics driver is not fully effective, so the hardware acceleration can still be fully opened.

After rebooting, I found that the "Hardware Acceleration" option turned gray and could not be set. At this time, the hardware acceleration actually only turned on about 20%. When we watched HD movies or 3D games, Will find obvious unclear.

There are a lot of people who propose to use the XP version of the driver instead of the imperfect driver under Vista. This method can make the hardware acceleration fully open, but at the cost, we lose the Aero effect unique to Vista. Occasionally, I saw a full acceleration patch on the Internet. There are three dll files related to the display, which are used to replace the three corresponding files in the C/disk/windows32 folder (see the following network disk download). Address), you can achieve the function of turning on the adjustment hardware acceleration option.

But another problem we encountered was that the system files were strongly protected. The normal permission settings were unable to complete the replacement function. We can create a new registry file as follows:

Note: If you have installed Vista Optimizer (click here to download the latest version), please skip the registry, the right-click management in Vista Optimizer has this option to add administrator privileges.

//////////////Save the following contents of this line as a .reg file ///////////////////

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\\*\\shell\ unas] @="Administrator Ownership" "NoWorkingDirectory"=""

[HKEY_CLASSES_ROOT\\*\\shell\ unas\\command] @="cmd.exe /c takeown /f \\"%1\\" && icacls \\"%1\\" /grant administrators :F" "IsolatedCommand"="cmd.exe /c takeown /f \\"%1\\" && icacls \\"%1\\" /grant administrators:F"

[HKEY_CLASSES_ROOT\\exefile\\shell\ unas2] @="Administrator Takes Ownership" "NoWorkingDirectory"=""

[HKEY_CLASSES_ROOT\\exefile\\shell\ unas2\\command] @=" Cmd.exe /c takeown /f \\"%1\\" && icacls \\"%1\\" /grant administrators:F" "IsolatedCommand"="cmd.exe /c takeown /f \\"%1\\" && i Cacls \\"%1\\" /grant administrators:F"

[HKEY_CLASSES_ROOT\\Directory\\shell\ unas] @="Administrator Ownership" "NoWorkingDirectory"="" Br>

[HKEY_CLASSES_ROOT\\Directory\\shell\ unas\\command] @="cmd.exe /c takeown /f \\"%1\\" /r /dy && icacls \\"%1 \\" /grant administrators:F /t" "IsolatedCommand"="cmd.exe /c takeown /f \\"%1\\" /r /dy && icacls \\"%1\\" ; /grant administrators:F /t"

//////////////Save the contents of this line as a .reg file ////////////////////

Everyone saves the above as a reg file, then double-clicks the .reg file to add it to the registry.

So in the right-click menu, we have an option to "ownership ownership", find the corresponding three files in the C drive windows/system32 folder, right click "admin" Get ownership” then copy and replace the new file.
