Instant-Clone Clean-up

An instant-clone desktop pool is an automated desktop pool created from a golden image using the vmFork technology (called instant clone API) in vCenter Server.

Instant clone technology replaces View Composer linked clone as the process for creating non-persistent desktops in Horizon. In addition to using the instant clone API from vCenter Server, Horizon also creates several types of internal VMs (Internal Template, Replica VM, and Parent VM) to manage these clones in a more scalable way.

Sometimes it happens that when an Instant-Clone desktop and image is removed the internal VMs are not removed completely. From Horizon 7.11 and newer VMware introduced a tool called IcCleanup.cmd which is located in the C:\Program Files\VMware\VMware View\Server\tools\bin directory.
