It depends on what criteria the company that is creating the trial license is using.
We create software licenses based on the serial number of the Hard Drive and the BIOS name (type) of the machine.
So, you could take the drive and move it between machines, and it'll continue to work as long as you move it to the same type machine. But, copy it to a new drive, it will fail.
Microsoft utilizes multiple options.. If one changes, it'll continue to work (Speaking towards Windows) but if multiple items change, they'll lock it down.
old software on windows xp it was possible hack for changing the MAC or system time.
Yea, but those types of weak, single point of attack, mechanisms have pretty much gone away (unless the developer really doesn't care).
We generally use a hardware dongle with our products, but with demos we create a set of unique identifiers at first run that tie pretty firmly to the machine. With enough work you could roll back a disk image and reuse the software for another period, but you'd have to change several things to get another activation from our server: Among other things we use info from the UUID (mother board specific, but not always present), HDD Serial Number, CPU Serial Number, and the Windows Product ID (itself derived from the software key, hardware info, install date, etc).

Can you provide finger-print protection? Hackers cant clone people fingers yet!

We've worked with finger print readers (for employee log-in, not licensing), so we theoretically could, but they have been hacked / hack able for a long time.
The machine ID is given by a software I downloaded to my computer for free 7 day trial.
I would like to trial the software a few more days.
But each time I re install the software, the machine id remains the same which blocks me from trial the software again.
So I am trying to see how to change the machine id.
Have you tried to contact the vendor for a longer trial, I have found they usually help you.
