256986 Description of the Microsoft Windows Registry

SUMMARY

Microsoft Office installs, by default, the Microsoft Office 2000 File Optimizer. The purpose of the File Optimizer is to organize files that Office uses on your hard disk in a way that reduces the time required to start Office programs. The File Optimizer is designed to run automatically any time that it determines that your Office files are arranged in a less than optimal way.

When the File Optimizer runs, you have the option of canceling the optimization, as well as the option of preventing it from running again.

The "More Information" section of this article contains the steps you can take to prevent the Microsoft Office 2000 File Optimizer from running.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


If you want to prevent the Microsoft Office 2000 File Optimizer from ever starting, follow these steps.

NOTE: Turning off the Microsoft Office 2000 File Optimizer so that it never runs may significantly increase the startup times for the Office programs.

NOTE: The File Optimizer is installed only on computers that are running on Microsoft Windows 95 or Microsoft Windows 98. So there is no need to perform these steps if you are using Microsoft Windows NT.
  1. Click Start, and then click Run.
  2. In the Open box, type Regedit and then click OK.
  3. Search the registry for the following keys:

    HKEY_Local_Machine\Software\Microsoft\Office\9.0\Common
    HKEY_Current_User\Software\Microsoft\Office\9.0\Common

How to Disable Starting the File Optimizer on Windows Restart

If Office previously determined that the File Optimizer needed to run, you may have a value in the Windows registry to start the File Optimizer the next time that Windows starts. To manually turn off (disable) the running of the File Optimizer on Windows startup, follow these steps:
  1. Click Start, and then click Run.
  2. In the Open box, type Regedit and then click OK.
  3. Search the registry for the following keys:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
    HKEY_Current_User\Software\Microsoft\Windows\CurrentVersion\RunOnce

    Modify the key(s) according to the steps that follow.
  4. Look in the Name column of the right pane for OfficeTuneUp, and click to select it.
  5. With OfficeTuneUp selected, click Delete on the Edit menu, and then click Yes to confirm deleting the value.
  6. On the Registry menu, click Exit.
If you have turned off the File Optimizer from automatically running, you can always start it manually by double-clicking Otuneup.exe in the \Program Files\Microsoft Office\Office folder.
