Powershell Uninstall Script - Have a real headache

Question

I am currently writing a script that has involves a number of uninstalls of programs installed on a WES 7 device. One of the applications I need to uninstall (VMware Horizon View Client) asks for a restart. When this is part of the script, it seems to accept the default button (YES) and proceeds to reboot the device. The script therefore fails.

I would really appreciate your help in how to prevent this reboot from taking place.

FYI: This script is sent down via a management tool and is run in an elevated manner on the target.

This is my script:

set-executionpolicy unrestricted
#############################################################
# Un-install unwanted applications
#############################################################
$application = Get-WMIObject Win32_Product -filter "Name='ThinPrint Client Windows 8.6'"
$application.Uninstall()
$application = Get-WMIObject Win32_Product -filter "Name='2X Client'"
$application.Uninstall()
$application = Get-WMIObject Win32_Product -filter "Name='Adobe Reader X (10.1.4)'"
$application.Uninstall()
$application = Get-WMIObject Win32_Product -filter "Name='VMware Horizon View Client'"
$application.Uninstall()
$application = Get-WMIObject Win32_Product -filter "Name='VERDE VDI User Tools'"
$application.Uninstall()
$application = Get-WMIObject Win32_Product -filter "Name='vWorkspace Connector for Windows'"
$application.Uninstall()

#############################################################
# Remove Internet Explorer Access
#############################################################
dism /online /norestart /Disable-Feature /FeatureName:Internet-Explorer-Optional-x86

#############################################################
# Remove IE Browser LNK from Taskbar
#############################################################
del "C:\Users\User\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\Launch Internet Explorer Browser.lnk"

#############################################################
# Make Citrix Receiver the shell
#############################################################
Push-Location
CD 'HKCU:\Software\Microsoft\Windows NT\CurrentVersion\Winlogon'
New-Itemproperty -path .\ -name Shell -Type String -Value 'c:\program files\Citrix\Receiver\receiver.exe'
Pop-Location

set-executionpolicy restricted
# End of Script

I would very much appreciate some help in how to prevent the reboot half way through the script.

I strongly suggest NOT using Win32_Product. Every time Win32_Product is called it does a software consistency check of each installation. Not only does this make things very slow, it may also trigger a software repair if it finds something wrong.

Instead go into the registry and just call the uninstall string.

You can use msiexec's norestart flag to try to prevent reboots.
