Can anybody tell me whether the Inspiron 560 desktop comes with proper Windows 7 disks (I believe Dell refer to these as "reinstallation" disks) or just "restore" disks?  I'm considering buying an Inspiron 560 but the ability to do a complete format and clean reinstall of Windows (like this) after purchasing is quite important to me.  I don't just want to be able to "restore" the system complete with preinstalled junk.  I will be buying from Dell's UK store, if that makes any difference.

I've tried Dell's customer support line, but they appeared to be unable to give me a straight answer, which got me a bit worried: "Does the Inspiron 560 come with proper WIndows disks?" "The disk offered is a restore disk." "Can I do a manual reinstallation of Windows with that?"  "You can do that with a reinstallation disk."  "Does the Inspiron 560 come with a reinstallation disk?" "It comes with a restore disk." etc...
