How to Change Windows on PC: A Step-by-Step Guide for Beginners

posted on October 27, 2025

Changing Windows on a PC can seem daunting, but it’s a straightforward process once you know the steps. First, you’ll need to back up your data to ensure nothing gets lost. Then, create a bootable USB drive or DVD with the new Windows version. Finally, insert your installation media, restart your computer, and follow the on-screen instructions to complete the installation. By the end, you’ll have a fresh Windows setup ready to go.

How to Change Windows on PC

Switching to a different version of Windows involves a few key steps. Here’s how you can do it quickly and efficiently.

Step 1: Backup Your Data

Before making any major changes, back up important files to an external drive or cloud storage.

This step is crucial because installing a new Windows version will erase existing data. Ensure everything valuable is safely stored away.

Step 2: Create Installation Media

Use the Media Creation Tool to make a bootable USB drive or DVD with your desired Windows version.

This tool is available on Microsoft’s website and walks you through the process of downloading Windows and setting up the installation media step-by-step.

Step 3: Insert Installation Media

Plug the USB drive or insert the DVD into your PC, then restart the computer.

You’ll need to boot your PC from the installation media. This often requires entering the BIOS or boot menu, which can usually be accessed by pressing a key like F12 or ESC during startup.

Step 4: Install Windows

Follow the on-screen instructions to complete the installation process.

Choose your language, time, and keyboard preferences. Then, select "Install Now" and enter your product key if prompted. You’ll need to choose the partition where Windows will be installed.

Step 5: Set Up Windows

Once installation is complete, go through the initial setup to personalize your new Windows environment.

You’ll be prompted to select settings like your region, login details, and privacy preferences. Once finished, your desktop will appear, ready for use.

After completing these steps, your PC will have the new version of Windows installed. You’ll enjoy improved features and updates, with a fresh start to customize to your liking.

  • Always verify that your PC meets the system requirements for the new Windows version.
  • Keep your product key handy; you may need it during installation.
  • Ensure your USB drive has at least 8GB of free space for the installation media.
  • Check for any driver updates post-installation to ensure hardware compatibility.
  • Use a wired internet connection during setup for a smoother process.
