How to Reset Local Security Policy in Windows 11

Resetting the Local Security Policy in Windows 11 can help resolve security-related issues, restore default settings, or troubleshoot problems caused by policy changes. This process restores the security settings to their original state, which can be especially useful if policies have been misconfigured or if you want to start fresh with default security configurations. Before proceeding, ensure you have administrator privileges on your Windows 11 device, as this process requires elevated permissions to make system-wide changes. Additionally, it’s advisable to create a system restore point or back up your current policies, so you can revert if needed.

What You’ll Need

• Administrator access to your Windows 11 PC
• Basic familiarity with Windows settings and Command Prompt

Step-by-Step

1. Open the Search menu by clicking on the magnifying glass icon or pressing the Windows key + S on your keyboard.
2. Type “cmd” or “Command Prompt” into the search bar. Right-click on the Command Prompt app and select “Run as administrator.” This ensures you have the necessary privileges to make system-wide changes.
3. In the Command Prompt window, type the following command to back up your current security policies (optional but recommended):

   secedit /export /cfg C:\BackupSecurityPolicy.inf

   Press Enter. This creates a backup file named BackupSecurityPolicy.inf on your C: drive.

4. Next, reset the Local Security Policy to its default state by executing the command:

   secedit /configure /cfg %windir%\security\templates\classicsecurity.inf /db %windir%\security\local.sdb /verbose

   Press Enter. This command applies the default security template to your system.

5. Wait for the process to complete. It may take a few moments. Once finished, restart your computer to ensure the changes take effect.
6. After rebooting, verify that the security policies have been reset by opening the Local Security Policy editor. Press Windows + R, type “secpol.msc” and press Enter. Review the policies to confirm they are set to defaults.

Common Mistakes

• Running Command Prompt without administrator privileges, which prevents changes from being applied.
• Using incorrect commands or typos, leading to failed resets or unintended modifications.
• Not backing up existing policies before resetting, making it difficult to revert changes if needed.
• Restarting the computer before the reset process completes, potentially leaving policies in an inconsistent state.
• Attempting to reset policies on a non-Windows 11 system, which may not support the commands used.

Tips

• Always run Command Prompt as an administrator for system-level changes.
• Back up current security policies before resetting, so you can restore them if necessary.
• If you encounter errors, verify the command syntax and ensure your Windows updates are current.
• Use the Windows Security and Settings app to manually review or adjust policies after reset.
• Consider creating a system restore point before making significant security policy changes.

Troubleshooting

If resetting the Local Security Policy does not work as expected, or if you encounter errors, try the following steps:

1. Ensure you are running Command Prompt with administrator privileges. If not, close the window and reopen it as an administrator.
2. Verify that the commands are correctly typed, especially the paths and syntax. Typos can cause commands to fail.
3. Check for Windows updates. Sometimes, certain commands require the latest system updates to function properly.
4. If the reset process fails, consider manually restoring policies from your backup file by importing it via the Security Policy editor or using PowerShell commands.
5. Use the Windows System File Checker tool to repair corrupted system files that may hinder policy resets. Open Command Prompt as administrator and run:

   sfc /scannow

6. If all else fails, consider performing a system restore to revert your PC to a previous state before the policy issues occurred.

3. Is it safe to reset security policies on a corporate or managed device?

It’s best to consult your IT administrator before making changes, as resetting policies can interfere with managed security configurations.

4. How often should I reset security policies?

Only when necessary, such as troubleshooting security issues or restoring default settings. Frequent resets are generally not recommended.

5. Can I undo a security policy reset?
