If you are among those who still use windows XP or Vista (or even Windows 2000) and you had no chance (hard to believe though) to test Windows 7 Beta or Windows 7 RC (the latter was offered to those who wanted to test it for free, for almost a year - until March 1.), Microsoft has prepared a surprise (in the good sense of the word) of all beauty: a demo site - Windows 7 Professional – which allows you to perform a test drive of the most important features of this operating system.
To be able to perform a test drive of the operating system Windows 7 Professional you must make sure that your PC meets the system requirements, that you have JavaScript enabled and that you have ActiveX Control installed.
Windows 7 Professional Test Drive.
Note: to be able to try for free (and without installation) Windows 7 Professional you must use Internet Explorer 6, 7 or 8. Drive safely! ;)
