However, the special Music shell folder had lost its shiny blue icon and was now an ordinary yellow folder. I guessed the problem was with the hidden system file desktop.ini but even though I took a copy of this file from the undamaged Admin user account and pasted it into Stuckling1's Music folder, his folder stayed yellow.

I couldn't find anything here in the The Lounge about this problem but a quick Google led me to this tutorial:

As it did the trick and Stuckling1 has his nice Aero blue Music folder back again I thought it would be handy to have it mentioned here, others are bound to need it sometime!
