Welcome aboard, Palron.
You had a close call. Your elderly laptop is designed for Windows Vista. Even if you do manage to upgrade to 7 or 8, and then upgrade to 10, it probably won't run well on an eight year old machine.
Granted, you have yourself a well-built powerhouse. But technology has advanced enough that a modern operating system will have difficulty running well on your hardware.
Does it still run well? Then I advise you hot to rock the boat.
