windows update error

[Jackske 0]

Hi,

When I try to run Windows update I got a message "error 0x800706d9".

My searches on​ Google tells me that the problem is that Windows firewall is turned off.

Of course, it is turned off because Eset manages the firewall.

I did try to deactivate Eset firewall but I never succeed to activate Windows firewall.

I don't understand why Microsoft wants their firewall to be turned on, to install updates?

Thanks for any help,

Jackske
