Powershell script to run Windows updates.
The PSWindowsUpdate module will be used to check for and install updates.
The following script will install the module if required. If the module is already installed the version will be checked to make sure it is up to date. If needed the module will be upgraded.
# This module will install the PSWindowsUpdate Powershell module

To check for updates and install them silently:
Install-WindowsUpdate -MicrosoftUpdate -IgnoreUserInput -WhatIf -Verbose -AcceptAll
The above command will not reboot after update installation. To automatically reboot, add the -AutoReboot flag:
Install-WindowsUpdate -MicrosoftUpdate -IgnoreUserInput -WhatIf -Verbose -AcceptAll -AutoReboot
The above pair of scripts can be added to PDQ Deploy. A package can be created with step 1 being the powershell script to install module and step 2 being the command to install updates.
