Re-install Internet Explorer 6 or Outlook Express 6 in Windows XP

When you try to reinstall the same version of Internet Explorer, you may receive the following error message:

2. In the Open box, type regedit, and then click OK. 
3. Locate the appropriate registry subkey, right-click the IsInstalled (REG_DWORD) value, and then click Modify. 

To reinstall only the Internet Explorer 6 browser component on Windows XP, use the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{89820200-ECBD-11cf-8B85-00AA005B4383}
To reinstall only Outlook Express 6 on Windows XP, use the following registry key:

Remove the MsPMSPSv.exe service:
The WMDM PMSP service will be installed with Windows Media Player 7 on Windows 2000 and is necessary for MS Digital Rights Management. 
The service allows WMDM (Windows Media Device Manager) to copy audio content from a computer to a portable audio player. You can disable 
this service if you don't use Media Player. On Windows XP/2003 the WMDM PMSP service is an instance of svchost.exe called Portable Media 
Serial Number.

The most annoying thing about this service is that it is not uninstalled after you uninstall Windows Media Player 7? and just takes up s
pace and memory. There is a built-in way to uninstall it though. Just type "mspmspsv -u" from the command prompt (without quotation marks) 
and follow the on-screen instructions.

Disable RealPlayer realsched.exe 

When you install RealPlayer, it will add a process called realsched.exe to your startup configuration. realsched.exe periodically checks the Internet for updates. Even worse, even if you take it out of your startup configuration in the registry, simply running RealPlayer will make it return. While realsched.exe is relatively benign, I don't like processes running on my system without my permission. Here's how to disable it.

- Launch RealPlayer
- Click on the Tools and choose Preferences
- Under the Automatic Services category, choose Message Center
- Press the button marked "Configure Message Center"
- UNCHECK the option labeled Checking - Check for new messages
- Choose Yes when the warning pops-up
- Also, under Automatic Services, choose AutoUpdate and Uncheck Automatically download ...

If you haven't already, run Hijackthis or MSCONFIG to remove it from your startup configuration as well.

Disabling Speed Launcher in Acrobat 7.0 and Adobe Reader 7.0 

The Adobe Acrobat Speed Launcher is a program installed by Adobe Acrobat 7.0 and Adobe Reader 7.0 to optimize the speed of both programs.

The Speed Launcher is installed into your computer's Common Startup group and runs when your computer starts. The Speed Launcher quickly opens and closes all of the files that Acrobat or Adobe Reader will use when the application starts. Opening and closing the files allows your virus protection software to check these programs and add them to its list of safe files. The application opens more quickly because these checks have been performed.

To disable the Speed Launcher, remove the Speed Launcher icon from your Startup folder.

What Is the Osa.exe File and What Does It Do?

The Office Startup Assistant (Osa.exe or OSA) is a program that improves the performance of Office XP programs. Office Setup places a shortcut to the Osa.exe file in the Windows Startup folder; the file is named "Microsoft Office". 

The Osa.exe file does the following:
- Initializes automation.  
- Initializes some of the common fonts installed by Office XP.  
- Handles certain commands (New Office Document, Open Office Document, Help, and Screen Saver) on the Start menu and on the Office Shortcut Bar. 
- Displays Microsoft Outlook notifications when the Office Assistant is available. 

The Osa.exe file initializes the shared code that is used by the Office XP programs. When you use the Osa.exe file to initialize shared code, the Office XP programs start faster. If the Office programs, instead of Osa.exe, initialize the shared code, the programs take longer to start. 

Osa.exe can be safely removed from startup. 
The Office Shortcut Bar (OSB) may no longer start automatically, if you configured the OSB to start when Windows starts.

Command-line switches with OSA.exe:
-b This switch starts the Office Shortcut Bar when it is used with the "-l" switch.
-f This switch opens the Open Office Document dialog box at startup.  
-n This switch opens the New Office Document dialog box at startup.  
-s This switch starts the specified screen saver at startup. Note that if there is no screen saver selected under Display in Control Panel, you receive a message stating this.  
-o This switch starts the Office Shortcut Bar. 

Osa.exe starts the OSB if the following registry setting is present: 
Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Shortcut Bar
Name: AutoStart
Value: 1
Type: DWORD 
Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Osa\Autostart
Name: NotFindFast
Value: 1
Type: DWORD

The Windows User Mode Driver Framework service (Wdfmgr.exe) appears in Windows Task Manager after you install Windows Media Player 10

After you install Microsoft Windows Media Player 10, a new process appears in Windows Task Manager. This process is named the Windows User Mode Driver Framework service (Wdfmgr.exe). The Startup type setting for this process is Automatic.
Note The Windows User Mode Driver Framework service is a driver component that is used by Windows Media Player 10. The Windows User Mode Driver Framework service supports synchronization of content with hardware players. For example, an MP3 device is a hardware player.
If you do not have a hardware player, you can set the Windows User Mode Driver Framework service Startup type setting either to Disabled or to Manual. Later, if you obtain a hardware player and if you want to synchronize it with Windows Media Player 10, you can enable the Windows User Mode Driver Framework service by changing the Startup type setting back to Automatic.

This issue occurs because the Windows User Mode Driver Framework service is installed when you install Windows Media Player 10. By default, the Windows User Mode Driver Framework service Startup type setting is Automatic.

RESOLUTION
To resolve this issue, set the Windows User Mode Driver Framework service Startup type setting either to Disabled or to Manual. To do this, follow these steps: 
1. Click Start, click Run, type services.msc in the Open box, and then click OK.
2. In the list of services, right-click Windows User Mode Driver Framework, and then click Properties.
3. Click the General tab.
4. In the Startup type box, click Disabled or Manual, and then click OK.
5. On the File menu, click Exit.

The Machine Debug Manager, Mdm.exe, is a program that is installed with the 
Microsoft Script Editor to provide support for program debugging. The Microsoft 
Script Editor is included with Microsoft Office 2000.

The Machine Debug Manager runs as a service and is loaded when your computer 
starts. If you do not use your computer for debugging purposes, you can safely 
turn off the Machine Debug Manager.

How to Turn Off the Machine Debug Manager:

If you run Microsoft Internet Explorer 5 or later, you can turn off the Machine 
Debug Manager by turning off script debugging. To do this, follow these steps:

1. Open Internet Explorer. 
2. On the Tools menu, click Internet Options. 
3. Click the Advanced tab. 
4. Click to select the Disable script debugging check box, and then click OK. 
5. Close Internet Explorer. 
6. If you run Microsoft Windows 98 or Microsoft Windows Millennium Edition (Me), 
delete the registry value that starts the Machine Debug Manager. To do this, 
follow these steps.

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.

a.  Click Start, and then click Run. 
b.  In the Open box, type regedit, and then click OK. 
c.  In the Registry Editor, locate the following subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices 
d.  In the right pane, right-click MDM7, click Delete, and then click OK to 
confirm the deletion.

NOTE: The value for your version of the Machine Debug Manager may be different 
from MDM7. 
e.  Close the Registry Editor. 

NOTE: Running Detect and Repair in Office 2000 adds the registry entry for the 
Machine Debug Manager and causes it to run at startup. If this occurs on your 
system, use the previous procedure to remove the registry entry.
