Windows ships with a few default folders, which is a good thing – You should try and keep your folders organized! The problem is that I don’t use the My eBooks folder, it just sits there, empty and cluttering up my My Documents folder. I delete it, but it keeps coming back when I restart my machine! 
If that angers you too, then keep reading, this little Windows hack will let you delete the default folders like My eBooks, My Videos & My Music once and for all!

How To
Hit the Windows Key+R, then type:
Regsvr32 /u mydocs.dll
Go to your My Documents folder and delete any of those “My” folders you don’t want! That’s it, all done!
What It Does
From Wikipedia:
regsvr32.exe is a command-line utility in Microsoft Windows operating systems for registering and unregistering DLLs and ActiveX controls with Windows.
To be used with regsvr32.exe, a DLL must export the functions DllRegisterServer and DllUnregisterServer.
Usage
Regsvr32 [/u] [/n] [/i[:cmdline]] dllname
/u – Unregister server
/i – Call DllInstall passing it an optional [cmdline];
when used with /u calls dll uninstall
/n – do not call DllRegisterServer;
this option must be used with /i
If you don’t know what this stuff is then don’t get to into crazy using them, just run the one I have shown you!
