Method 1. Upgrade Windows 8.1 to 10 Using the Windows 10 Media Creation Tool

Following is the step-by-step guide to Upgrading Windows 8.1 to 10 Using the Windows 10 Media Creation Tool

• The first thing you have to do is, download the Windows 10 media creation tool. You can get this tool from Microsoft's Website. To get the Media creation tool, Click Here.

• After you download the file, open it by double-clicking and click 'Yes' to start the setup tool. This will show you the screen that says, "Getting a few things ready."

  

• Click 'Accept' to agree with the notices and terms when setting up Windows 10 on your computer.

  

• If you want to upgrade directly from Windows 8 to Windows 10, choose the option that says "Upgrade this PC now" and click 'Next.'

  

• The upgrade process from Windows 8.1 to Windows 10 will take some time to finish. Your computer may restart a few times during this process, so just let it happen.

  

• Once the installation is complete, you will see a "Welcome Back" screen. Follow the instructions on the screen to finish setting up Windows 10.

• Now you can choose your Windows settings. If you select the option called "Use Express settings," your computer will load the default settings for Windows 10, which will make it faster to start using.

The old Windows Update prompt for upgrading Windows 8.1 to Windows 10 was part of Microsoft’s earlier free upgrade campaign. In 2026, this option may no longer appear on most Windows 8.1 PCs. Use the ISO file to upgrade instead.

• We do not use Media Creation Tool in this method, so you just get the Windows 10 ISO file directly. Once the ISO has been downloaded, right-click it and choose "Mount".

  

• Open File Explorer and click the newly mounted virtual drive in the left-hand menu. Find and run the setup.exe file to launch Windows 10 Setup.

• Select Keep personal files and apps if you want to move from Windows 8.1 to Windows 10 while preserving your files and installed applications. You may also choose a different option if you prefer not to keep them.

• Click Install to start the upgrade process. After the installation finishes, your Windows 8.1 device will be updated to Windows 10.

You can log in with the same credentials you used for Windows 8.1. Microsoft will then set up your apps and prepare everything for you.
