Reinstall Windows 11 & Keep Activation with MAS

Worried about losing your Windows 11 activation after a fresh reinstall? This guide explains how Microsoft Activation Scripts (MAS) can help you maintain your licensed status, ensuring a smooth transition.

Reinstall Windows 11 and Keep Activation: A Guide with MAS

Many users wonder about the process to reinstall Windows 11 and keep activation. The good news is, for genuinely activated systems, Microsoft often ties your license to your hardware (Digital License/HWID). This means a clean install on the same machine usually reactivates automatically. However, for those using alternative activation methods, or simply wanting peace of mind, Microsoft Activation Scripts (MAS) offers robust solutions.

How MAS Helps Preserve Your Activation

MAS provides several methods that can help you reinstall Windows 11 and keep activation. If your system was activated using MAS's Digital License (HWID) method, your activation is permanently tied to your hardware. A fresh install will automatically detect this and reactivate. For other scenarios, MAS's Ohook and Online KMS (KMS38) methods also offer persistent activation. Ohook integrates deeply for long-term activation, while KMS38 provides a 10-year activation, both generally surviving reinstalls if the correct version of Windows is installed.

Getting Started with Microsoft Activation Scripts

To ensure you can reinstall Windows 11 and keep activation, it's always best to have MAS on hand. Simply visit our download page. You might need to temporarily disable your antivirus software, as MAS scripts can sometimes be flagged due to their nature. Once downloaded and extracted, follow the clear instructions provided to activate your system. This proactive step ensures your activation remains intact, even after a complete system overhaul.
