NOTE:Before applying any changes in the registry always do a system restore or back up your complete registy.
(Backing up your registry------Run-->regedit-->click on computer(leftpane)-->File-->Export-->give a Name -->Save)

If you didn't like the changes after appying the registry tweak...then double click on the backed up registry file and everything reverts back to original as it was.
