Fix Windows Services

Is your Microsoft Activation Script (MAS) encountering errors due to problematic Windows services? This guide provides clear, actionable steps to diagnose and resolve common service-related issues. We'll walk you through fixing corrupt 'sppsvc' and 'Null' services, ensuring your activation process runs smoothly and without interruption.

Corrupt service - sppsvc

  • Follow the steps below only if the script shows that sppsvc service is corrupt. Do not follow otherwise.
  • Download and extract the sppsvc registry file.
  • Run the file, restart the system (using the restart button), and try the activation script again.
  • If the issue persists, contact us here.

Corrupt service - Null

  • The script may show that Null service is not running, script may crash...
  • Follow these steps only if the script crashes after that.
  • Download and extract this Null service registry file.
  • Run the file, restart the system (using the restart button), and try the activation script again.
  • If the issue persists, check if you are using Comodo Antivirus or any type of sandboxing security software. If so, temporarily disable it and run the script again.
  • If the issue persists, contact us here.
