Remove an old shared folder I can no longer access

you know, the owners manual if very vague on how to do all of this.  I just reallized windows by default i guess had my public share folder set to not share.

I set it to share and now everything is visible by the player. 

I cannot get the original folders in my profile to share on the network still like the instructions say to do.

but the public option is ok by me.
