After clean windows installation computer waw always connected to the internet. I installed all drivers using "Lenovo System Update" and than installed all updates from WIndows Update except KB2952664 as it was failing. Avira was installed after installing all KBs. Windows firewall was enabled as by default. I did not enabled Windows Defender manually after installation.
As for the second part I do not want to be first in line to be honest but I presume that without KB2952664 I will not be able to Upgrade to Windows 10 at all so I want to resolve this problem in advance.
