Perform clean install of Windows 10 (six ways)

 

Do you need to reinstall or set up Windows 10 on a new PC? Check out these six different ways to complete the task.

• KEYPOINTS
• 
  
• To clean install Windows 10, boot PC with a USB bootable flash drive, continue with on-screen directions, skip activation, and select the “Custom” option. Then select the installation drive, click “Next,” and finish the out-of-the-box experience (OOBE).
• Also, you can do a clean installation of Windows 10 with the Media Creation Tool, Reset this PC feature, Advanced startup, or ISO file.

A clean install of Windows 10 is recommended for upgrading to the latest operating system version. The reason is that this method allows you to erase the hard drive and start with a fresh copy of Windows 10 without custom settings, drivers, apps, or files that may interfere with the upgrade process.

If you have had the same installation for a long time, this process can also help fix performance issues, problems shutting down and starting up, memory, and apps. Also, a clean installation is the process of choice to upgrade from an older version like Windows 7 or 8.1. Or you can use this option to delete all preloaded bloatware from the manufacturer image on a new computer.

Whatever the reason, Microsoft offers several ways to perform a clean install of Windows 10, including using a USB flash drive to set up the installation on an SSD (Solid-State Drive). You can use the Media Creation Tool to do a fresh install on a device already running Windows 10. It’s also possible to use the “Reset this PC” feature to quickly wipe out the hard drive and reinstall the operating system without additional tools. Or, if the computer does not start, you can use the Advanced startup options or mount the ISO file to File Explorer to complete a clean install.

This guide will teach you the different ways to perform a clean installation of Windows 10 on your computer, whether you plan to reinstall the same version or upgrade to a later release, including version 22H2, 21H2, 21H1, or 20H2.

Important: This process will delete everything on your device. It’s recommended to make a full backup of your computer before proceeding. You’ve been warned.

Clean install Windows 10 from USB

The best way to complete a fresh installation of Windows 10 is to use a USB flash drive, which you must first create using the Media Creation Tool, Command Prompt, or third-party tools like Rufus. Also, you must ensure the computer can start from USB, which means you may need to adjust the BIOS or UEFI settings. However, since most devices have different settings, you must check your manufacturer support website for more specific details.

To clean install Windows 10 from USB, use these steps:

1. Start the PC with the Windows 10 USB flash drive.

2. Press any key to continue.

3. Click the Next button.

   

4. Click the Install now button.

   

5. Click the “I don’t have a product key” option if you are doing a reinstallation. If Windows 10 was already activated after the installation, reactivation would happen automatically.

   

6. Select the edition of “Windows 10” that your license key activates (if applicable).

   

7. Check the “I accept the license terms” option.

Clean install Windows 10 from Reset this PC (local)

Using the local image, you can also use the recovery settings to start fresh with a clean copy of Windows 10. However, unlike the USB, Media Creation Tool, and ISO file methods, you can only use this option to reinstall the same version of Windows 10 already on the computer. If you want to upgrade to a newer version, you will need to use one of the other alternative methods.

To clean install Windows 10 with the Reset this PC feature using the local image, use these steps:

1. Open Settings.

2. Click on Update & Security.

   • Delete files from all drives: Only the installation drive will be erased if the option is set to No (recommended). Otherwise, if this option is set to Yes, all the drives on the device will be deleted.
   • Download Windows: If this option is set to No (recommended), the local image will be used for installation. If the option is set to Yes, the “Cloud download” option will be activated.

9. Click the Confirm button.

   

10. Click the Next button.

11. Click the Reset button.

    

12. Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).

16. Click the Skip button if you do not need to configure a second layout.

17. The computer will connect to the network automatically if it uses an Ethernet connection. If you have a wireless connection, you must set up the link manually (a security key may be required).

18. Select the “Set up for personal use” option for Windows 10 Pro. (The “Home” edition does not have this option.)

    

19. Click the Next button.

Once you complete the steps, a clean installation will be performed using the local image. If this is a branded computer, the setup will restore all the original settings previously available with the device. This means manufacturer-specific settings, drivers, applications, and tools. If you don’t want to reinstall the custom image provided by the manufacturer, use the “Cloud Download” option (see steps below).

Clean install Windows 10 from Reset this PC (cloud)

Windows 10 also includes the “Cloud Download” option in the “Reset this PC” feature, which allows you to reset the device with a clean installation, removing apps, files, and settings like the local image option. However, the difference is that when you select this option, the setup will download a fresh installation image from the Microsoft server.

This option has been designed to reinstall Windows 10 when the recovery feature is not working with the local image or using a branded computer with a custom image. If you choose this option, the setup will download the same version already installed on the device, which means you cannot use this method to upgrade the computer to a newer version. Also, if the device has a custom image from the manufacturer, this option will replace it with the one from Microsoft with all the standard settings and without custom drivers or trial software and tools.

To reinstall Windows 10 with the Reset this PC using the “Cloud Download” option, use these steps:

1. Open Settings.

2. Click on Update & Security.

3. Click on Recovery.

4. Under the “Reset this PC” section, click the Get started button.

   

5. Click the “Remove everything” option.

   

6. Click the “Cloud Download” option.

   

7. (Optional) Click the Change settings option.

   

8. Configure the reinstallation options: Clean data:

   • Clean data: If this option is set to No (recommended), then the setup will only delete files, apps, and settings quickly. If the option is set to Yes, the setup will securely clean the drive before installing the operating system, but it will take longer.
   • Delete files from all drives: Only the installation drive will be erased if the option is set to No (recommended). Otherwise, if this option is set to Yes, all the drives on the device will be deleted.
   • Download Windows: If the option is set to Yes (recommended), the “Cloud download” option will be activated. If this option is set to No, then the local image will be used for installation.

9. Click the Confirm button.

   

10. Click the Next button.

11. Click the Reset button.

    

12. Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).

15. Click the Yes button.

16. Click the Skip button if you do not need to configure a second layout.

Once you complete the steps, the feature will take over and reset your device to the default settings by erasing and reinstalling a fresh copy of Windows 10 downloaded from the cloud.

Clean install Windows 10 from WinRE

If the computer does not start correctly and you want to reinstall Windows 10 to resolve the problem, the Windows Recovery Environment (WinRE) includes an option to perform a clean installation using the local or cloud image.

Technically, these are the same options available through the “Reset this PC” settings. However, you can also access the feature through the “Advanced startup” option, making it ideal for performing a clean installation of Windows 10 when the computer has problems. Or when you cannot boot the system to access the Settings app. 

Again, you can only use this option to reinstall the same operating system version already installed on the computer. If you also want to upgrade to the latest version, you must use the Media Creation Tool, ISO file, or USB options.

To clean install Windows 10 from the Windows Recovery Environment, use these steps:

1. Start device.

2. Immediately after the Power-On Self-Test (POST), press the Power button again to shut down.

3. Repeat steps 1 and 2 twice, and in the third restart, the operating system should enter the Windows Recovery Environment (WinRE).

   Quick note: Windows 10 has multiple ways to open the Advanced startup settings. You can use these other options if you cannot access the recovery environment.

4. Click the Advanced options button.

   

5. Click on Troubleshoot.

   

6. Click on the “Reset this PC” option.

   

7. Select the “Remove everything” option.

   

8. Click the Cloud download or Local reinstall option. Cloud download: Downloads a fresh image from the Microsoft servers and performs a fresh installation. Local reinstall: Uses the locally available image to install a clean copy of Windows 10.

   

9. Select the “Only the drive where Windows is installed” option. (The All drives option will delete the data on all drives. This option is usually recommended only when you want to decommission the device.)

   

10. Select the “Just remove my files or Full clean the drive” option.

    • Just remove my files: Deletes the drive contents quickly.
    • Full clean the drive: It also deletes everything on the drive but performs a secure erase that takes several hours—this option is suited when preparing to give away the device.

    

11. Click the Reset button.

    

12. Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).

    

13. Click the Yes button.

14. Select your keyboard layout setting.

    

15. Click the Yes button.

16. Click the Skip button if you do not need to configure a second layout.

28. Click the Accept button.

    

29. (Optional) On the “Customize your device” page, select one or more ways you plan to use the device to allow the setup to suggest tools and services customization during this experience.

    

30. Click the Accept button to continue. Or click the Skip button to skip this part of the setup.

31. Click the “No, thanks” button to skip linking your phone to your PC. (You can always do this from the Settings app.)

32. Click the Next button to allow OneDrive to automatically create a backup of your Desktop, Pictures, and Documents folders to the cloud. Or click the “Only save files to this PC” option to skip this step.

    

33. Click the “No, thanks” button to skip the Microsoft 365 setup.

    

34. Click the Decline button to skip the OneDrive storage offer.
