Have a couple of questions .

1, I picked up a HP laptop that has windows 10 . What I need to know is how can I do a clean install ! Do I need the serial key numbers ?

2. I usually run my resolution at 1024x768 for general . But the screen is squeezed on each side with black boxes . How can this be fixed .

Thanks in advance .

 

Just download the latest W 10 ISO and make a bootable media.Use the Media creation tool and after installing, the OS will querry the digital licence tied to the laptop and activate itself on-line.After that it will pick the right video driver and solve the resolution issue.

 

What model notebook exactly? Is it an old one?

 

What does the windows sticker on the back of the laptop say ?

 

A shot in the dark.
IF the laptop had Windows 10 installed on it and activated, it has now a digital licence tied to the whole laptop.Even so, if now one installs Windows 10 and put a valid OEM Windows 7 licence, it will activate.Did this many, many times and still works.
By now, the laptop may also upgraded to Windows 10 (vast majority did), it is just a matter of installing on it and that's it.
About the resolution, the image being squeezed brings back to my memory a certain HP model with older integrated Intel graphics.Solved the issue after installing with the newest driver and problem solved.

 

Sorry to take so long to get back, but things went haywire . Thanks for the help .
