Windows 7 Will Not Update - Error 0x80070057 / Parameter Incorrect

I cannot get windows to update. I have used windows update agent fix it tool, but it always gets an error when trying to run it. I have tried turning off all firewalls and AV programs, but still cannot update. When going to services.msc, it shows update service as stopped. when I try to start it, I get the message:

'Windows could not start the windows update service on local computer. Error 0x80070057: the parameter is incorrect.'

When I click check updates under the windows update program, it says cant update due to service not running. I have checked my ipv6 and ipv4, and both are setup to automatic I have tried using tdsskiller to ensure no rootkits are present, and I'm clean. I ran AV scans and spyware scans, but all come up clean. I have ran system file checker, and chkdsk, but both were fine.
