Comments:

I always recommend you to buy the latest OS and every software you install on your computer to avoid any attacks on your computer as with time OS gets older and its security features do not remain effective as of latest OS.

And one more thing never purchases OS from third-party websites. Always buy genuine products from Microsoft store only.
