Windows 7 was launched worldwide on Oct 22. Its the replacement for vista which unfortunately is a failed product since XP. Vista's heavy memory usage plus security orientated settings though good, failed to win the hearts of many XP users including business like my company.Despite deployed successfully Vista business on some workstations and desktop in production environment, our testing conclude that Vista business even when locked down, does not provide the stability nor performance of XP Pro. so when Windows 7 Professional (not the RTM version) is available for us 2 months before the Oct 22 launch to test, we decided to test it out.
To my surprise, it's 1) fast to install when compare to Vista business and provided most of the device drivers, more than XP Pro. We tried both a upgrade from Vista to Windows 7 & a fresh installation of Windows 7. both result are the same: good! 2) its memory demands is low, we test on a Core duo machine running on 512MB ram and it performs like XP Pro, stable and fast.
Its interface needs to get use to; users of vista OS should not have any problem with Windows 7. We also tested our existing applications like Sophos AV, SAP, engineering software like UG NX4 etc on windows 7 and do not encounter any issues despite that these applications are designed more for XP Pro.
I like the User Access control (UAC) which was a nightmare in Vista OS. Windows 7's UAC is less noisy and provides the necessary protection we are looking for.
On the whole, I think Microsoft do address the shortcoming of the vista OS with the windows 7 OS. Looks like I have to work out the migration plan to change some if not machines to Windows 7.
