Uninstall Lexmark Printer altogether and then reinstall minus the fax. It
gives an option to exclude this module. If you can't remove it from
Add/Remove and the program has been uninstalled then download and use
Add/Remove Master, it allows the option to delete the entry anyway. http://www.freedownloadscenter.com/Utilities/File_Cleanup_Utilities/Add_Remove_Master.html
Start>Control Panel>Add or Remove Programs>lefthand side click add or
remove Windows Components. Second item should be Fax Services. Uncheck
it and click Next.
