Delete extra Windows XP installations

During the process of installing Parallels I ended up with 5 installations of Windows XP (please don't ask how that happened ...), so now I would like to delete 4 of them. Can someone tell me how to delete them. Thanks.

 

When you start parallels, you have to choose witch vm you want. Choose one that you want to delete. Do not start vm but click on "File" in taskbar and there you will find "Delete"

Repeat untill every vm is deleted.

 

Thank you so much. It worked like a charm.
