I like Windows XP. It's a solid operating system, if a bit outdated. The Windows 7 Beta has been promising, and is a definite improvement in both speed and stability over Windows Vista. However, some people might not share my warm feelings towards Microsoft's latest OS, and would prefer that their new computers have XP preinstalled, or have the capability to install XP over Windows 7. It has been confirmed that users can do this without having to deal with Vista at all.
According to BetaNews, a Microsoft spokesperson came out and stated that users will be able to downgrade from Windows 7 to XP without a problem. This comes after the news that Microsoft would continue to support XP through at least June 2010. Users of Windows 7 may skip Vista entirely when downgrading.
XP is being kept on by Microsoft as the OS of choice for Ultra-Low-Cost-Portables (netbooks), though Windows 7 is fully capable of running on these sometimes underpowered machines. It is unclear if users who purchase netbooks with XP will be offered incentives to upgrade to Windows 7.
