Block-ADTAppExecution

SYNOPSIS​

Block the execution of an application(s).

SYNTAX​

Block-ADTAppExecution [-Processes] <ProcessDefinition[]> [[-WindowLocation] <DialogPosition>]
 [<CommonParameters>]

DESCRIPTION​

This function is called when you pass the -BlockExecution parameter to the Stop-RunningApplications function. It does the following:

  1. Makes a copy of this script in a temporary directory on the local machine.
  2. Checks for an existing scheduled task from previous failed installation attempt where apps were blocked and if found, calls the Unblock-ADTAppExecution function to restore the original IFEO registry keys. This is to prevent the function from overriding the backup of the original IFEO options.
  3. Creates a scheduled task to restore the IFEO registry key values in case the script is terminated uncleanly by calling Unblock-ADTAppExecution the local temporary copy of this module.
  4. Modifies the "Image File Execution Options" registry key for the specified process(s) to call Show-ADTInstallationPrompt with the appropriate messaging via this module.
  5. When the script is called with those parameters, it will display a custom message to the user to indicate that execution of the application has been blocked while the installation is in progress. The text of this message can be customized in the strings.psd1 file.
