Want to lock the Internet Explorer toolbars so they can not be moved by click-and-drag? The following registry hack works for all windows versions including Windows NT, Windows 2000 and Windows XP:

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Internet Explorer\Toolbar
Name: Locked
Type: REG_DWORD
Value: 1=locked;0=unlocked

You have to restart IE for this to take effect.
