How to Upgrade to Windows 10, using Windows 10 ISO

Microsoft has made available the Windows 10 ISO for download. In our last post we saw how you can use Windows 10 Media Creation Tool to create an Installation media. In this post, we will see how to use this Windows 10 ISO to upgrade your Windows 8.1 or Windows 7 computer to Windows 10.

If you upgrade to Windows 10, the new OS will take the product key and activation details from your earlier OS. These are then saved on Microsoft servers, along with your PC details.

If you clean install Windows the first time, you may face activation problems. If you performed an upgrade the first time, activated Windows 10, and then clean installed Windows 10 on the same PC, then there will be no activation issues, as the OS will pull activation details from Microsoft servers.

So, if your Windows 10 isn’t activated, we suggest you not perform a clean install the first time. First Upgrade, Activate and then Clean Install.

You might want to first backup your important data to an external drive before you proceed with the upgrade  process. Also make sure you have Windows login password ready. And although you wont need it during the upgrade process, it might be a good idea to find and down your Windows product key somewhere.
