Fix Window Defender Error 0x800705b4

Fix Window Defender Error 0x800705b4: Windows Defender is a built-in security tool inside Windows 10 which protects against malware & spyware. Windows Defender does its job to make your system secure from external threats and actively work as an Antivirus program. For this reason, many users don’t use 3rd party Antivirus application and they solely rely on Windows Defender, which seems fine as long as Windows Defender does its job. The best thing about it is that you don’t need to pay for it as it’s freeware tool from Microsoft and it comes pre-installed with Windows.

Now, what happens when you can’t start Windows Defender because of error code 0x800705b4 or 0x80508020. Well, if Windows Defender can’t start then your system will become vulnerable to malware & viruses, which is not a good thing if you ask me. You will receive the following error message while trying to run Windows Defender:

The service couldn’t be started.
This operation returned because the timeout period expired.
Error code: 0x800705b4

OR

Error code: 0x800705b4

An unexpected problem occurred. Install any available updates, and then try to start the program again. For information on installing updates, see Help and Support.
