The file getfn32.dll, known as Windows Serial Number Checker, belongs to software Windows Serial Number Checker. In Windows 7, the Serial Number or Serial Key, which is technically a product key, is encrypted in the Windows Registry making it nearly impossible to find manually. The product key is necessary in the event of system crash and the software has to be reinstalled in the computer. The easiest way to find the serial key is to use a product key finder program that will automatically search the computer for the serial key. The Windows Product Key Finder is a small utility that enables the user to find out the Windows Product key, if the program CD case that contained the serial number cannot be located. This freeware is built in C+, and requires a system with .NET 2 installed. This application works in Windows XP, Vista, and Windows 7, and does not require any installation since only a single executable file is contained in the program.
