I was trying to install the two latest WU updates on my Netbook running Windows 10 Build 10049. But I ran into error 0x80200059 and all of the available updates were throwing the same error including Windows Defender update. So I tried searching for the possible solutions and none worked except for one simple workaround that worked like charm. So, may be it helps other facing same issue.
It seems if your WiFi is set as “Metered connection” you can face this issue. So, you need to follow this path to resolve the error 0x80200059.
Settings–>Network & Internet–> WiFi—>Settings–>Switch off the “Set as Metered Network”.
