The way this can be done is by using the default security configuration templates that come with all versions of Windows XP and Vista. This may sound too technical, but all you have to do is run one command.[wp_ad_camp_3]
First, click on Start, Run and then type in CMD. Now copy and paste the following command into the window:
secedit /configure /cfg %windir%repairsecsetup.inf /db secsetup.sdb /verbose
If you are running Windows Vista and need to reset the security settings to their default values, use this command instead:
secedit /configure /cfg %windir%infdefltbase.inf /db defltbase.sdb /verbose
reset local security policy
That’s it! Now just wait for Windows to go through all the registry settings and reset them. It takes a few minutes and you’ll have to restart the computer to see the changes.
But now you should be able to use your computer without any of the remnants of local security settings from previous Group Policies. Enjoy!
