Windows Batch & Powershell: remove files based on multiple strings

Hello experts,

I am looking for a script that cover the following requirement:
Remove all files located in a folder which start with specific string.
The idea is to declare specific string multiple times in a variable.
Example
StringToRemove = “KO”; ‘OLD”; "ERR"
All the files which contain those string reported in StringToRemove should be removed.
Drill down mode required. In order to also remove all files located in subfolders.

Windows Batch & PowerShell & Vb Script are more than welcome.

If you have question, please contact me.

Thank you for your help.

In PowerShell like this, for example (in test mode, remove the -WhatIf to run it for real):

$stringToRemove = 'KO', 'OLD', 'ERR'

$includePattern  = $stringToRemove | ForEach-Object {"$($_)*"}
Get-Childitem -Path C:\Target -File -Recurse -Include $includePattern -WhatIf

Open in new window

Bill:
I tested your proposal but I got the following message displayed:

KO*.*

Open in new window

With a file that is named as following:
New Text Document - Copy_KO.txt
and file is not removed.
Thank you for your help.

@oBdA:

I tested your proposal but I got the following message:

Get-ChildItem : A parameter cannot be found that matches parameter name 'WhatIf'.

Open in new window

And I have the following file at folder:
New Text Document - Copy_KO.txt

I tested as following:

$CurrentDir = Split-Path $script:MyInvocation.MyCommand.Path
$Root = $CurrentDir + '\RefFolder'
$stringToRemove = 'KO', 'OLD', 'ERR'

$includePattern  = $stringToRemove | ForEach-Object {"$($_)*"}
Get-Childitem -Path $Root -File -Recurse -Include $includePattern -WhatIf

Open in new window

Thank you for your help.

@Bill: Thank you very much for your help. It works. Sorry for this change.
@OBdA: I was wondering how should I change {"$($_)*"} for contains.
The idea is to remove all files which contains $stringToRemove.
