1. Re-Activate Windows
- Open Command Prompt as Administrator from WinRE or Safe Mode.
- Run the activation repair command:
slmgr /ato
- If activation fails, use:
slmgr /rearm
- Restart the computer and check if the BSOD is resolved.
2. Repair Licensing Files
- Run the Software Licensing Management Tool:
slmgr /rilc
- This rebuilds damaged licensing configuration files.
- Restart the PC after completion.
3. Roll Back Recent Windows Updates
- Boot into Safe Mode.
- Go to:
Control Panel - Programs and Features - View Installed Updates
- Uninstall the most recent update if the issue started afterward.
- Restart your PC.
4. Restore System Activation Registry
- From WinRE, open Command Prompt and run:
sfc /scannow
- Then use DISM to restore system health:
DISM /Online /Cleanup-Image /RestoreHealth
- These commands restore corrupted activation-related system files.
5. Use System Restore
- Boot into Safe Mode or WinRE.
- Go to:
Troubleshoot - Advanced Options - System Restore
- Select a restore point before the BSOD.
- Complete restoration and restart.
6. Check for Unauthorized Modifications
Uninstall any recent third-party tools that may interfere with Windows licensing, such as:
- Activation bypass tools
- Registry modification apps
- Unauthorized system patchers
- Restart your device after removing them.
7. Rebuild the Licensing Token Store
- Open Command Prompt from WinRE and run:
net stop sppsvc
- Navigate to the store directory:
ren C:\Windows\System32\spp\tokens\*.* *.bak
- Restart the sppsvc service:
net start sppsvc
- Reboot the PC.
8. Reset BIOS/UEFI to Default
- Enter BIOS during startup using Del, F2, or Esc.
- Select Load Optimized Defaults or Restore Defaults.
- Save changes and restart.
- This resolves firmware-related activation mismatches.
9. Verify Genuine Windows Installation
- If Windows is not genuine or activation is blocked, re-enter a valid product key:
- Open Command Prompt and type:
slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
- Replace Xs with your valid key.
10. Perform an In-Place Upgrade or Clean Installation
If licensing corruption cannot be repaired:
- Use the Windows Media Creation Tool.
- Choose Upgrade this PC now to preserve files and fix system components.
- If the issue persists, perform a clean installation after backing up data.
The 0x000000AA (SYSTEM_LICENSE_VIOLATION) BSOD usually arises from licensing corruption, invalid activation states, tampered system files, or hardware changes that invalidate Windows authorization.
To fix this issue effectively:
- Rebuild and repair Windows licensing files using SLMGR tools.
- Restore activation integrity through SFC and DISM.
- Uninstall conflicting updates or unauthorized modification tools.
- Reset BIOS to default to resolve firmware-related mismatches.
- Use System Restore or an in-place upgrade for deep system repair.
If all else fails, entering a valid product key or performing a clean installation ensures proper licensing and complete system stability. Maintaining proper activation and avoiding unsafe software guarantees the prevention of the 0x000000AA BSOD.
