Detect Windows 10 Version and update to latest build via powershell

Question

Hi

Im looking for a script if someone has made it that will check the windows build.
If it's less than 19042.572 then do the following:

Something Like

If

(Get-CimInstance Win32_OperatingSystem).BuildNumber < 19042 then

Set-ExecutionPolicy unrestricted

Install-Module PSWindowsUpdate

Import-Module PSWindowsUpdate

Get-WindowsUpdate -KBArticleID KBXXXXXX (This being the Latest Windows 20H2)

Install-WindowsUpdate -AcceptAll -AutoReboot

Hi，

The comparison operator in PowerShell is "-lt", not "<" and you should specify the if block using the curly braces.

if((Get-CimInstance Win32_OperatingSystem).BuildNumber -le 19042)  
{  
    Set-ExecutionPolicy unrestricted  
    Install-Module PSWindowsUpdate  
    Import-Module PSWindowsUpdate  
    Get-WindowsUpdate -KBArticleID KBXXXXXX -Install -AcceptAll -AutoReboot  
}  

Best Regards,
