Windows – How to find Windows 8 product key

product-keywindows 8

Does anyone know of a way to get the product key that was used to activate Windows 8?

Bonus points for an updated algorithm to extract the product key from the registry key.

While I realize this question has been asked for other versions of Windows, it looks like like many of the older activation key detection tools do not work with Windows 8. Most seem to return strings of the right form (e.g. 5 x 5 characters) but they do not match the actual product key.

UPDATE : This question was originally asked when Windows 8 was first released. It seems most of the tools now handle Win8 properly . . .

I have been using Nirsoft's ProduKey. It works with Windows 8.

ProduKey is a small utility that displays the ProductID and the CD-Key of Microsoft Office (Microsoft Office 2003, Microsoft Office 2007), Windows (Including Windows 7 and Windows Vista), Exchange Server, and SQL Server installed on your computer.
