Error Code 80070005

[Jason Custer]

I got that error code repeatedly while trying to install an update for
Windows Defender just now. Anyone know what it is, why it's happening, and
how to fix it and get the update to work?

Could possibly be just a time out session connecting to the Windows Update
server or your Windows Firewall is blocking it from connecting.

Do you have the latest update client for your system?
