Use a Third-Party Tool: If you have an existing installation of SQL Server 2012 Enterprise on your server or computer, you can use a third-party tool to retrieve the product key from the registry. There are many tools available online that can scan your system and display the product keys for various software, including SQL Server. Some of the popular tools are [ProduKey], [KeyFinder], and [LicenseCrawler]. However, you should be careful when downloading and using these tools, as some of them may contain malware or viruses.
Extract from Installation Media: If you have the original installation media for SQL Server 2012 Enterprise, such as a DVD or an ISO file, you can try to extract the product key from it. The product key is usually embedded in a file called PID.txt or DefaultSetup.ini, which is located in the root folder or the x86/x64 folder of the media. You can open these files with a text editor and look for the product key. Alternatively, you can use a tool like [WinISO] or [PowerISO] to mount or extract the ISO file and access the files inside.
