Perform clean install of Windows 10 (six ways)

To perform a clean install of Windows 10, boot the 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).
You can also clean install Windows 10 with the Media Creation Tool, Reset this PC feature, Advanced startup, or ISO file.

UPDATED 8/2/2024: A clean install of Windows 10 is the only option for setting up a new computer and the recommended process for upgrading to the latest operating system version. 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.

Personally, I use a clean installation after having the same setup for a long time (usually a year) since it can also help to fix performance issues, problems shutting down and starting up, memory, and apps. This process is also the best choice for upgrading from an older version (such as Windows 7 or 8.1) or downgrading from Windows 11. You can also use this option to debloat the system that may have come preinstalled with the manufacturer’s image on a new computer.

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) or HDD (Hard Disk 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 Windows Recovery Environment (WinRE) or mount the ISO file to File Explorer to complete a clean install.

In this guide, I’ll teach you the different ways to perform a clean installation of Windows 10 on your computer, whether you plan to reinstall the same version, upgrade to a later release, including version 22H2 or 21H2, or set up a new custom build PC or after replacing the hard drive on your device. (The process is similar for older versions, such as 21H1, 20H2, 1909, 1903, 1809, 1803, 1709, and others.)

Clean install Windows 10 from USB
Clean install Windows 10 from Media Creation Tool
Clean install Windows 10 from Reset this PC (local)
Clean install Windows 10 from Reset this PC (cloud)
Clean install Windows 10 from WinRE
Clean install Windows 10 from ISO file

Important: This process will erase everything on your computer. It’s recommended that you 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 confirm your computer meets the minimum system requirements and ensure it can start from USB by changing the boot order in the motherboard’s firmware, 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:

Start the PC with the Windows 10 USB flash drive.
Press any key to continue with the installation setup.
Click the Next button.
Click the Install now button.
If you are reinstalling, click the “I don’t have a product key” option. If Windows 10 was already activated after the installation, reactivation will happen automatically.
Select the edition of “Windows 10” your license key activates (if applicable).
Check the “I accept the license terms” option.
Click the Next button.
Select the “Custom: Install Windows only (advanced)” option to perform a clean install.
Select each partition on the hard drive where you want to install Windows 10 and click the Delete button. (Usually, “Drive 0” is the drive that contains all the installation files.)

Warning: Deleting a partition also deletes all data on the drive. Also, it is not necessary to delete the partitions from a secondary hard drive.
Select the hard drive (Drive 0 Unallocated Space) to install Windows 10.
Click the Next button.
Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).
Click the Yes button.
Select your keyboard layout setting.
Click the Yes button.
Click the Skip button if you do not need to configure a second layout.
The computer will automatically connect to the network using an Ethernet connection. If you have a wireless connection, you must set up the connection manually (a Wi-Fi password may be required).
Select the “Set up for personal use” option for Windows 10 Pro. (The “Home” edition does not have this option.)
Click the Next button.
Confirm your Microsoft account email to create an account.

Quick tip: You can set up Windows 10 without a Microsoft account with these instructions.
Click the Next button.
Confirm your account password. (You can also use the Microsoft Authenticator app to sign in.)
Click the Next button.
Click the “Create a PIN” button.
Create a new PIN password.
Click the OK button.
Click the “Now now” button to skip importing your browsing data from other browsers to Microsoft Edge.
Turn on or off the toggle switch for each option to confirm the privacy settings that best suit your needs.
Click the Accept button.
(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.
Click the Accept button to continue. Or click the Skip button to skip this part of the setup.
Click the “No, thanks” option from the bottom-left corner to skip linking your phone to your computer.
Click the “Not now” button to disable Cortana.

Once you complete the steps, Windows 10 will apply the settings and finish the setup.

Click the Next button.
Confirm your Microsoft account email to create an account.
Click the Next button.
Confirm your account password. (You can also use the Microsoft Authenticator app to sign in.)
Click the Next button.
Click the “Create a PIN” button.
Create a new PIN password.
Click the OK button.
Click the “Now now” button to skip importing your browsing data from other browsers to Microsoft Edge.
Turn on or off the toggle switch for each option to confirm the privacy settings that best suit your needs.
Click the Accept button.
(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.
Click the Accept button to continue. Or click the Skip button to skip this part of the setup.
Click the “No, thanks” option from the bottom-left corner to skip linking your phone to your computer.
Click the “Not now” button to disable Cortana.

After you complete the steps, the setup will continue with the fresh installation of the operating system.

This video tutorial will walk you through every step to successfully install the operating system on your computer.

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 the operating system 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:

Open Settings.
Click on Update & Security.
Click on Recovery.
Click the “Get started” button under the “Reset this PC” section.
Click the “Remove everything” option to perform a fresh install of Windows 10.
Click the “Local reinstall” option.
(Optional) Click the Change settings option.
Configure the reinstallation options:
- Clean data: If this option is set to “No” (recommended), the setup will only quickly delete files, apps, and settings. 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: If the option is set to “No” (recommended), only the installation drive will be erased. 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.
Click the Confirm button.
Click the Next button.
Click the Reset button.
Click the Next button.
Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).
Click the Yes button.
Select your keyboard layout setting.
Click the Yes button.
Click the Skip button if you do not need to configure a second layout.
The computer will automatically connect to the network using an Ethernet connection. If you have a wireless connection, you must set up the connection manually.
Select the “Set up for personal use” option for Windows 10 Pro. (The “Home” edition does not have this option.)
Click the Next button.
Confirm your Microsoft account email to create an account.
Click the Next button.
Confirm your account password. (You can also use the Microsoft Authenticator app to sign in.)
Click the Next button.
Click the “Create a PIN” button.
Create a new PIN password.
Click the OK button.
Click the “Now now” button to skip importing your browsing data from other browsers to Microsoft Edge.
Turn on or off the toggle switch for each option to confirm the privacy settings that best suit your needs.
Click the Accept button.
(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.
Click the Accept button to continue. Or click the Skip button to skip this part of the setup.
Click the “No, thanks” option from the bottom-left corner to skip linking your phone to your computer.
Click the “Not now” button to disable Cortana.

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 when a branded computer with a custom image is used. 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:

Open Settings.
Click on Update & Security.
Click on Recovery.
Click the “Get started” button under the “Reset this PC” section.
Click the “Remove everything” option.
Click the “Cloud Download” option.
(Optional) Click the Change settings option.
Configure the reinstallation options:
- Clean data: If this option is set to “No” (recommended), the setup will only quickly delete files, apps, and settings. 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: If the option is set to “No” (recommended), only the installation drive will be erased. 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.
Click the Confirm button.
Click the Next button.
Click the Reset button.
Click the Next button.
Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).
Click the Yes button.
Select your keyboard layout setting.
Click the Yes button.
Click the Skip button if you do not need to configure a second layout.
The computer will automatically connect to the network using an Ethernet connection. If you have a wireless connection, you must set up the connection manually.
Select the “Set up for personal use” option for Windows 10 Pro. (The “Home” edition does not have this option.)
Click the Next button.
Confirm your Microsoft account email to create an account.
Click the Next button.
Confirm your account password. (You can also use the Microsoft Authenticator app to sign in.)
Click the Next button.
Click the “Create a PIN” button.
Create a new PIN password.
Click the OK button.
Click the “Now now” button to skip importing your browsing data from other browsers to Microsoft Edge.
Turn on or off the toggle switch for each option to confirm the privacy settings that best suit your needs.
Click the Accept button.
(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.
Click the Accept button to continue. Or click the Skip button to skip this part of the setup.
Click the “No, thanks” option from the bottom-left corner to skip linking your phone to your computer.
Click the “Not now” button to disable Cortana.

Once you complete the steps, the system will 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.

These are usually the same options available through the “Reset this PC” settings. However, you can also access the feature through WinRE (most commonly known as “Advanced startup”), 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, this option can only be used to reinstall the same operating system version already installed on the computer. If you also want to upgrade to the latest version, use the Media Creation Tool, ISO file, or USB options.

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

Start the device by pressing the power button.
Immediately after the Power-On Self-Test (POST), press the Power button again to shut down.
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.
Click the Advanced options button.
Click on Troubleshoot.
Click on the “Reset this PC” option.
Select the “Remove everything” option.
Click the Cloud download or Local reinstall option. The “Cloud download” option downloads a fresh image from the Microsoft servers and performs a fresh installation. The “Local reinstall” uses the locally available image to install a clean copy of Windows 10.
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 computer.)
Select the “Just remove my files” option to quickly delete the drive contents or the “Full clean the drive” option to delete everything using secure erase, which takes several hours. This option is suitable when preparing to give away the device.
Click the Reset button.
Click the Next button.
Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).
Click the Yes button.
Select your keyboard layout setting.
Click the Yes button.
Click the Skip button if you do not need to configure a second layout.
The computer will automatically connect to the network using an Ethernet connection. If you have a wireless connection, you must set up the connection manually.
Select the “Set up for personal use” option for Windows 10 Pro. (The “Home” edition does not have this option.)
Click the Next button.
Confirm your Microsoft account email to create an account.
Click the Next button.
Confirm your account password. (You can also use the Microsoft Authenticator app to sign in.)
Click the Next button.
Click the “Create a PIN” button.
Create a new PIN password.
Click the OK button.
Click the “Now now” button to skip importing your browsing data from other browsers to Microsoft Edge.
Turn on or off the toggle switch for each option to confirm the privacy settings that best suit your needs.
Click the Accept button.
(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.
Click the Accept button to continue. Or click the Skip button to skip this part of the setup.
Click the “No, thanks” option from the bottom-left corner to skip linking your phone to your computer.
Click the “Not now” button to disable Cortana.

Once you complete the steps, the process will reset your computer to the default settings by erasing and reinstalling a clean copy of Windows 10. The completion time will depend on your computer hardware configuration and selected reset configuration.

Clean install Windows 10 from ISO file

If you only have a Windows 10 ISO file, you can always mount the ISO in File Explorer to launch a clean install or in-place upgrade on a device with the operating system already installed.

To clean install Windows 10 from an ISO file, use these steps:

Download the Windows 10 ISO without using the Media Creation Tool.
Right-click the ISO file and select the Mount option.
Select the virtual drive from the left navigation pane.
Double-click the Setup.exe file to begin the Windows 10 installation.
(Optional) Click the “Change how Windows Setup downloads updates” option.
Select the “Not right now” option.
Click the Next button.
Click the Accept button to agree to the terms.
Click the “Change what to keep” option.
Select the Nothing option.
Click the Next button.
Click the Install button.
Click the Next button.
Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).
Click the Yes button.
Select your keyboard layout setting.
Click the Yes button.
Click the Skip button if you do not need to configure a second layout.
The computer will automatically connect to the network using an Ethernet connection. If you have a wireless connection, you must set up the connection manually.
Select the “Set up for personal use” option for Windows 10 Pro. (The “Home” edition does not have this option.)
Click the Next button.
Confirm your Microsoft account email to create an account.
Click the Next button.
Confirm your account password. (You can also use the Microsoft Authenticator app to sign in.)
Click the Next button.
Click the “Create a PIN” button.
Create a new PIN password.
Click the OK button.
Click the “Now now” button to skip importing your browsing data from other browsers to Microsoft Edge.
Turn on or off the toggle switch for each option to confirm the privacy settings that best suit your needs.
Click the Accept button.
(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.
Click the Accept button to continue. Or click the Skip button to skip this part of the setup.
Click the “No, thanks” option from the bottom-left corner to skip linking your phone to your computer.
Click the “Not now” button to disable Cortana.

Once you complete the steps, the clean installation process will begin, like using the Media Creation Tools or USB flash drive to upgrade the system.

Although you can still install the operating system on compatible devices, it’s important to remember that Microsoft plans to end the support of Windows 10 on October 14, 2025. After this date, devices will no longer receive maintenance and security updates. As a result, it’s also a good idea to consider performing a clean install on Windows 11 instead.

If the device doesn’t meet the hardware requirements, you can still proceed with the installation of Windows 11 on unsupported hardware with these steps.

Update August 2, 2024: This guide has been updated to ensure accuracy and reflect changes to the process.
