Windows Key Activation Guide

# Windows Key Activation Guide
## Understanding Your Microsoft Windows Key
Your Microsoft Windows key is a unique 25-character code that verifies your copy of Windows is genuine. This product key typically comes in one of these formats:
– Retail purchase (boxed copy)
– OEM key (pre-installed on new computers)
– Digital license (linked to your Microsoft account)
## How to Find Your Windows Key
### For Pre-installed Windows:
Most modern computers store the key in the BIOS/UEFI firmware. You can retrieve it using these methods:
- Check the Certificate of Authenticity sticker on your device
- Use PowerShell command:
powershell "(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey"
### For Retail Copies:
Your key will be:
- On the product card inside the Windows box
- In the confirmation email if purchased digitally
- On the DVD case if included
## Activating Windows with Your Key
During Installation:
When installing Windows, you’ll be prompted to enter your product key. You can choose to enter it immediately or select “I don’t have a product key” and activate later.
After Installation:
- Open Settings > Update & Security > Activation
- Click “Change product key”
- Enter your 25-character key
- Follow the on-screen instructions

## Troubleshooting Activation Issues
If you encounter problems activating Windows:
- Verify you’re entering the correct key (watch for similar characters like 0/O or B/8)
- Check your internet connection
- Contact Microsoft Support if you receive error messages
- For OEM keys, ensure you’re using the correct Windows edition that came with your device
## Digital License vs. Product Key
Modern Windows installations often use a digital license tied to your Microsoft account or hardware. This means:
- No need to enter a key after major hardware changes
- Automatic reactivation when reinstalling on the same device
- You can view your digital license status in Settings > Update & Security > Activation
## Important Notes
Remember these key points about Windows activation:
- Each product key can only activate one device at a time
- Microsoft doesn’t provide replacement keys for lost retail copies
- Beware of third-party key sellers offering suspiciously low prices
- Volume license keys require special activation methods
