Hi I'm new

I noticed the system time in Windows 10 was wrong and that I was unable to communicate with time.windows.com
Does SDAntiBeacon-1.6 block this address? If so, which immunization option is responsible for it? There's a ton of Microsoft related entries in the host file but time.windows.com isn't one of them.

Also while I'm asking, does the computer need to reboot for the changes to take affect after immunization?
