No Windows XP and Windows Vista?
Microsoft appears to be drawing a clear “line in the sand” with regard to platform support and Internet Explorer. As I mentioned at the outset of this article, Internet Explorer 10 supports only one Microsoft desktop operating system: Windows 7.
I foresee this decision creating more than one wrinkle among organizations that have developed line-of-business (LOB) applications for both Internet Explorer and their XP desktops. What if their LOB apps do not run properly on IE9 or IE10what then? The migration of a client computer fleet from XP to Windows 7 is not a trivial undertaking.
Regardless, so long as you have a 32- or 64-bit edition of Windows 7, you can install, run, and uninstall IE10 with a minimum of muss, fuss, or greasy aftertaste.
