I am trying to cleat all the events in my event viewer as I had so many errors in the past 7 days. I opened powershell & ran as administrator & use this command

wevtutil el | Foreach-Object {wevtutil cl $_}

& I had some access denied errors.

PS C:\Windows\system32> wevtutil el | Foreach-Object {wevtutil cl $_}
Failed to clear log Microsoft-Windows-LiveId/Analytic. Access is denied.
Failed to clear log Microsoft-Windows-LiveId/Operational. Access is denied.
Failed to clear log Microsoft-Windows-USBVideo/Analytic. The instance name passed was not recognized as valid by a WMI data provider.

Is this normal? I still see the history last 24 hours & 7 days says still.
