Most Windows 10 devices are upgraded to newer versions of the operating system using Windows Update or Enterprise-grade update management solutions.
While that works out fine in many cases, some administrators may prefer (or need) to upgrade using other methods. Common scenarios where this may be preferred are local installations without Internet connection, upgrading multiple PCs, or running into errors when trying to upgrade using Windows Update.
Microsoft provides options to create Windows 10 installation media. You may write the data to an USB Flash Drive or DVD, or run the setup directly from the ISO image that gets created during the process.
The following guide walks you through the steps of installing or upgrading Windows 10 using these methods.
You may use Microsoft's Media Creation Tool to create Windows 10 installation media.
The installation process depends on the installation media.
Option 1: using USB or DVD installation media
This is probably the common option to upgrade a Windows 10 system. You need to have the installation media at hand to perform the upgrade.
Option 2: installing directly using an ISO image
If you don't want to install from USB or DVD, or cannot, you may run setup directly from the ISO image instead. Note that you need to select ISO during creation for that.
