Allowing Windows updates in Windows firewall


New Member

I wanted to have my firewall block outbound connections. Now I succeeded in doing so, I cannot run Windows updates, without changing Windows' firewall from "block outbound connections" to "allow outbound connections".

Windows Update shows error 80240438. I allowed Windows Update in the firewall (its little name is wuauserv) and Windows installer (msiserver) and TrustedInstaller.

My goal is to have the Windows firewall block outbound connections while, at the same time, allowing Windows to update itself.

I found that by allowing some websites it might work, but don't know how

(don't know if it could help in my particular case)

Thanks to all trying to help,
