I use Incredimail as my e-mail program. My question is, is there a way to uninstall Outlook Express? I can’t find a uninstall program for it. I use XP home.
Outlook Express is an email program that comes preinstalled with Windows XP. Not everyone likes Outlook Express, however, and they may choose to use another email program, such as Incredimail. The steps below will help you remove Outlook Express completely from your computer. This will seem like a lot of steps to go through, but I promise to walk you through them all.
Click the Start button and then click Control Panel to open the Control Panel window.
Double-click the Add or Remove Programs icon in the first row. A list of programs installed on your computer will be listed.
Click Add/Remove Windows Components on the left side of the window.
The Windows Component Wizard dialog box opens. Find Outlook Express in the list, check the box next to it and then click the Next button.
Click the Finish button when the process is finished, and you will be taken back to the Control Panel window. Close this window.
The important files on your computer are automatically hidden to prevent you from editing them. For right now, we need to see these hidden files so we will unhide them.
Click Tools from the menu bar at the top and select Folder Options. Click the View tab and find Hidden files and folders in the Advanced Settings section. Click Show Hidden Files and Folders and then click OK.
Next, you need to rename the Outlook Express folders. To do this, click the Start button and then click My Computer.
Double-click Local Disk (C:)
Double-click the Program Files folder, the Common Files folder and the Microsoft Shared folder.
Right-click the Stationary folder and select Rename. Rename the file to old_ stationary.
Click the green Back button in the top left corner of the window three times. Double-click the Documents and Settings folder, your User folder and then the Application Data folder.
Right-click the Identities folder and select Rename. Rename the folder to old_identities.
Click the green Back button three times. Double-click the Program Files folder and then double-click the Outlook Express folder. Delete all of the files in this folder. Hold down the Ctrl key on your keyboard and click each file to highlight them. Right-click on any file and select Delete. Click Yes to confirm, and all of the files will delete. Make sure you do not delete the Outlook Express folder but only the files in the folder. Close the My Computer window.
Now, you need to delete the Outlook Express registry keys in the Windows Registry. Serious problems with your computer can occur if you modify the Windows registry incorrectly. You need to back up your registry before making any changes just in case something goes wrong. You can go here  for help with backing up your Windows Registry.
If you’re concerned about tinkering around in the registry, the following tip, Navigating the Registry  , helps explain navigation and should ease your mind.
Click Start, Run and type regedit in the Open box and click OK.
When the Windows Registry opens, you will notice there are folders with + signs next to them on the left side. This is where we will be working.
Deleting the registry key HKEY_LOCAL_MACHINES\Software\Microsoft\Outlook Express
Click the + sign next to HKEY_LOCAL_MACHINES to expand it. Click the + sign by Software to expand it.
Expand the Microsoft folder under Software and then right-click the Outlook Express folder and click Delete.
Do the same steps to remove the following Registry keys.
Close the Windows Registry.
The last thing we need to do is rename Outlook Express files. Search for the files below and rename them to filename.old. For example, Msoeacct.dll should be renamed to Msoeacct.old.
Click Start and then click Search. Click All Files and Folders on the left side.
Type Msoeacct.dll in the All or part of the file name field and click Search.
Right-click the file and rename to Msoeacct.old. If you receive a response from Windows about file protection click Cancel. Click Yes, if you receive a prompt that Windows does not recognize the file.
Do the same for the following files.
That was a lot of steps, I know, but if you followed them correctly Outlook Express should now be completely removed from your computer. Hope you enjoyed this tip!
