How to Stop the Windows Vista Startup Black Screen (TMM)

Have you ever wondered why there was an empty black screen after Windows Vista finished loading? Then, after 10 to 15 seconds, your mouse cursor appeared and Vista starts up? This function is called the Transient Multimon Manager (TMM), which affects multimonitor capabilities in Vista. By following a few steps, you can turn off TMM and speed up your PC's system startup.


Instructions

1. Navigate to the "Start" menu and right-click on the "Computer" link on the right-hand side. Select "Manage" from the pop-up menu. After a few seconds, the Computer Management dialog will appear.
2. Navigate to the left side of the dialog and expand the "Task Scheduler" folder. Next, expand the "Task Scheduler Library," "Microsoft" and "Windows" folder.
3. Click on the "Mobile PC" folder. Right-click on the "TMM" listing and click "End." Right-click again and click "Disable." Doing this will stop TMM from starting, which will prevent the black screen from appearing at startup.

Tips & Warnings

To re-enable TMM, follow the steps but instead of clicking "Disable," click "Enable."

Only disable TMM if you don't run multiple monitors on your computer.
