Set up Ghost make a safe back up then let them play. Not allowing them admin rights in my opinion is treating them like kids,Anyone buying a pc will have admin rights.If you have a stable back up whats it matter???
My 9 year old daughter has admin rights on her pc.And touch wood she has never messed it up.I also allow her onto my network with net access unhindered.If she is installing something she can even tell what to click yes to and what not
And now she is a zinglebot in training
