Registry informationImportant This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
- Click Start, type regedit in the Search programs and files box, and then press ENTER. If you are prompted for an administrator password, type the password. If you are prompted for confirmation, provide confirmation.
- Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows MultiPoint Server\
- On the Edit menu, point to New, and then click DWORD (32-bit) Value.
- Type MaxRedirectedVideoPlaybackSessions, and then press ENTER.
- Right-click MaxRedirectedVideoPlaybackSessions, and then click Modify.
- In the Value data box, enter the maximum number of sessions for which you want redirected video playback, and then click OK.
- Exit Registry Editor.
- Restart the computer.
- The value that you enter depends on the capabilities of your CPU, on your graphics subsystem, and on the video usage pattern of station users.
- You may have to test several values to determine the best choice for your system. We do not recommend that you set the value to support more than 12 sessions.
- If the registry key is not set when you apply the update rollup, it will use a default value of 12. Before the update rollup is installed, the value is unlimited and may exceed DirectX capabilities.
- If the registry key is set to 0, no stations will redirect video to the GPU.
Note This setting does not apply to websites that feature Flash video playback. For example, this setting does not apply to Youtube.
