Is the link below a legitimate Microsoft website?

https://www.catalog.update.microsoft.com/home.aspx

I have a very old Windows XP PC in storage that I would like to update to Service Pack 3 and I am wary of all the spoofed websites that my flood search results. So is the link to a legitimate Microsoft website?

Windows for home | Previous Windows versions | Windows update
