I have a lenovo ultrabook with Win 8.1 installed, and I simply cannot install Update KB3035583. I've tried all kinds of things such as using sfc /scannnow, using the DISM tool cleanup and repair, etc. I keep getting error code 80070BC9. Sometime it tells me the update is not compatible as well. I really do not believe a system refresh should be necessary to fix this problem as some articles on the Internet suggest.
