Windows Compatibility Center
A few weeks I received by Twitter tip this Compatibility Center but definitely not yet used.
The Arnaldo Fagnani posted about this and I noticed how this information is relevant (http://www.arnaldofagnani.com.br/blogs/post/compatibilidade-windows-7.aspx).
The Compatibility Center is not limited to software but also brings if the version is compatible with 64 bits, which facilitates much at the time of purchase of new hardware or software evaluation. Remembering that hardware and software compatible with Windows 7 is also compatible with Windows Server 2008 R2.
