Remove windows apps

Below is our worklet to uninstall a Windows app - keep in mind, you need to enter the name/syntax of the app exactly as it appears in the “Apps and Features” folder (this is mentioned in the worklet). 

EVALUATION CODE

<#
.SYNOPSIS
    Uninstall Application by Name - Evaluation Script
    OS Support: Windows 7 and above
    Required modules: NONE
.DESCRIPTION
    This worklet is designed to grant an Admin the ability to uninstall an application with minimal knowledge of the bitness,
    installer type, or uninstall command line. By placing an application name between the single quotes, the worklet will
    scan the registry for the matching application. If the application is found, it will exit with an Exit code of '1' and
    flag the device for remediation.

    Usage:
    $appName: The application name provided must match exactly as it is displayed in "Programs and Features" (Add or
    Remove Programs) for Win7/8.1, and "Apps and Features" for Win10. Universal Windows Platform (UWP) applications are
    not currently supported in this worklet.

    Additional Notes:
    Some software (such as M365 Apps) installs as a "suite" even though each component could have its own registry entry.
    This type of installation is not supported with this worklet. For more information please see the software vendor's
    support documentation.
.EXAMPLE
    $appName = '7-Zip 19.00 (x64)'
.EXAMPLE
    $appName = 'Microsoft Silverlight'

REMEDIATION CODE

<#
.SYNOPSIS
    Uninstall Application by Name - Remediation Script
    OS Support: Windows 7 and above
    Required modules: NONE
.DESCRIPTION
    This worklet is designed to grant an Admin the ability to uninstall an application with minimal knowledge of the bitness,
    installer type, or uninstall command line. By placing an application name between the single quotes, the worklet will
    scan the registry for the matching application, and perform an uninstall based on the applications "UninstallString".

    Usage:
    $appName: The application name provided must match exactly as it is displayed in "Programs and Features" (Add or
    Remove Programs) for Win7/8.1, and "Apps and Features" for Win10. Universal Windows Platform (UWP) applications are
    not currently supported in this worklet.

    $exeCmd: You should modify this line if the application was installed via an EXE Installer and has specifc parameters
    to suppress restarts or perform a silent removal. Please see the software vendor's support documentation for specific
    instructions. (NOTE: $exeCmd is only applied to EXE Installer removals.)

    Additional Notes:
    Some software (such as M365 Apps) installs as a "suite" even though each component could have its own registry entry.
    This type of installation is not supported with this worklet. For more information please see the software vendor's
    support documentation.
.EXAMPLE
    $appName = '7-Zip 19.00 (x64)'
    $exeCmd = '/S'
