Hi Jennifer. I'm Greg, a volunteer installation specialist and 8 year Windows MVP, here to help you.
After uninstalling the Upgrade Assistant and deleting it's folder from C, I would also immediately run the Hide Updates Tool to catch and hide the Version Upgrade before it starts installing again: http://download.microsoft.com/download/f/2/2/f2...
If you cannot do this then the only way to block the Upgrade from reappearing is to set your connection as metered to stop Windows Updates:
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved. http://www.windowscentral.com/how-set-ethernet-...
