How can you check that each VM has the new version of the application?

Your role of Systems Administrator at ABC.com includes the management of the company’s
private cloud. The company has a System Center 2012 infrastructure that includes the following
servers:
ABC-SRV1 runs System Center 2012 – Configuration Manager (SCCM).
ABC-SRV2 runs System Center 2012 – Service Manager (SCSM).
ABC-SRV3 runs System Center 2012 – Operations Manager (SCOM).
ABC-SRV4 runs System Center 2012 – Virtual Machine Manager (SCVMM).
The private cloud hosts a virtual desktop infrastructure (VDI) that consists of 100 virtual machines
(VMs) running Windows 7 Enterprise.
A corporate custom application is deployed to each Windows 7 VM. The vendor of the application
releases an important security update for the application.
You need to ensure that all Windows 7 VMs have the new version of the application installed.
