I have set up my computer so that all my work files are on a seperate hard drive. I changed the My Documents folder to point to a directory on this.
I have my own Music folder that I manage, along with the Pictures folder and Videos folder. But Microsoft insist on having a ‘My Music’ folder and a ‘My Pictures’ folder.
I found out how to stop the system creating these folders every time you log on (because I would delete them, then they would return the next day).
Open up regedit, and navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders and change the My Music setting and change it to the path of the folder you want to use. Do the same with My Pictures and My Videos.
