Citrix Optimizer will remove required things for WVD machine, the simple example is “AppInstaller” which is needed for your MSIX packages. It will be default remove MS Paint, Sticky notes etc. It will disable Windows update by default.

Executing Citrix Optimizer via Command line

Citrix Optimizer comes with a PowerShell script which can be used to execute Citrix Optimizer via command line. This is so cool and I am already  using the command line execution as part of my Terraform and Azure DevOps pipelines. 🙂

You need to provide the source and Mode as mandatory parameters.

    .\CtxOptimizerEngine.ps1 -Source C:\Temp\WVD.xml -Mode Execute
