0x80070715 for "swprv.dll", troubleshooting for creating system image for win 7 home premium

Do any of the suggestions you are attempting begin with the word "try"?

Tell us where you received these bogus suggestions - none of which make sense:

Further:

That makes no sense at all.

It seems that some folks are under the impression that any file with an extension of DLL needs to or can be registered and that is not true.

These suggestions are wild goose chases and you can tell that whomever suggestions did not verify their idea on their own system to see what happened (or what didn't happen).

For whatever it is the problem you are attempting to solve you need to find a source or solutions that work - not suggestions for things to try.

Ok, I can't make system image or back up of my win 7 home premium, shows errors below
