I have two machines, desktop and laptop, both running Windows 7 Build 7600 (64-bit and 32-bit respectively) that just started getting the "Code 80070005" message when running Windows Update. I have seen many others with this issue (apparently it used to be an issue with Vista) but it's surfacing again on Windows 7. I have tried any of the proposed fixes: Rebuilding the "C:/Windows/SoftwareDistribution"Running the SubInACL tool to repair file and registry permissionsDisabling the firewall (Windows Firewall) and anti-virus (Avast Home) without any effect. Does anyone have a reliable fix yet? I'd rather not reformat both machines just because there's an incorrect setting somewhere.
