If you already have Windows 8, you can certainly try out this upgrade but be warned that there is no 'Windows Experience Index' or 'Windows Backup' feature.

However if you are on Windows 7, please do not buy Windows 8 or 8.1 to replace your Windows 7 machine. Along with the lost WEI or the backup you lose the start menu, Aero effects, native DVD playback and several things have changed to make the OS more troublesome to use.

If you are running Windows XP and wish to upgrade to a more current system i suggest getting&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Windows-7-Professional-SP1-32bit-Full-System-Builder-OEM-DVD-1-Pack/dp/B004Q0PSMK/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Windows 7 Professional SP1 32bit (Full) System Builder OEM DVD 1 Pack</a>&nbsp;or&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Windows-7-Home-Premium-SP1-64bit-OEM-System-Builder-DVD-1-Pack/dp/B004Q0PT3I/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Windows 7 Home Premium SP1 64bit (OEM) System Builder DVD 1 Pack</a>&nbsp;instead. I will note that you should buy from Amazon directly, not from a seller as it is easy to buy from someone who is not selling a genuine copy.

Those are OEM system builders and while these OS's are tied to the same motherboard i suggest getting these instead of a W8 machine or a copy of W8. Your best bet is to build your own machine, there are tutorials on how to build your own PC and you will have a good chance of saving yourself from a headache, i mean unless of course you happened to like W8 or 8.1 in a store promoting that. I am offering an alternative for those that are too scared to use Windows 8 or 8.1.

There are a few good things about Windows 8/8.1 like multiple apps running side by side, new task manager, and a fast boot. You can also tweak the OS so you can have a start menu by searching for 'classic shell' or 'start menu for Windows 8'. Be aware though that it is not 100% safe as you do not want to download any programs without having an Antivirus protection and listen out to the negative reviews as they can be helpful in making the decision of sticking with Windows 8/8.1.
