How do I clear WePO out of Windows?

WēPO is an add-in, ActiveX module for web pages. These are stored within the Windows directory in different locations (depending on your release of Windows and whether the user has administrative permissions).

The first place to look is in the Internet Options (under the browser's Tools menu item or in the Control Panel). Under the Programs tab, you can click on "Manage add-ons" and from here disable it and update it.

Likewise, you can un-register the product and then update it through the web site in question. Check the WēPO documentation for more information.
