Using Window 8.1, today I get updates and than it say update not complete undoing changes....... but it stuck here. I does system restore but I get error on this
Which is unspecified error accured during system restore (0*80070017). And I don`t have sysm image to do system image recovery.. please help me it ruined my whole day..

I see this happen to folks that use some registry cleaners .
These cleaners destroy restore points and other things.
Sorry you have no back up , I hope in the future you will .
I'm thinking now you should contact the maker of the computer to see if you can purchase the restore media.
