I'm getting error 80070002 when trying to update my Windows 10 Ent to version 9860. Any clues on what might be the problem?
If you receive Windows Update error 80070002 while checking for updates, you need to remove the temporary update files that Windows uses to identify updates for your computer. To remove the temporary files, stop the Windows Update service, delete the temporary update files, restart the Windows Update service, and then try to check for Windows updates again.
I had a similar error, on updates to 9860 so i ask M$ WTH is wrong... OK seems that some DLs even via the official upgrade (check your ~BT Folder) sent the wrong Language. yep sure as hell did... so I burn to USB, via the esd2wim v4. then changed the \sources\lang.txt to read en-us then removed the en-gb folder and replaced with the en-us folder from my WinRT 8.1. closed the USB then inserted into and updated v9841 En-us with no issue. M$ is not 100% perfect... and I find asking MS what the ERROR indicates is the fastest method to get a answer.
If you can post the setupact.log and the setuperr.log files from~windows.bt\panther and it might be possible to resolve this. In general, 0x80070002 means File Not Found so we would have to look at the Windows Setup log file I mentioned in order to identify the problem.
