Microsoft provides generic product keys for Windows 8.1, which can be used during installation but have limitations and are not a substitute for a proper product key:
: Creating a small text file named ei.cfg and placing it in the \sources folder of your installation USB allows you to skip the key prompt entirely during setup. Technical & Unofficial Methods (Use at Own Risk)
: You can install Windows 8.1 without a key by creating a configuration file named ei.cfg in the \Sources folder of your installation media. This allows you to select your edition and proceed to a trial period, but you must still provide a key later for full activation.
