If you would like to see if there were attempts to login and when to local account in windows 10/11 windows has built in feature for that. To enable this feature, you will have to setup the Windows Registry, so Run regedit and navigate to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

If key DisplayLastLogonInfo is there set it to 1. If not create new DWORD (32-bit).with the value 1.

Restart your computer.

Code for key.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"DisplayLastLogonInfo"=dword:00000001

If you would like to disable this feature just do the same thing, but set value of DisplayLastLogonInfo to 0.

Restart your computer.

Have a nice monitoring :)
