Malfunction of Windows Security Center

After uninstalling Microsoft Security Essentials (MSE) v4.2.223.0 from my PC at home running Windows 7 Service Pack 1 Premium (32 bit), error messages following are noted:

1 action Center alerts me to a red X to activate the Windows Security Center.  However, the Windows Security Center service cannot be started on the local computer with error code 5: access is denied.

2. execution of a command - c:\windows\system32\winmgmt/verifyrepository, it shows that the WMI repository verification failed with error code 0 x 80041003 and access denied.

Even I'm trying to re - install my PC with MSE, error code 0 x 80070645 stop and proceed with the installation.

I appreciate it much if any technical advice will be given soon.  I suspect that MSE may have a problem because my home PC is not detected any malware or spyware, Malwarebytes Anti-Malware and SUPERAntiSpyware.
