4. Right-click the ProductId key and select Modify. View the number displayed. This is your product key for Windows. Press the 'Cancel' button to avoid making changes to the value.

Option 2: Find Windows 8 new product key from Microsoft

If the above couldn't help you, we need to ask for Windows 8 replacement product key from Microsoft. But at first you have to make sure Windows 8 version you are using. Is it Windows OEM version? If it is, you have to call the support department of your PC vendor first.

If your vendor cannot solve your problem, then you should go to Microsoft support and ask them for Windows 8 replacement product key.

Now activate Windows 8 new product key in command prompt:

1. Open the command prompt as administrator (when opened as admin the prompt will be at 'c:windowssystem32').

2. Uninstall the present Product Key (if any) by typing this 'slmgr /upk'.

3. Now install the new Product Key by typing this command 'slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX'. This command will replace the X's with the Windows 8/8.1 key.

A message should pop up to notify you later that new product key has been installed. You can verify it by refreshing and checking the systems properties page. Hope your problem has been solved.

Option 3: Find Windows 8 product key with third-party software

Surely, above two ways work sometimes. But whether there is another way more easily and effectively to find Windows 8 product key? The answer is yes. iSunshare Product Key Finder is such third-party software used to find forgotten or lost product keys for installed software programs, including Windows, Office, SQL Server, IE, Adobe etc.
