uninstalling m.e.

IF when you installed ME, you chose to keep your WinSE system. The process can be reversed.
IF you kept the old files Add/Remove will uninstall ME.
If not, your faced with reformatting and reinstalling WinSE and all the applications.
Of course, be sure to back up any imprtant files first.

As DKlippert stated, you can't just un-install the OS.

I myself agree with the complete reformat of the hard drive as the best approach.

However, there is another way. You will still need to re-install all of your application programs. But you will keep your files and settings intact.

First back up any important files and settings.
When I do this, I save things like favorites in a seperate folder.

Boot from a startup floppy.
Delete the files in the root directory of the boot ("C") drive.
Switch to the Windows folder, and use the delete tree command to remove the windows folder and all subfolders.
You now have a system without Windows Me.

Now you can re-install 98SE.

Remember to do a hardware inventory, and download the latest drivers for everything.
You will also need to install a newer version of IE, and of course, all of your applications.

Why do you want to go back to 98SE?
If it is for stability, I would consider switching to XP Pro instead. The more I use it, the more I like it.
