What is 0x00000006 Error?


Error Code 0x00000006, also known as "INVALID_HANDLE", indicates that a program or process attempted to access a handle (such as a file, registry key, or device reference) that is either invalid, has already been closed, or was never properly initialized. This low-level system error can result in software crashes, service interruptions, or even Blue Screen of Death (BSOD) in more severe cases. It is commonly seen in legacy software, printer processes, outdated device drivers, and certain background services.

Causes

  • Corrupt or Closed Handles: Applications or drivers sometimes improperly reference a handle that no longer exists or has been disposed of too early.
  • Outdated or Incompatible Device Drivers: Drivers with poor handle management can trigger this error when interacting with the system or hardware.
  • Malfunctioning Applications: Some apps may include code that doesn’t properly manage system resources, especially after an OS update.
  • Registry Misconfigurations: Corrupted registry entries pointing to invalid handles or system references can cause handle-related errors.
  • Malware or Intrusive Security Software: Malicious programs or even overzealous security software can interfere with handling creation and destruction.

Resolution Steps




1. Restart Your PC

Simple but effective—this can clean up any lingering invalid handle references caused by previous sessions.

2. Update All Device Drivers

  • Open Device Manager.
  • Right-click each important device (especially display, network, and chipset drivers) → Update Driver.
  • Consider uninstalling and reinstalling drivers from the manufacturer’s website for better stability.

3. Run System File Checker and DISM

These tools scan and repair corrupted system files and the Windows image:

sfc /scannow

DISM /Online /Cleanup-Image /RestoreHealth

4. Boot Into Safe Mode

If the issue persists in normal mode, try booting into Safe Mode.

  • Type msconfig → Boot tab → Enable Safe boot → Restart.
  • This helps isolate third-party interference.

5. Clean Up Registry

Use a trusted tool (like CCleaner) or a manual registry backup and fix approach:

  • Press Win + R, type regedit.
  • Backup the registry (File → Export), then search for invalid entries related to faulty apps or devices.

6. Perform a Clean Boot

  • Type msconfig → Services tab → Hide Microsoft Services → Disable All.
  • Restart and test if the error disappears.
  • Helps identify problematic third-party software.

7. Run a Full Malware Scan

  • Use Windows Defender or third-party tools like Malwarebytes.
  • Malware may create fake handles or corrupt the system’s ability to manage them.
