When we buy a new pre-assembled PC, it can happen to find an administrator user already configured inside it, most likely used to be able to configure the operating system and to be able to verify that everything is working correctly before selling. Even with such care we will not have to run into the error of starting immediately to use the PC or our new Mac, since we do not know what the technician or the seller may have configured (he could also have installed an unwanted program or set the graphic effects to the minimum). To be able to regain full control of our computer, in this guide we will show you how to change admin on PC and Mac, so you can start all over again with an administrator user account created by us, with all the parameters reset to default and with a new access password (useful for protecting our computer from unauthorized use).How to change administrator on Windows PC
