Microsoft is scheduled to release its latest Windows Operating System, Windows 7, on October 22, 2009. Windows 7 has received some good review from beta testers and is expected to bring in some big revenue for the software behemoth. Windows Vista had a huge launch, but it left many users unhappy with its features and unnecessary bloatedness. So far Windows 7 seems to have left a positive impact on its many beta testers.
If you are currently using Windows XP (home edition or pro edition) then you would have to do a custom install to upgrade to Windows 7 i.e. basically do a complete install of the new OS. The same holds true for many Windows Vista versions. Take a look at the following Windows 7 upgrade chart created by Walt Mossberg of Mossblog and see what you may have to do to install windows 7 depending upon your current windows OS.
Lets hope that a custom install (a full complete install) of Windows 7 proves to be worth the effort for XP and Vista users.
