It happens to us all. You deleted your My eBooks, My Videos, and My Music folders only to open up the same folder a few minutes later and find they had in fact not been deleted after all. It is time to get rid of them for good.
Go to Start > Run > type "Regsvr32 /u mydocs.dll" and press enter.
Press OK on the new dialog box.
Go into My Documents and delete any of those "My" folders you want, they're not coming back!
