Deleting a Kaspersky license key directly from the Windows Registry is generally not recommended by Kaspersky Support because it can lead to application instability or "orphaned" entries that prevent re-activation . Instead, the standard and safest method is to use the application's built-in interface or the official removal tool. Method 1: Delete via Kaspersky Application Interface (Recommended) This is the standard way to remove a key so you can enter a new one. Open your Kaspersky application (e.g., Kaspersky Plus, Total Security). Go to the Licensing or Subscription section (usually found at the bottom-right or in the Settings gear icon). Locate your current license/key and click Delete (trash can icon) or Remove . Confirm the deletion when prompted. Method 2: Manual Registry Cleanup (Advanced) If you are unable to open the application or need to clear "ghost" license info, you can check these common registry locations. Warning: Back up your registry before making changes. Press Win + R , type regedit , and hit Enter . Navigate to the following keys (depending on your Windows version): HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KasperskyLab\ (64-bit Windows) HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\ (32-bit Windows) Search for sub-folders like Licensing or values named PCID . If a password prompt prevents you from editing these, you may need to find the EnablePswrdProtect value and change it from 1 to 0 while in Safe Mode . Method 3: Use the Kaspersky Removal Tool (kavremover) If manual deletion fails, the official kavremover utility is designed to scrub all licensing and registry data that standard uninstallers leave behind.
Deleting a Kaspersky license key from the registry is a deep-level technical process usually reserved for troubleshooting activation errors or performing a clean uninstallation when the standard interface fails. Before attempting manual registry edits, you should always try removing the license through the official Kaspersky application interface or the kavremover tool . Precautions Before Editing the Registry The Windows Registry is a sensitive database. Deleting the wrong key can cause system instability. Backup the Registry : Export any keys before deleting them so you can restore them if needed. Disable Self-Defense : Kaspersky protects its own registry entries; you must disable this feature in the app settings first, or the registry will block your changes. Boot into Safe Mode : For the most reliable results, perform these steps in Windows Safe Mode to prevent Kaspersky processes from actively using the keys. Step 1: Locate Kaspersky Registry Keys License information and activation data are typically stored in specific "environment" or "LicStorage" folders within the registry. Common Registry Paths: 64-bit Systems : HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KasperskyLab\protected\AVP[Version]\environment\ 32-bit Systems : HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\protected\AVP[Version]\environment\ Other Storage : HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\protected\LicStorage\ Note: Replace [Version] with your specific version number (e.g., AVP21, AVP11).
