Was having a problem with updates saying they were installed but coming back as uninstalled. Started trying a few steps and now Windows Update simply fails when I try to check for updates as follows:
Windows could not search for new updates
Code 80070490 Windows Update encountered an unknown error.
Steps I've taken so far...
1. Ran sfc /scannow which was having a problem with some corruption it couldn't fix
2. Ran SFCFix.exe and received 1161 unfixed SURT corruptions (log attached). It did seem to fix the problems with utc.app.json and telemetry.ASM-WindowsDefault.json.
3. Ran sfc /scannow again and it now comes up clean
4. Ran WindowsUpdateAgent-7.6-x64 with no effect
5. Ran Windows Update Diagnostic which also gives me an 0x80070490 error (screenshot attached)
6. Tried to install Update Windows Readiness Tool (Windows6.1-KB947821-v34-x64.msu) but it won't install. Just hangs at 80 percent after letting it sit for 3 hours.
7. Ran standard and aggressive fix instructions from here: https://support.microsoft.com/en-us/kb/971058
I made a copy of my CBS folder and zipped it but the file size limit for a zip is 7.15 MB and my zipped up folder is 71.5 MB.
Any help would be most appreciated. Thank you!
