Is ctldl.windowsupdate.com legit?

Is ctldl.windowsupdate.com legit? It seems malicious on VT. I have came across in the logs:

 

"svchost.exe has initiated a HTTP connection to http://ctldl.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab?blabla"

Check this:

An automatic updater of untrusted certificates is available for Windows Vista, Windows Server 2008, ...

It says for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. But where I saw is Windows 10. So, can we say still legit?
