Windows 7 SP1 failed to install: Error 0x800f0826

Question

I received the  error (0x800f0826) when attempting to install SP1 both via Windows update today. It downloads fine and installs but fails and reverts back during the reboot.  This is Windows 7 Home Premium x32 .I've run the System Update
Readiness Tool with no effect. There are no hidden updates in Control Panel, the only Failed update is SP1.
Please help!!
