I bought a accer laptop from my friend and I was trying to find out what the windows Product key was, I went to a site that had me put in some commands into the command prompt and it turned out to be a command to uninstall the product key not a command to show it!!Now I uninstalled my product key, what should i do to get it back without having to purchase a new one?All this just to get windows 10 on it.
vendors like accer have the product number on the laptop itself. look on the bottom or in the battery bay.
