Where to see PC code 20 on the computer

The machine code is usually a string of characters compiled by the software to be registered according to your hardware (such as CPU, hard disk identifier, and some according to the operating system) in its own encoding.

Usually the machine code is only used when some software is registered, for PC users.

Machine codes don't exist!

That's just a set of numbers obtained by software vendors to prevent piracy and sell the right to use software, so as to use a software developed by themselves to make some undisclosed calculations on the hardware identification code of your machine, which is only useful to the manufacturer itself.

As for how to know your machine code, you should open the software registration window to see it.

You won't be able to find out your computer's hardware code. Hardware ** appears on some shareware, in order to make you pay to register, the author made an encryption program, in which the program identifies the hardware installed on your computer, and then calculates a string of hardware**, and then the author's decryption program converts ** into a registration code. If you use this registration code on another computer, because the hardware on the two computers is not exactly the same (not according to a simple configuration, for example, the hard disk is 40G, but the hard disk number, serial number, etc. are different), so the hardware of the other computer is also different, and it cannot be registered for use.

Due to the different keygen program designs used by the software authors, the same computer uses different algorithms to obtain different hardware**, so the risk of being cracked is reduced.
