If it's an OEM license that came with the laptop when you bought it, it's tied to the machine and dies with the machine. So then the value is exactly 0.
If it's a retail version, it's not worth much, since nobody wants Vista since Windows 7 came out in 2010.
I have a laptop installed windows vista original and has a license, but my laptop is broken. I intend to sell licenses vista windows I have. question: where can I sell it and how much can I market?
besides how good deal if you get a buyer. I expect any help, advice or opinions about my problem.
