Windows 7 Action Center misreports Security status

Lately I have been bothered by W7 Action Center Alerts...Action Center reports three Important Security issues upon login:

"Spyware and unwanted software protection (Important)
Windows Defender and Norton Security Suite both report that they are turned off."
"Virus protection (Important)
 Norton Security Suite reports that it is turned off."
Network firewall (Important)
Windows Firewall and Norton Security Suite both report that they are turned off."

However, when I open Norton Security Suite all components are reported as "Protected" indicating that they are on and functioning properly. I don't know the reason for this problem but I did find the following procedure on a Norton Forum and this fixed my problem:
==========================================

Sometimes, unregistering and re-registering WMIUTILS.DLL file will fix this issue.

1. Click the Start button, and then click All Programs > Accessories > Run.

2. In the Run dialog box, type the following text:

regsvr32 /u WMIUTILS.DLL

3. Click OK.

4. Restart the computer.

5. Click the Start button, and then click All Programs > Accessories > Run.

6. In the Run dialog box, type the following text:

regsvr32 WMIUTILS.DLL

7. Click OK.

8. Restart the computer.
