In this sample chapter from Exam Ref 70-688: Supporting Windows 8.1, you’ll learn how to support various operating system installations that are, for the most part, already in place, ranging from the most basic Windows 8.1 installations to native virtual hard disks to specialty Windows installations unique to a single enterprise. You’ll learn how to support desktop apps in many ways, too, including how to run those apps in virtual, cloud, or remote environments when running them on each workstation isn’t ideal. Finally, you’ll learn how network administrators can make their own apps available to users in a process called sideloading.
