activate windows on new laptop

 

preinstalled windows in harddrive make it work in new laptop

Hi,

I brought my laptop in 2013 with windows 8 preinstalled. Later the device updated to Windows 8.1 and then to Windows 10. Currently am using my laptop with genuine digitally activated windows 10. Recently the laptop has shown serious hardware
issues, the repair person I contacted has suggested me to change my hard drive as early as possible. He said that despite using the activated windows, changing the hard drive will destroy the activated windows & I will have to buy a new copy for the new hard
drive am putting into my laptop. I wanted to know is there some way I can change my hard drive and also don't have to buy new windows OS? Basically I want to know that can I use my activated windows 10 OS into the new hard drive am putting into my laptop.
