Why http microsoft connection in netstat check?


I checked established connections with "netstat" command in command prompt, and I found that there are some connections with ip’s of microsoft (I checked ip online) that have http (and not https) connection established, they bring to some svchost.exe in a Win32 folder of the system. I know that http connections are not safe, but I guess they are safe since they have microsoft ip, but why these connections are not encrypted (http)? Is it normal?
