Yes there is, they are different operating systems. VIsta was very unstable, and was replaced by Windows 7 less than two years later.

In windows vista you can only turn UAC on or off. In windows seven you can choose when you want it to appear like just after installing a program or changing a windows setting. You can also choose if it should dim the display or not.
No. Due to the length of time between the releases of Windows XP and Windows Vista, as well as Windows Vista ditching support for some legacy technologies, there are many devices that will not function in Windows Vista but work in Windows XP.
There are three versions of Windows Movie Maker:Windows Movie Maker v2.1 (for Windows XP)Windows Movie Maker v2.6 (for Vista/7)Windows Live Movie Maker (Vista/7 Support only)The only differences between versions are add-on features and OS dependency.
No your windows 7 will not deleted
From what I can gather, Windows 7 improves on the security holes that were left in Vista as well as adding new graphics etc
That edition of Windows Vista does not exist. Windows Vista exists in two editions for home users: Windows Vista Home Basic and Windows Vista Home Premium.
The difference between windows XP and Vista are: The Box colors, instead of being solid colors, they're translucent. The Text on the boxes differ as well. You can also download widgets on the Vista. However, the XP is faster. vista is also trying to look/work like an i-mac with many small extras compared to xp although does not really work as is sort of half way between an imac and an xp
No.
THere is no such OS called windows premium., but in vista there are many flavours called vista basic, home premium and vista ultimate. In these variations the higher you go the more extra features u get and obviously the more you pay for it. LIke vista basic does have windows aero and home premium does not have dream scenes, bit locker etc which ultimate has., but the basic OS is the same. :)
XP, if you can scratch Vista and go for Windows 7
