I'm considering upgrading my current operating system to Windows 10. I've been browsing online, and I've noticed a variety of prices for Windows 10 licenses. Can anyone share insights on the typical cost for a genuine Windows 10 license? Also, are there different versions with varying prices (like Home vs. Pro), and what are the main differences between these versions? Lastly, is there any advantage in buying directly from the Microsoft Store versus other retailers or online marketplaces? Any advice or experiences would be greatly appreciated!
