Your organization has finally made the jump, and deployed Internet Explorer 7 to the general populace. However, there are a few of the employees that do not quite get the idea of tabbed browsing. It just confuses them more.
Luckily, you as a system administrator, can remotely disable tabbed browsing through a registry tweak. Sure, you could simply walk them through unchecking the checkbox in the GUI, but it’s much more geeky to do it through the registry.
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\InternetExplorer\Tabbed\Browsing]
"Enabled"=dword:00000000
Using the registry tweak will also force the change on users, meaning they cannot turn tabs back on by themselves. You must undo the change for them, by changing the 0 to a 1.
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\InternetExplorer\TabbedBrowsing]
"Enabled"=dword:00000001
