Hi,

We have few PCs where start-wuscan PowerShell cmdlet is not available to run. These PCs run 1909, 20H1, 20H2 builds. Wondering how is this cmdlet got broken or missing, and second how to restore it back ?

PS C:\WINDOWS\system32> start-wuscan

    The module is removed in version 2004 (20H1), and thus 20H2 too

    you either have to rely on the manual commands to run the scan
    e.g.

    $Session = new-object -com "Microsoft.Update.Session"
    $ctr = "(IsInstalled=0 and DeploymentAction=*) or (IsInstalled=1 and DeploymentAction=*) or (IsHidden=1 and DeploymentAction=*)"
    $Result = $Session.CreateupdateSearcher().Search($ctr).Updates
    $Result | Select Title,Identity,IsHidden,LastDeploymentChangeTime,KBArticleIDs | Format-List -Property Title,@{l='UpdateID';e={$_.Identity.UpdateID}},@{l='PublishedDate';e={$_.LastDeploymentChangeTime.ToString('yyyy-MM-dd')}},@{l='KBArticle';e={$_.KBArticleIDs}},IsHidden
    

    or install external module PSWindowsUpdate

    Install-PackageProvider -Name NuGet -Force
    Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
    Install-Module -Name PSWindowsUpdate

    Check your $env:PSModulePath and verify that it contains C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules

    Verify that this file exists: C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules\WindowsUpdateProvider\WindowsUpdateProvider.psd1

    (get-module -ListAvailable windowsupdateprov*).path

    Hi,

    Check if the module WindowsUpdateProvider and the file C:\Windows\System32\WindowsPowerShell\v1.0\Modules\WindowsUpdateProvider\WindowsUpdateProvider.psd1 exist. If yes, please help to post the contents of the psd1 file.

    Best Regards,
