Okay, I have to ask. Why WOULD it replace a service?If it is a service that Windows default settings determine is on all the time...and the KEY has been deleted...the key will be re-created.Wahoo! Yahoo! Hallelujah! It worked!  I was able to successfully do a windows install repair!  All my users were still intact.  Everything I could have hoped.  After applying about 150 windows updates (seriously it had to be very close to that) I'm back in business.  My camera is now detected properly and shows up as a media device, launches the - "what do you want to do" wizard.

What is also VERY cool... I was concerned about loosing my linux Grub boot loader.  Windows didn't touch that!  I can still boot into Linux.  Well, I haven't actually tried it yet but the boot loader still displays and I have Windows boot by default.

Thank you to all who contributed ADVICE on this!
