I don't like Windows 10 at all, as it is very intrusive. There are always some updates that come out, because of which my computer does not want to work normally and constantly freezes. It is best to download Windows 7, it is freely available on https://limitlessreferrals.info/windows-7-pro-oa-download-with-a-product-key-oem/. I've been using Windows 10 for a while and decided to go back to Windows 7, as some of the keys on my keyboard stopped working due to updates. I would recommend you to install Windows 7, for the reasons I mentioned above.
