Windows 11 Troubleshooting Guide: Error 1065 – “The Database Specified Does Not Exist”

Why This Error Happens

Error 1065 typically occurs when a Windows service (commonly WMI, Performance Counters, or a third-party database-dependent service like SQL Server, Windows Search, or an antivirus product) attempts to access its backing database or repository, but the reference is broken. This usually happens due to a corrupted WMI repository, a damaged Performance Monitor counter database, or registry entries pointing to a database file/path that no longer exists (often after an improper shutdown, disk error, or failed update). In some cases, incomplete uninstallation of a service-linked application leaves orphaned registry keys that still reference the missing database.

Step-by-Step Resolution Guide

  1. Identify the affected service
    Open Event Viewer (eventvwr.msc) → Windows Logs → System, filter by Event ID 1065, and note which service triggered the error (e.g., WMI, SQL Server, Windows Search).

  2. Rebuild the WMI Repository (if WMI-related)
    Open Command Prompt as Administrator and run:

   winmgmt /verifyrepository

If it reports as inconsistent, rebuild it:

   winmgmt /salvagerepository

If issues persist:

   net stop winmgmt
   winmgmt /resetrepository
   net start winmgmt
  1. Rebuild Performance Counters (if Perflib-related)
    Run Command Prompt as Administrator:
   lodctr /r

Then restart the WMI Performance Adapter service via services.msc.

  1. Check and Repair Registry References
    Open regedit, navigate to:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<ServiceName>\Parameters

Verify the DatabasePath value points to a valid, existing file/folder. If the path is broken, either restore the missing database file from backup or reinstall the associated application.

  1. Run System File Checker and DISM
    In an elevated Command Prompt:
   sfc /scannow
   DISM /Online /Cleanup-Image /RestoreHealth

This repairs corrupted system files that may be causing the database reference issue.

Alternative or Verification Steps

  • Verify the fix: Restart the affected service via services.msc or reboot the PC, then check Event Viewer to confirm Error 1065 no longer appears.
  • Alternative: If the error persists and is tied to a third-party application (e.g., SQL Server or antivirus), fully uninstall the application, delete leftover folders/registry keys, and perform a clean reinstall to regenerate the database correctly.
