Without a product key being labelled, is there is any way to identify what Microsoft software product a given product key is meant to activate?
Let's say for example I had the product key ABCDE-FGHIJ-KLMNO-PQRST-UVWXY, but I had no clue if was meant for Windows 7 Ultimate, Windows 7 Home Premium, Vista Ultimate, or even Office 2010. Is there a way I identify the software product the key is meant for (or at least get a good estimate)?
Note: I have searched and searched many times on the Internet, but the only results I ever find are how to recover a lost product key by using something like Nirsoft ProduKey. This is not what I am looking for.
