Is web testing on Windows Server edition the same as Windows Desktop edition?

Yes. The license agreements of Windows Desktop editions (XP, 7, 8, 8.1, 10 Preview) do not allow us to provide remote access to our customers. Therefore, we use Windows Server editions with Desktop Experience, and use the versions of Internet Explorer made for Windows Desktop editions on those OSes.

Please refer to the following table to check which Windows Server edition maps to which Desktop edition.

Windows Server 2008 (on 32-bit machines)Windows 7 (for IE 8 and IE 9)

Since Windows Vista and Windows 7 are identical with respect to cross-browser testing, we support only Windows 7.
