Hi, I have a machine with Windows 8.1 Pro WMC legit installed. I have installed GWX control panel (don't want W10 now). Think I have run DWS. once. The issue: Frequently , Windows 8.1 show not activated, and got I the watermark if I am disconnected from Internet. I Found an error into system log: unable to connect "IP 184.108.40.206" ... Witch is : ECN-NETWORK a-0001.a-msedge.net. Does Windows 8.1 needs to be connected to MS servers in order to run ? What's wrong with activation status. ?
