In this guide, you will find instructions about upgrading to Windows 11.

Preparation

Before you start the upgrade, make sure that the following points are met:

• Make sure that backup is turned on.
  Make sure to back up your important files before upgrading. You can do this, for example, using OneDrive or another backup service (check Microsoft OneDrive).
• Before starting the installation, make sure you have saved any work in progress.
• Make sure that your computer has enough free disk space to install Windows 11.
  At least 32 GB of free space is recommended (check How to free up space on my computer?).
• If you are using a laptop, make sure that the charger is connected during the installation.
  This will help prevent unexpected shutdowns and ensure a smooth installation process.
• If updates are available for your current version of Windows, the Windows 11 upgrade may not be available until you install these updates.
  Install the updates for your current version of Windows, restart your device, and then try to search for the Windows 11 upgrade again.
• We recommend starting this process at the end of the workday, as you will not be able to use your computer for other activities at the same time.
  Your computer will automatically restart several times during the installation. The process can take 30 minutes to 2 hours.

Installing

1. Once the Windows 11 upgrade has been tested and validated for a specific computer, Windows Update will show that it is ready to install:

   1. Open Start → click Get updates → click Check for updates.
      1. If clicking Check for updates doesn't offer an update, try clicking Check online for updates.
