I had this issue with Windows Update, it would download the updates and they would fail. The Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3213986) was trying everyday and failing. After much searching for a fix I finally found the following and Step 1 with Step 2 fixed my problem! Yay!!
Windows update now works and the KB3213986 along with various others has finally installed.
The error message is:
There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x800705b4) or (0x80072af9) or something similar in ( )
Try the below methods and check:
Method 1: Run the SFC.
Follow the below steps:
- Open Command Prompt.
- Select “Run as Administrator”.
- Type “sfc /scannow” without quotes and hit Enter.
Now check for the issue.
Method 2: Run the DISM Tool.
If the issue persists, I would have you run the DISM tool to check the system health and will try to restore the files.
- Click on 'Start'.
- Enter 'Command prompt' in the Search box.
- In the list of results, swipe down on or right-click Command prompt, and then tap or click 'Run as administrator'.
- In the Administrator: Command Prompt window, type the following commands. Press the Enter key after each command:
DISM.exe /Online /Cleanup-image /Scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth
To close the Administrator: Command Prompt window, type Exit, and then press Enter.
Note: The tool might take 15-20 minutes to finish running, so please do not cancel it. Reboot and retry the Updates, it worked for me.
If the issue still remains, try manually reset the Windows Updates Components once again and then reinitiate the Windows Update process.
