A workaround to XP installs when the product key is missinghttp://articles.techrepublic.com.com/5100-10878_11-5034981.htmlsnip-->
When bad software goes goodIn reality, ViewKeyXP is a hacker tool used to reveal Windows XP product keys. But just because it can be used maliciously doesn’t mean that you can’t use it for good.
ViewKeyXP performs a reverse hash on the Product ID that you find in the Registered To box when you right-click My Computer and select Properties. Taking this number, ViewKeyXP deciphers and displays your original product key. You can then write this number down and reinstall Windows XP. When prompted, all you have to do is reenter this number and you’re ready to go.Other Windows software uses product keys, but ViewKeyXP won’t help you find those keys. It works only with Windows XP. However, it will reveal the product key no matter what version of Windows XP you’re running: Home, Professional, or the Corporate Edition.
Obtaining and using ViewKeyXPYou can find ViewKeyXP on the Internet by doing a simple Google Search. Be very careful when you download it. Because it is a hacker tool and not supported by any legitimate organization, don’t be surprised if the version you’ve download has a virus embedded in it. If you choose to download the file, make sure you scan it with an updated virus-scanning program before using it.
In today’s world of setup wizards and multi-megabyte downloads, ViewKeyXP is amazingly simple. The file itself, Viewkeyxp.exe, is small—only 32 KB. There is no installation program. Just run the program, either from the command line or by double-clicking it from the folder you downloaded it to. When you do, your product key will appear as shown in Figure A. (I changed my product key in this image for security reasons.)

ViewKeyXP makes it easy to find your original XP Product Key.
It doesn’t get much easier
That’s all there is to it. Write down the number and then you can reinstall Windows XP, or place the key in a database where you won’t lose it. ViewKeyXP is a handy hacker tool to keep in your software utility toolbox.
