Microsoft App-V is a key component of The Microsoft Desktop Optimization Pack for Software Assurance which is an add-on subscription license available to Software Assurance customers. Microsoft App-V enables you to deploy software applications that are never installed to minimize regression testing, yet follow users anywhere on demand. It turns Windows applications into centrally managed virtual services that are delivered to any desktop or laptop client worldwide. It can also be integrated and managed within Microsoft System Center Configuration Manager 2007 and System Center 2012 Configuration Manager. For more information see the overview here.
