Windows XP drops out of support on April 8. From that date it will no longer receive any fixes for security problems found in the operating system. Security researchers and hackers alike will, however, continue to find security flaws in the operating system beyond that date. It's likely that some unfixed flaws will become public almost immediately after April 8, as patches for other, supported versions of Windows—especially Windows Server 2003—will betray the existence of Windows XP bugs.
