The same Problem here - over 1 week no Update. Always get the Error code 0x80070490 on different Computers.
All the Tips (Store Fix / Update Fix) doesn't fix the Problem.
After SFC und DISM didn't Report an relevant Failure - I didn't want to reeinstall and excelent working System.
[Never touch a running System ;-) ]
So I take a look in the LOGS (Event Viewer or so) found Warnings in the Microsoft.VCLibs.
Most of the (Universal)Apps Need Visual C and I remeber: there was an Security Update related to Visual C.
I try to go back to the date of the Update (system recovery) but to long ago.
I Installed the MS Visual C++ 2015 Redistributable - restart my Surface - and got 16 Updates from the Store without Error Code.
So if you got Error code 0x80070490 -Install the Visual C++ 2015 Redistributable - I try this on 4 different Computers and it still works.
Good Luck
