Hi
This isn't exactly what you're asking for, but it may lead you to discover a solution for what you want.
I hide the action center completely using this .reg file
Code:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\{5200400B-EF68-48AD-9E93-5AFC0E6E3E4B}User\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"HideSCAHealth"=dword:00000001
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"HideSCAHealth"=dword:00000001
This is a per-user settings
