My son got a netbook for christmas (acer aspire one with windows 7 starter), so i thought i'd be clever and set myself up as an administrator and him as a standard user.
Anyway wahtever i did, i did it wrong because i come up as a standard user now, with no administrator rights. And i cant change my user config because im not an administrator. I cant set up a new user as an administrator either.....just keep getting this message:

And as you can see its asking me for a password with nowhere to type it!!!
Please help!!
