Not particularly. There are a lot of scheduled tasks that run under the system context and will get special privileges. That doesn't look particularly abnormal or concerning unless there are details you've left out.

Cliff,
Details would be found where?

Thanks,

This is just noise in the log from normal system functions (usually). You will find this gets logged for any privileged login. System is highly privileged obviously. It could be anything from a batch job, scheduled task or service starting/restarting. The logon ID 0x3e7 is always system. Just before a 4672 event in the security log you should see a 4624 logon event which will list the process that was executing (most likely you will see it is services.exe).

if you are concerned -power off the system at night, it only consumes power...

Even if powered off, windows' task scheduler may wake it up unless all wake functions are disabled.
Windows would like to do updates at night, which you might find a good idea, though.
