1.) Copy the whole module folder (after unzipping) to %WINDIR%\System32\WindowsPowerShell\v1.0\Modules
2.) Start up PowerShell ISE as admin from admin tools
3.) Set-ExecutionPolicy RemoteSigned
4.) Import-Module PSWindowsUpdate
5.) Get-WUInstall
6.) The rest should be automated with some prompts
After Reboot
follow the instructions to run the PowerShell script and it will force a Windows Update. Make sure you follow the instructions in the second relevant post:
This is a great solution! I just tested it and I only had one small issue. "Set-ExecutionPolicy RemoteSigned" was not sufficient in my case because the files were flagged as coming from another computer and were blocked when trying to import the module. Simple solution: copy the zip file locally and unblock the zip file BEFORE extracting the files, otherwise you have to unblock the files one by one. You can do that in the properties dialog of the file. You can also use "Set-ExecutionPolicy Unrestricted" but I do not suggest doing this.
If you want to execute without prompts, maybe to automate the process, you can execute:
Get-WUInstall -AcceptAll -IgnoreReboot
