1. Check If Your PC Meets Windows 11 Requirements

Before upgrading, make sure your computer meets the minimum system requirements for Windows 11. Microsoft has specific hardware requirements, including TPM 2.0, Secure Boot, a compatible 64-bit processor, and sufficient memory and storage.

Even if your PC runs Windows 10 without problems, it does not automatically mean it can upgrade to Windows 11. Checking compatibility first can save time and help you avoid starting an upgrade that your hardware does not support.

How to Check Windows 11 Compatibility

  • Open Settings > Windows Update.
  • Check whether Windows 11 offers an upgrade notification.
  • Use Microsoft’s PC Health Check app for a detailed compatibility report.

The tool will check your processor, TPM version, Secure Boot status, memory, and storage to confirm whether your device is ready for Windows 11.

You can also verify the following requirements manually:

  • A compatible 64-bit processor
  • 4 GB RAM or more
  • 64 GB or more available storage
  • TPM 2.0 enabled
  • Secure Boot enabled
  • A graphics card compatible with DirectX 12 and a supported display

Quick Tip: If your PC is not compatible because TPM 2.0 or Secure Boot is disabled, check your BIOS/UEFI settings before assuming your hardware cannot run Windows 11.

2. Back Up Your Important Files

Backing up your important files is one of the most important steps before installing Windows 11. Although the upgrade is designed to keep your files, apps, and settings, unexpected problems can occur during any major operating system upgrade.

Make sure your important documents, photos, videos, work files, and other personal data are stored safely before starting the upgrade. You can use an external hard drive, USB storage device, or a cloud backup service such as OneDrive.

Backup your data

What you should back up

  • Documents, spreadsheets, and work files.
  • Photos and personal videos.
  • Important downloads and project folders.
  • Browser bookmarks and saved passwords.
  • Any files stored on the desktop.

Quick Tip: Do not rely only on files stored on your PC. Keep at least one additional copy of important data in another location so you can restore it if something goes wrong during or after the upgrade.

3. Free Up Enough Storage Space

Windows 11 needs enough free storage space to download installation files, create temporary files, and complete the upgrade successfully. If your drive is nearly full, the installation may fail or not start at all. This is especially common on older laptops with smaller SSDs or devices that have accumulated years of temporary files.

How to Free Up Storage Space

  • Open Settings > System > Storage to see what is using your disk space.
  • Remove unnecessary temporary files using Storage Sense or Disk Cleanup.
  • Uninstall apps you no longer use.
  • Move large files, such as videos and backups, to external storage or cloud storage.

Quick Tip: Try to keep at least 30 GB or more of free space available before starting a Windows 11 upgrade. Having extra space gives Windows enough room to complete the installation smoothly.

4. Install Pending Windows Updates

Installing the latest Windows 10 updates before upgrading can improve compatibility and fix known issues that might prevent the Windows 11 upgrade from installing successfully. It also ensures your PC has the latest security updates and service improvements before you move to Windows 11.

How to Check for Windows Updates

  1. Open Settings using Windows + I.
  2. Go to Update and security, then Windows Update.
  3. Click Check for updates.
  4. Download and install any available updates.
  5. Restart your PC if required.

Quick Tip: After installing updates, restart your computer and check Windows Update again to ensure there are no pending updates before starting the Windows 11 upgrade.

5. Update Your Device Drivers

Keeping your device drivers up to date helps ensure your hardware works properly with Windows 11. Outdated drivers can sometimes cause compatibility issues, installation errors, or hardware problems after the upgrade, especially for graphics, network, and storage devices.

How to Update Drivers Before Upgrading

  • Open Settings > Windows Update > Advanced options > Optional updates and install available driver updates.
  • Check your PC manufacturer’s support website for the latest drivers.
  • Update important drivers such as graphics, network, chipset, and audio drivers.

Quick Tip: Avoid using third-party driver updater tools before upgrading. Windows Update and your PC manufacturer’s official website are safer sources for getting compatible drivers.

6. Check Your Apps and Software Compatibility

Most modern applications work without issues on Windows 11, but it’s worth checking the software you rely on before upgrading. Older programs, security software, or business applications may require updates to ensure full compatibility with the latest Windows release.

Checking your apps beforehand helps you avoid surprises after the upgrade, especially if you depend on specific programs for work, school, or daily tasks.

Things to Check Before Upgrading

  • Update important apps to their latest versions.
  • Check whether your work or productivity software supports Windows 11.
  • Temporarily disable or uninstall third-party antivirus software if it has previously caused update or installation issues.
  • Note any apps you may need to reinstall after the upgrade.

Quick Tip: Most modern apps work without changes on Windows 11. However, if you’ve experienced update problems in the past, temporarily disabling or uninstalling third-party antivirus software before upgrading can help avoid compatibility issues. Be sure to re-enable or reinstall it after the installation is complete.

7. Disconnect Unnecessary Peripherals

External devices and their drivers can occasionally interfere with major Windows upgrades. Disconnecting unnecessary peripherals before installing Windows 11 helps reduce the chance of hardware-related installation issues.

Devices to Disconnect Before Upgrading

  • USB flash drives and external hard drives.
  • Printers, scanners, and webcams.
  • Memory card readers and docking stations.
  • External audio devices and other unnecessary USB accessories.

Leave only your keyboard, mouse, monitor, and internet connection (if needed) connected during the upgrade. Once Windows 11 is installed successfully, reconnect your devices one at a time.

Quick Tip: If you’re upgrading a laptop, disconnect unnecessary USB devices but keep the power adapter connected throughout the installation.

8. Ensure a Stable Power and Internet Connection

The Windows 11 installation can take some time to complete, so it’s important to have a reliable power source and internet connection before you begin. Interruptions during the download or installation may delay the upgrade or require Windows to restart the process.

Before You Start the Upgrade

  • Plug your laptop into AC power.
  • Use a stable Wi-Fi or wired Ethernet connection.
  • Avoid downloading large files while the upgrade is in progress.
  • Do not shut down or restart your PC unless Windows asks you to.

Quick Tip: If possible, start the upgrade when you won’t need to use your computer for a while, so the installation can finish without interruption.

9. Start the Windows 11 Upgrade

Once you’ve completed the preparation steps above, you’re ready to install the latest version of Windows 11. If your PC meets the system requirements, you can upgrade directly through Windows Update. If the update isn’t available yet, you can use Microsoft’s Installation Assistant.

How to Upgrade to Windows 11

  • Open Settings and go to Windows Update.
  • Click Check for updates.
  • If the Windows 11 upgrade is available, select Download and install.
  • Follow the on-screen instructions to complete the installation.
  • Restart your PC when prompted.

How much free space do I need to upgrade to Windows 11?

Microsoft recommends at least 64 GB of available storage to install Windows 11. However, keeping 30 GB or more of additional free space is a good idea to allow Windows to download installation files, create temporary files, and complete the upgrade without running into storage-related issues.

Will I lose my files when upgrading to Windows 11?

No. If you upgrade through Windows Update or the official Windows 11 Installation Assistant, your personal files, installed apps, and most settings are kept by default. Even so, it’s always recommended to back up important files before upgrading in case something goes wrong during the installation.

Can I upgrade to Windows 11 for free?

Yes. If your PC is running a genuine, activated copy of Windows 10 and meets the Windows 11 system requirements, you can upgrade to Windows 11 at no additional cost using Windows Update or Microsoft’s official installation tools.

What if my PC doesn’t meet the Windows 11 requirements?

If your computer doesn’t meet the minimum hardware requirements, Windows Update won’t normally offer the upgrade. You can continue using Windows 10 until its support ends or consider upgrading your hardware or purchasing a Windows 11-compatible PC. While unofficial installation methods exist, Microsoft doesn’t recommend them because they may lead to compatibility, security, or future update issues.

How long does it take to upgrade to Windows 11?

The upgrade time depends on your PC’s hardware, internet speed, and the size of the update. On most modern computers, the process typically takes 30 minutes to an hour, while older devices may take longer.
