where to download workspace 2010 from official site

According to https://support.microsoft.com/en-us/kb/2904784 , we need to use workspace 2010 to connect to SharePoint 2010. However, I cannot find an link from Microsoft to download workspace 2010. All the links returned from Bing looks to be third party and I am not sure if it is suitable to install downloads from these sites for Enterprise customers.
