将对象与 powershell 中的通配符字符串匹配

Question

Writing a script to get rid of certain Windows 10 bloatware and having some issues.

The intention is to check if the app exists before going ahead and removing it with Remove-AppXPackage. I added all the names to an array of strings with and with asterisks on both sides but I can't get a match while using -like or -match in my if statement.

I wrote the code below to try to make it work exactly as the following command:

Get-AppxPackage *windowsalarms* | Remove-AppxPackage

But instead, first check if that package exists. I'm assuming the original command is matching objects to eachother. And I'm realizing I'm trying to compare an object to string... So should I create an array of objects with just a name property for every single one and then try to compare them?

$AppsToRemove = @("*broker*"
                ,"3dbuilder"
                ,"windowsalarms"
                ,"officehub"
                ,"skypeapp"
                ,"getstarted"
                ,"zunemusic"
                ,"solitarecollection"
                ,"bingfinance"
                ,"zunevideo"
                ,"bingnews"
                ,"windowsphone"
                ,"bingsports"
                ,"xboxapp"
                ,"whiteboard"
                ,"sway"
                ,"todos"
                ,"lens"
                ,"soundrecorder"
                ,"onenote"
                ,"remotedesktop"
                ,"networkspeedtest")

Get-AppxPackage | ForEach-Object {

$Placeholder = $_.Name

    Foreach ($app in $AppsToRemove){

        If ($app -like $Placeholder) {
            Write-Host "Match"


        }else{
            Write-Host "No match"

        }

    }

}

Answer 1

Try something like this where you join your array into a [Regex] object. Then I got all the AppXPackages and piped that to a Where-Object to tell if they matched the original array. I added a -WhatIf at the end for testing. This can be removed when you want to actually run the script to remove them.

[Regex] $AppsToRemove = @(
    'broker'
    '3dbuilder'
    'windowsalarms'
    'officehub'
    'skypeapp'
    'getstarted'
    'zunemusic'
    'solitarecollection'
    'bingfinance'
    'zunevideo'
    'bingnews'
    'windowsphone'
    'bingsports'
    'xboxapp'
    'whiteboard'
    'sway'
    'todos'
    'lens'
    'soundrecorder'
    'onenote'
    'remotedesktop'
    'networkspeedtest'
) -join '|'

Get-AppxPackage | Where-Object -Property Name -Match -Value $AppsToRemove | Remove-AppxPackage -Verbose -WhatIf

I get the following output given that some of these are already removed on my machine:

What if: Performing the operation "Remove package" on target "Microsoft.AAD.BrokerPlugin_1000.16299.15.0_neutral_neutral_cw5n1h2txyewy".
What if: Performing the operation "Remove package" on target "Microsoft.WindowsAlarms_10.1804.1101.1000_x64__8wekyb3d8bbwe".
What if: Performing the operation "Remove package" on target "Microsoft.WindowsSoundRecorder_10.1804.911.1000_x64__8wekyb3d8bbwe".
What if: Performing the operation "Remove package" on target "Microsoft.ZuneVideo_10.18082.10311.0_x64__8wekyb3d8bbwe".
What if: Performing the operation "Remove package" on target "Microsoft.ZuneMusic_10.18091.10321.0_x64__8wekyb3d8bbwe".

The answer by @ShawnEsterman guided me to an idea that I'm more familiar with and I came up with the following that worked:

$i = 0
$AppsToRemove = @("broker"
                ,"3dbuilder"
                ,"windowsalarms"
                ,"officehub"
                ,"skypeapp"
                ,"getstarted"
                ,"zunemusic"
                ,"solitarecollection"
                ,"bingfinance"
                ,"zunevideo"
                ,"bingnews"
                ,"windowsphone"
                ,"bingsports"
                ,"xboxapp"
                ,"whiteboard"
                ,"sway"
                ,"todos"
                ,"lens"
                ,"soundrecorder"
                ,"onenote"
                ,"remotedesktop"
                ,"networkspeedtest")

$Packages = Get-AppxPackage | ForEach-Object {

Foreach ($App in $AppsToRemove){
    if($_ -match $App){

        Remove-AppxPackage $_
    }
}

}

Thanks Shawn for your guidance!
