Based on your request, here are the methods to reset or remove the password in Kaspersky Endpoint Security 11.

Note: These methods are typically intended for system administrators who have lost access to the policy settings. You will need local administrator rights on the computer to perform these actions.

Why Standard Password Recovery Fails in KES 11

Unlike consumer antivirus software, KES 11 is designed for enterprise environments. It stores passwords in an encrypted hash using strong cryptographic algorithms (AES-256). There is no "Forgot Password?" link in the management console.

When you enter the wrong password to change settings or uninstall the product, you see:

"Access denied. The password is incorrect."

If you lose the password set via Kaspersky Security Center (KSC) policy, the local KES 11 agent will reject all override attempts. Here is how to regain control.

Summary

  • Managed Network: Reset via Kaspersky Security Center Console.
  • Standalone/Personal: You must contact Kaspersky Support with your license details. There is no local file edit or registry hack that will reset version 11 safely without breaking the installation.

To reset the password for Kaspersky Endpoint Security (KES) 11

, you can use either a specialized tool provided by Kaspersky or a registry modification. Both methods require booting into Windows Safe Mode to bypass active protection. Option 1: Use the Kaspersky Password Reset Tool (KLAPR)

This is the recommended official method for resetting passwords used to close, remove, or configure the application. Download the tool : Download the archive from the official Kaspersky Support page Extract the files : Extract the contents to a folder on your computer. Boot into Safe Mode dialog (Win + R), type , and press tab, check Run the reset Locate the extracted folder and right-click , then select Run as administrator

Follow the command prompt instructions; press any key when prompted. Reboot normally : Repeat the steps to uncheck

and restart your computer. The password protection will now be removed. Option 2: Manual Registry Reset

If the tool is unavailable, you can manually disable the password requirement via the Registry Editor while in Safe Mode. Boot into Safe Mode (see steps above). Open Registry Editor , and press Navigate to the KES settings : Go to the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KasperskyLab\protected\KES\settings Modify the Value Find the DWORD value named EnablePswrdProtect EnablePasswordProtection Double-click it and change the Value data

: Reboot your computer normally. You can now modify settings or uninstall without a password. Managing Passwords via Kaspersky Security Center (KSC)

If your device is managed by a central console, an administrator can reset or change the password remotely: Navigate to Managed devices Right-click the Kaspersky Endpoint Security for Windows policy and select Properties General Settings Password protection to set a new password.

Method 1: The "Exclusive" KLBKARx Tool (Official Kaspersky Recovery)

Kaspersky provides an internal, undocumented utility called KLBKARx (Kaspersky Lab Blowfish Key Administrator Recovery). This is the exclusive method most forums miss.

Step 4: Restart the Service

  • Open Task Manager → Services → Find KAVFS (Kaspersky Anti-Virus File System).
  • Right-click → Restart.

Q1: Can I crack the KES 11 password hash?

A: No. KES 11 uses PBKDF2 with 10,000+ iterations. Brute-force would take centuries. The methods above are the only practical solutions.

5) If you have no access to KSC and many endpoints are affected

Strategy:

  1. Isolate a single test endpoint and perform the local reset/uninstall/reinstall procedure to confirm results.
  2. Use the Kaspersky Admin Recovery tools or agent installer with elevated credentials to re-register endpoints to a new KSC (if migrating).
  3. If endpoints are encrypted or bound to the old KSC, coordinate a phased reinstallation using an automated deployment tool (SCCM, Intune, scripts).
  4. Contact Kaspersky Enterprise Support for bulk recovery options.

Method 1: Using Kaspersky Security Center (For Managed Devices)

If your endpoints are managed via Kaspersky Security Center (KSC) version 11 or higher, the administrator can remotely reset the local password without touching the endpoint.

Steps:

  1. Open Kaspersky Security Center Administration Console.
  2. Navigate to Managed devices → Select the target device.
  3. Right-click the device and choose Properties.
  4. Go to Applications → Kaspersky Endpoint Security 11.
  5. Click Settings → Go to General settings → Password protection.
  6. Check Disable password protection (or set a new password).
  7. Click Save and then Apply to propagate changes to the client.

Note: This method works only if the endpoint still has a network connection to the KSC administration server.

Method 2: The Registry Override (For KES 11.0.0 – 11.2.0)

If the KLBKARx tool fails (e.g., due to newer patch versions), you can reset the password by removing the protected storage registry key. This method works exclusively for versions prior to KES 11.3.
