Microsoft Windows XP has become the most widely used and installed desktop operating system, with over 60% of U.S. businesses running Windows XP as of 2013. Since introducing Windows XP in 2002, Microsoft has provided free software updates that add features and fix security problems exploited by viruses. However, Microsoft will not be providing updates indefinitely.
Instead, Microsoft will stop issuing security fixes to Windows XP, Internet Explorer 8 and Microsoft Security Essentials for Windows XP on April 8, 2014. It is possible and likely this deadline will be extended, and its also likely that Microsoft may issue security fixes for major problems that significantly affect large groups of Windows XP users. The best course of action is to begin upgrading or replacing Windows XP computers with Windows Vista, Windows 7, or Windows 8.
Windows XP 32-bit with service pack 3 (SP3) can be upgraded to Vista 32-bit SP1 and then the service pack 2 update for Vista must be installed. Only after upgrading to Vista SP2 can a computer be upgraded to Windows 7. Note that 32-bit versions of Windows XP cannot be upgraded to any subsequent 64-bit version of Windows. 64-bit versions of Windows Vista/7/8 provide support for computers with over 4gb RAM, while 32-bit versions of Windows are limited to recognizing only the first 3gb of RAM (4gb minus video memory usage).
There are no direct upgrades from Windows XP to Windows 7/8; instead, computers must first be upgraded from XP to Vista, and then from Vista to Win7 and then Win8. Performing an upgrade preserves all programs, data and settings, replacing only the operating system files with the newer version.
When changing to a 64-bit version of Windows Vista/7/8, there is no upgrade path available from 32-bit Windows. Instead, a new copy of Windows must be installed, requiring all applications to be re-installed. The previous version of Windows can be retained and the computer can be dual-booted to allow switching between versions of Windows on restart.
Along with the planned demise of Windows XP, new computers are no longer including hardware drivers for Windows XP, instead limiting their support to only Windows 7 and Windows 8.
