The Local Security Policy app is an advanced configuration tool to control various security aspects of the operating system. Like Local Group Policy, it is implemented as a Microsoft Management Console (MMC) snap-in. If you need to reset all its settings, here is a single command which can revert them to default in a moment.
Local Group Policy editor can be launched by typing secpol.msc in the Run dialog. 
It has a lot of settings related to the local device or network resource protection. Note: home editions of Windows 10 come without this useful tool. It is available only in Windows 10 Pro, Enterprise, and Education editions.
Some day, you might want to reset the security policy settings you have configured in Windows 10. It is a very long process to do it one by one if you have changed many settings. There is a way to quickly reset all Local Security Policy Editor settings back to the defaults. Here is how it can be done.
- Open an elevated command prompt.
- Type the following command:
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
- Restart your Windows 10 PC.
You are done. This trick also works in Windows 8, Windows 7 and Windows Vista.
