After I was installing a new SharePoint farm, I got this message while running the "Configuration Wizard" (step 5):
Failed to register SharePoint services
I tried to restart the system, stopp and start the services again, but nothing worked. In the end I had to delete some entries in the registry.
1. So, click on "Start", "run" and type in "regedit".
2. Now follow this path:
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Shared Tools/Web ServerExtensions/14.0/WSS/Services
3. There I started to delete every failed service that poped up.
