Customize a folder

Hi all,
I am using windows me,
I hope someone can help with this annoying problem.
If I open up "my documents" inside I have 3 folders named My E-books,My Music,and My Pictures.
I can open up anyone of these 3 and by right ckicking in an area inside that folder I have an option to "customize this folder".
If I choose this option the "Welcome to the customize this folder wizard" opens.
I can then replace the boring white background of the folder with a picture.

If I try this with a folder I have created on the desktop e.g. My Photos or Kids stuff , I right ckick ,choose "customize" and get a box appearing saying,"this folder cannot be customized, It is either marked as read only or your system administrator has disabled this functionality .Contact the administrator".
I have checked the properties of the folders and they are not marked "read only"
How can I contact the administrator ? Only myself and my kids use the computer and as far as I know I never set up an administrator!!
Any Ideas please?

 

Try checking the box that says "Archive"

??? Hope it helps.
