Hi and thanks for reaching out. My name is William. I'm a Windows technical expert. I'll be happy to help you out today.
You will need to download Windows 10 2004 64bit using media creation tool. This all-in-one will do the job of downloading the ISO, unpacking it, and creating a bootable Windows 10 media device (usually USB drive) or you can run an in-place upgrade to 64bit.

I suggest you backup all critical or important personal data before doing this.
