The National Security Agency, responsible for protecting United States government communications and information systems, has released a informational datasheet advising Windows XP users to migrate to Windows Vista or Windows 7 as soon as possible.



From WinBeta:

Both Windows 7 and Vista provide substantial security enhancements over earlier Windows workstation operating systems such as XP. Many of these security features are enabled by default and help prevent many common attack vectors. In addition, implementing the 64-bit mode of the OS on a 64-bit hardware platform substantially increases the effort of an adversary to attain a system or root compromise. For any Windows-based OS, verify that Windows Update is configured to provide updates automatically.
