Activating your Microsoft Windows operating system is a crucial step to ensure full functionality and access to all features. Whether you’re setting up a new computer or reinstalling Windows, proper activation is essential for a seamless experience.

– OEM key (pre-installed on new devices)
## How to Find Your Windows Product Key
If you’ve misplaced your key, there are several ways to retrieve it:
### For Pre-installed Windows:
Check the Certificate of Authenticity (COA) sticker on your device – usually found on the bottom of laptops or the back of desktop towers.
### For Retail Purchases:
Look for the product key inside the Windows box or in the confirmation email if purchased digitally.

Open Command Prompt as administrator and type: wmic path softwarelicensingservice get OA3xOriginalProductKey
