But what does this have to do with the WSUS service, searching the web for a similar problem? The specific reason is also unknown http://www.david-obrien.net/2012/09/re-adding-pxe-support-to-configuration-manager-site/

Workaround: Rename or delete the program file in Safe Mode with command line, and then start the WSUS service.
