Filter and delete registry values ​​using Where-Object

Question

I'm not sure why I find it so difficult. From under a specific registry key, I would like to request specific registry values ​​based on their data (rather than name) and delete the resulting registry values.

For instance:

How to remove any values ​​in this key that contain, say, "foo". I can list the registry values ​​with Get-ItemProperty 'HKCU:\Software\Policies\Google\Chrome\RestoreOnStartupURLs', but it mixes some junk along with the actual data:

1            : http://foo.example.com
2            : http://bar.example.com
PSPath       : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\Software\Policies\Google\Chrome\RestoreOnStartupURLs
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\Software\Policies\Google\Chrome
PSChildName  : RestoreOnStartupURLs
PSDrive      : HKCU
PSProvider   : Microsoft.PowerShell.Core\Registry

I tried to connect to Where-Objectbut cannot find a query that works. And then I need a cmdlet Remove-that can handle the result. Does anyone have any ideas?
