Cant update- Cumulative update preview for windows 10 version 20H2 for x64 - based systems (KB5004296) Any solution?
mine has the same issue any ideas yet?
I had the same issue. I had no "PortableOperatingSystem" in my registry and I solved it by adding the "PortableOperatingSystem" file manually. You can give it a try if you have the same problem.
