Hey There, I am Sofia Carter. If the HP jumpstart is already on your computer, you do not need to install it. All you have to do is to launch the software and you will be ready to use the services. For HP jumpstart launch, go to the start menu. After that, you will see the HP registration screen appearing where you have to provide the software details so you can start using it. To make the best use of your HP device, you must use the HP jumpstart app or software.
