I can probably get you one win rt 8.1.  I could really use one for win rt 8.0 though - I have one that is not upgraded that I need to restore.  email me at Jordan at Jordan mills dot com and we can figure out how to get the 8.1 recovery to you.
Hello,    I have an XPS 10 running windows rt 8.1. Its corrupted in a number of ways but here is the dilemna. I went to the Microsoft Store to see if they could reset the xps 10 to factory defaults. In order to do this, you need a recovery stick(usb). As it turns out this is not possible if you have already updated it to win 8.1. That function is not available. The Microsoft Tech said I needed to talk to Dell since their Surface RT usb recovery disk wouldn't work on the XPS 10.   What I need is a Dell XPS 10 recovery image so that I have the ability to "reset to factory defaults" No I don't have Dell support anymore on this but this seems to be a function that I should be able to keep even if not on support. Any suggestions are appreciated....  JGP
