I upgraded from Windows 8.1 to Windows 10. For the first three days, my windows update was working perfectly. However, I have not been able to install or check for any updates since 7/31. I am now getting an error message and I have tried retrying the update every day.
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)
The error code which you have provided is related to Windows defender.
Have you updated all drivers?
Let’s follow these steps which should fix the issue.
If you have any third party antivirus software and firewall disable them temporarily and make sure that the Windows Firewall is turned on. Then check if the issue reappears.
1. Press Windows + R and type in services.msc then press Enter.
2. In services window, locate Windows Defender service in the services list.
3. Verify that the Status is Started. If the Status column is blank,
right click on the service and select Start.
4 If you get error trying to force start the Windows Defender service, try to change the Startup Type to Automatic, and then restart the computer.
5. Next you can download an Windows updates and check the issue.
