If your computer uses the Windows XP operating system, pay close attention: Microsoft will be ending support for Windows XP on April 8, 2014. Many workers believe Windows XP works just fine, since 1 in 5 people still use the operating system. After all, the failure of the Windows Vista operating system, launched in 2006, with its security and incompatibility issues, reinforced the view of sticking with the tried and true XP. However, the upgrade to a supported operating system, such as Windows 7 or 8, is very necessary for maintaining the security of company computing environments.
