Win 8 Pro- How To Force All Apps Screen To Refresh

I am currently running a 64 bit version of Windows 8 Pro with all available MS updates applied to it.

I have the need to change the name of one of the program groups that appear on the All Apps screen.

Let's say the group name is "Test". And I want to change the name to "Answer".

I navigate to the Desktop interface.

I go to: C:ProgramDataMicrosoftWindowsStart MenuPrograms

I rename the folder "Test" to "Answer"

I navigate back to the Metro interface.

I open the All Apps screen, but I still "see" the group named "Test".

Even if I log out and log back on. Or. if I log on as a different user.

Is there a way for me to force Windows 8 to update the All Apps screen ?

By the way ........

The above folder has a shortcut in it that points to Notepad.exe.

If I follow the same procedure (above) to rename the shortcut inside of the folder, the new shortcut name appears immediately when I return to the All Apps screen.

It's only the group name, that is not refreshing on the All Apps screen. (For some reason.)
