Retrieves security event log history using CIM (Common Information Model):

Get-CimInstance -ClassName Win32_NTLogEvent -Filter "Logfile='Security'"

Notes

Clear-History will clear the history, but leaves this command and the ID (command count).

There is also a file that still has your history located here:

C:\Users\<User>\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt

To actually clear the history:

1. Run Clear-History

2. Close PowerShell instances.

3. Delete the ConsoleHost_history.txt file (location above).
