I have had problems Activating and Updating Windows 7.
I have an Endian firewall appliance.
The main error I was getting was 0x80072EFD – unable to connect.
For me, the solution (after hours of heartache) was simple:
Go into Control Panel / Network and Internet / Internet Options / Connections tab / LAN Settings,
UNTICK “Automatically detect settings” and press OK.
Activation then works.
Updates then work perfectly.
Sorry – I’m not sure why this happens. I suspect it’s a bug in Endian version 2.2 which is fixed in later a version, probably relating to the internal Endian Proxy server which in my case is disabled anyway.
I hope this helps someone.
Many thanks to my son, Lachlan, who also had this problem, and figured out how to fix it after several days of heartache.
This works perfectly. Thanks. I understand previous versions of windows also had trouble updating under the same settings.
