Where To Fine Product Keys?

Where are product keys stored in the registry?

  • Recently I started exploring registry and I found the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\UNINSTALL It seems to contain some codes along with software details. I'm wondering if the codes are the product keys I entered during software installation. This http://msdn.microsoft.com/en-us/library/ms954376.aspx says that it's a product code. Is the product code different than the product key? If not, are there different product codes for different license types?

  • Answer:

    The product codes are not product keys, and are not license dependent - they are unique on all the machine. If you explore the registry you will find similar entries for the same software. This entry is added by the Windows Installer. When you go to Control Panel > Add/Remove Programs, the list is populated from this registry key.

{Product Code} in this place is more related to Install/Uninstall technologies (MSI, InstallShield, NSIS, ...) support. It is not related to licensing (although nothing actually prevents an installer to copy some product key here...).
