When software comes with a license code, e.g. HXD5S-LB99C-HII54 how does the program know the code is valid without internet validation? For example, some older Microsoft software like Office 2003 could be installed without internet access and you would type in the code and the computer would validate the code. I’ve always been curious about this and the mechanism of how validation occurs.

Depends on the software, but usually there’s a pattern that has to be matched to validate the code… this is baked into the software itself. So if you step through it with a debugger and have lots of patience, you can figure out what the code generating algorithm is and generate your own valid codes.
Most modern registration numbers are hashed against your computer’s UUID and hardware configuration, so you need to find the correct code for your particular system.
