Way back when Windows 7 was released, Microsoft began discussing the fact that they would one day pull the plug on Windows XP Support. Given the number of XP machines in use, Microsoft repeatedly delayed and postponed the final death knell for Windows XP. Well, it appears that XP is finally going out to pasture.
As of April 8, 2014, Microsoft will no longer provide service packs or security patches for Windows XP (and also Office 2003). What does this mean to you? If you have any Windows XP machines still running at your business, you should come up with a plan to replace or retire them. After support expires, these XP workstations will become a serious risk to your technology infrastructure because they will become significantly more vulnerable to viruses, spyware, and other malware.

Obviously, we are here to help with any of your XP migration plans. For most situations, we are recommending that our customers replace the Windows XP machines with Windows 7 or Windows 8 workstations. In some cases we can upgrade the existing hardware, but in most cases it will be much more cost effective to replace it with a new desktop workstation or a laptop. Contact us at email@example.com if you have any questions.
