Hi @Rajesh Kumar

Thank you for contacting Microsoft Q&A Support. 

Based on your description, this following information may help you: 

Option 1: Use the Activation Troubleshooter 

• Go to Settings > System > Activation. 
• Click Troubleshoot. 
• If you see "I changed hardware on this device recently", click it. 
• Sign in with your Microsoft account (the one linked to your digital license). 
• Select your old device from the list and confirm. 

Option 2: If you still have a retail product key 

• Go to Settings > System > Activation. 
• Click Change product key. 
• Enter your 25-character product key. 

Option 3: Contact Microsoft Support, if the above steps don’t work, just let me know in the comment section or seeking the help from Microsoft: 

• Use the Get Help app in Windows or visit Microsoft Support. 
• Explain your situation—they may help re-activate Windows if your license is eligible.
