Microsoft Windows has been a staple of modern computing, with each title in the series offering more innovative features. When it becomes time to retire one of their OSs, it can be troublesome for businesses. This coming January, two of the most utilized versions of the Windows OS--Windows 7 and Windows Server 2008 R2 will be losing support, effectively ending their viability. Businesses that still use these titles will have to come up with a plan about how they are going to proceed once Microsoft retires that software.
