Hello,
I have this old HP G62 that was on Windows 7 Ultimate. I recently upgraded it to Windows 8.1, and it's working fine.
Now, I want to upgrade to Windows 10, but I'm not sure if the computer can handle it.
Your processor is too old. So windows 10 does not officially.
Don't upgrade to windows 10. For better performance keep it up to windows 8.1 or windows 7 only.
If you upgrade your computer. Then build your pc with atleast intel i5 12th processor based pc
