Uninstall custom features in a batch

By Anatoly Mironov

A funny powershell command I came upon today together with my colleague. Remove all your custom features (which start with something, say contoso):

Get-SPFeature 
       | Where { $\_.DisplayName.StartsWith("Contoso.") } 
       | ForEach { Uninstall-SPFeature $\_.Id -confirm:0 -force }

Have fun!
