If for some reason you need to reinstall Windows, Office, or other
Microsoft applications, and you can’t find the original key on a
CD, you’ll be out of luck. You won’t be able to re-install. That
is, you won’t unless you use ProduKey.
The program is exceedingly simple to use. Run it, and it
displays all of your product keys and product IDs for Windows,
Microsoft Office applications, Windows Server, and Microsoft SQL
Server. There are a variety of command line options, if you’d like
to do things such as get product key information from a remote PC,
or save the information to a text file.
Note: This software comes in 32-bit and 64-bit versions.
This is the 64-bit version, which is for 64-bit PCs running a
64-bit OS. If your PC is running a different supported OS, please
32-bit version instead.
