Windows 7: Windows Update KB2310138 Error Code 80070666

Windows Update KB2310138 Error Code 80070666

Windows Update flags an optional update: Definition Update for Microsoft Security Essentials - KB2310138 (Definition 1.129.991.0) but when I try to install it, I get Error Code 80070666.

I've done the full Install the latest Microsoft Security Essentials definition updates thing (downloaded mpam-fe.exe and nis_full.exe then run both as Administrator). WU still says I need KB2310138.

If I try to update in MSE, I get "Security Essentials couldn't complete .... because of an Internet or network connectivity problem." well I'm online now aren't I?

Any thoughts?

Hello Nigel,

You might see if using OPTION TWO in the tutorial below may be able to allow Windows Update to work properly afterwards.

Windows Update - Reset

Hope this helps,
Shawn

Hi Shawn,

Thanks for trying, but nothing has changed, after a reboot.

OK, fixed it.
  • Uninstalled Microsoft Security Essentials
  • Reboot
  • Re-installed Microsoft Security Essentials
  • Update, all OK
Odd, because I thought it was a Windows Update problem as well.

Had the same problem, since a failed important update of MSE client to 4.5.216 (which incidentally no longer appears).

Had already tried a reinstall; OPTION TWO eventually worked for me, after several days of trying MS Fixits, SURT, etc.

Thanks Shawn.
