PLEASE READ THIS NOTE CAREFULLY:
If you are looking for someone to provide you with a product key for Microsoft Windows or Office, because you’re using a pirated copy or you lost the key that came with your legally purchased copy, I CANNOT HELP YOU. I’ve locked this entry for comments, because too many people seem to think that it’s OK to post here asking for this information. It’s not.
However, if you have a legally installed copy of Windows XP or most versions of Office and you’ve lost the product key, this page can help. This 25-character code, which is impossible to memorize unless you’re The Amazing Kreskin, is required if you need to reinstall Windows. Normally, it’s found on the holder for your Windows CD. If you lost the CD case, you’re locked out. But help is finally available. You can dig up this value from the Registry using a cool tool called Keyfinder, from Magical Jellybean Software. It works with every version of Windows, and with Office 97 and Office XP (but not with Office 2000). Best of all, it’s free.
Note that this software works ONLY if you have Windows or Office already installed and activated using a legal product key. If the software isn’t installed, you’ll have to call Microsoft and explain that you lost the key.
