This assistant is for those who wish to upgrade a Windows 10 PC to Windows 11.

Before you begin, check to see if the following conditions apply to you:

  • You have a Windows 10 license.
  • Your PC must have Windows 10, version 2004 or higher installed to run Installation Assistant.
  • Your PC meets the Windows 11 device specifications for upgrade requirements and supported features. Certain features require additional hardware. We also recommend that you visit your PC's manufacturer's website for information about updated drivers and hardware compatibility.
  • Your PC must have 9 GB of free disk space to download Windows 11.

After you download the Installation Assistant:

  • Select Run. You need to be an administrator to run this tool.
  • Once the tool confirms the device hardware is compatible, you will be presented with the license terms. Select Accept and Install.
  • Once the tool is ready, click the Restart Now button to complete installation on your computer.
  • It might take some time to install Windows 11, and your PC will restart a few times. Make sure you don't turn off your PC.

If you need installation media to install Windows 11 on a different PC or an Arm64 device, see Create Windows 11 Installation Media.

Is the Windows 11 Installation Assistant an official application from Microsoft?

Yes, it's an official tool from Microsoft designed to help you upgrade a Windows 10 PC to Windows 11 without creating bootable media. Simply download and run the tool, then follow the steps to upgrade while keeping your files and apps intact.

How do I know if my PC is compatible with Windows 11?

The tool itself will check for basic compatibility-like having Windows 10 version 2004 or later and sufficient free space (around 9 GB). For a deeper check (e.g., TPM, secure boot), it prompts you to use the PC Health Check app, and after running it, simply click Refresh in the Assistant window to get updated compatibility feedback.

Will the tool keep my personal files and apps?

Yes, by default, the Installation Assistant performs an in-place upgrade, installing Windows 11 while preserving your files, apps, and most settings. You'll get an option before install that lets you confirm what to keep.

How long does the upgrade take, and what happens during the process?

Typically between 30 minutes to an hour, depending on your internet speed and hardware. The tool downloads Windows 11, prompts for a restart, and undertakes installation with multiple reboots. Make sure your PC is plugged in and turned on throughout.
