Important: Updated February 04, 2025

This support article was originally published on September 30, 2021, when Windows 11 was first released to the public. At the time of publication and still today, the intention behind this support page is to detail ways of installing Windows 11 on devices that meet system requirements for Windows 11. If you installed Windows 11 on a device not meeting Windows 11 system requirements, Microsoft recommends you roll back to Windows 10 immediately.

Windows 11 minimum system requirements remain unchanged and can be found in the article Windows 11 specs, features, and computer requirements.

Before installing Windows 11, make sure the device where Windows 11 is being installed meets the minimum system requirements. If the device is currently running Windows 10, Microsoft recommends verifying the minimum system requirements using the PC Health Check app. It isn't recommended to install Windows 11 on a device that doesn't meet requirements. For more information, see Installing Windows 11 on devices that don't meet minimum system requirements.

If upgrading from Windows 10 to Windows 11, Microsoft recommends waiting until Windows Update notifies that the upgrade is ready for the device. To check if Windows 11 is ready for a device using Windows Update, follow these steps:

  1. Right-click on the Start menu and then select Settings > Update & Security > Windows Update .
    Or
    Select the following Windows Update shortcut:
    Open Windows Update
  2. In the Windows Update window that opens, select the Check for updates button.
    Note: If there are updates available for the current version of Windows, the Windows 11 upgrade might not be made available until those updates are installed. Install any updates for the current version of Windows, restart the device, and then try checking for the Windows 11 upgrade again.
  3. If Windows 11 is ready to be installed on the device, a message is displayed in the Windows Update window showing that Windows 11 is ready. Select the Download and install button to start the Windows 11 upgrade.
  4. In the Software License Terms window that opens, select the Accept and install button.
  5. The Windows Update window refreshes and Status: shows the progress of the Windows 11 upgrade downloading and installing.
  6. Once the installation portion of the Windows 11 upgrade is done in Windows 10:
    • The Windows Update window refreshes and changes to Restart required. The Status: also updates to Pending restart.
    • A Windows Update notification is displayed in the notification area with the message Restart to install the newest Windows feature update.
      To continue the Windows 11 upgrade, restart the device by selecting the Restart now button in the Windows Update window or Restart now in the Windows Update notification.
  7. The device restarts and the Windows 11 upgrade process continues. The device restarts automatically a few more times to finish installing Windows 11.
  8. The Windows sign-on screen is displayed once the Windows 11 upgrade is done. Sign into the device to complete the upgrade.

Other methods to install Windows 11

The Windows 11 Installation Assistant is an app that provides assistance with upgrading to Windows 11. Microsoft recommends waiting until a device is offered the Windows 11 upgrade via Windows Update before using the Windows 11 Installation Assistant app. However, the Windows 11 Installation Assistance app can be used before Windows Update offers the Windows 11 upgrade.

When the Windows 11 Installation Assistant is run, one of the following options is displayed in the Windows 11 Installation Assistant window:

The Windows 11 installation media is an alternate method of installing Windows 11. Installation media is normally used to install Windows 11 on a device that doesn't already have Windows installed on it. However, it can also be used to upgrade existing installations of Windows to Windows 11.

For details on where to obtain the Windows 11 installation media and how to create it, see the article Create installation media for Windows.

Once the installation media is created, it can be used to upgrade an existing installation of Windows to Windows 11 using one of the following two methods:

Run the installation media in the current version of Windows

Windows 11 installation media can be used in the current version of Windows, for example Windows 10, to upgrade to Windows 11:

  1. Sign into Windows on the device being upgrade to Windows 11.
  2. Insert the Windows 11 installation media into the Windows device. For example, if the Windows 11 installation media was created on a USB flash drive, attach the USB flash drive to the Windows device.
  3. A pop-up notification window should appear asking what to do with the inserted media. Select Run setup.exe.
    If a pop-up notification doesn't appear:
    1. Right-click on the Start menu and then select File Explorer .
    2. When File Explorer opens, in the navigation bar, select This PC.
    3. In the results pane under Devices and drives, right-click on the Windows 11 installation media and select Install or run program from your media.
      Note: If the User Account Control window appears, select the Yes button. If the User Account Control window asks for an admin user name and password, enter a user name and password of an account that has administrator privileges. Once the user name and password are entered, select the Yes button.
  4. The Windows 11 Setup window opens. Step through the Windows 11 Setup pages, following instructions at each step.
  5. At the Ready to install page, the default is to Keep personal files and apps. However, selecting the Change what to keep link gives the following options:
    • Keep personal files and apps - Personal files, apps, and Windows settings are all kept and migrated to the new Windows 11 install. This option is the default option.
    • Keep personal files only - Personal files are kept and migrated to the new Windows 11 install, but apps and Windows settings are deleted.
    • Nothing - Everything is deleted, including personal files, apps, and Windows settings. If this option is selected and personal files are needed, they should first be backed up, for example to OneDrive or an external backup device.
      Select the desired option or accept the default of Keep personal files and apps. To start the upgrade, finish stepping through the Windows 11 Setup pages.
  6. The device is upgraded to Windows 11.

Boot from the installation media to install a fresh copy of Windows 11

Windows 11 installation media can be booted from on an existing Windows device to upgrade to Windows 11:

  2. Turn on the device that is being upgraded to Windows 11 and then initiate the device's boot menu. The boot menu is initiated by selecting an appropriate key on the keyboard when the device first boots. This key varies by device manufacturer and model but is usually one of the function keys (F1 - F12) at the top of the keyboard or the DEL key. For more information, see the device's documentation or the device manufacturer's website.
  3. From the device's boot menu, select the Windows 11 installation media.
