Many clients have asked us whether it is worth upgrading to Windows 7 from XP or Vista. We are very impressed with Windows 7. It has run all our software applications without a hitch. Some errant older applications have been reported to have some compatibility issues with Windows 7. For that reason Microsoft has provided free of charge a solution called XP Mode. It is available from the Microsoft web site for users of Windows 7 Professional or higher. XP mode can be found at the following URL, http://www.microsoft.com/virtualpc.
