How to Change Windows 10 to 11 on a Laptop

What You’ll Need

A laptop that meets Windows 11 minimum requirements (see Step 1).
At least 64 GB of free storage space (more is better for updates).
An internet connection (broadband or mobile hotspot).
Your Microsoft account credentials if you use one.
An external backup drive or cloud storage for your files.
For the USB method: a USB flash drive with at least 8 GB capacity (all data on it will be erased).

Step-by-Step

Check compatibility – Download and run Microsoft’s PC Health Check app from the official Microsoft website. It will tell you if your laptop meets Windows 11’s requirements: a compatible 64-bit processor, 4 GB RAM, 64 GB storage, UEFI secure boot, and TPM 2.0. If it says “not compatible,” you cannot upgrade without workarounds that are not recommended.
Back up your data – Copy important files to an external drive or cloud storage (like OneDrive, Google Drive, or Dropbox). Also note your installed apps and product keys if you have them. This protects you if the upgrade fails or causes problems.
Update Windows 10 fully – Go to Settings > Update & Security > Windows Update and install all pending updates. Restart your laptop if prompted. A fully updated Windows 10 makes the upgrade smoother.
Free up disk space – Ensure you have at least 64 GB free on your main drive (C:). If not, use Disk Cleanup (search “Disk Cleanup” in Start) to remove temporary files, or uninstall large apps you no longer need.
Open Windows Update – Go to Settings > Update & Security > Windows Update. Click “Check for updates.” If Windows 11 is available for your device, you’ll see a banner saying “Upgrade to Windows 11 is ready.” Click “Download and install.”
Follow the on-screen prompts – The download may take a while. Once downloaded, you’ll be asked to accept the license terms and choose whether to keep your files and apps. Select “Keep personal files and apps” (the default) to preserve everything.
Restart and wait – The installation will restart your laptop several times. Do not turn it off or unplug it during this process. It can take 30–90 minutes depending on your hardware. Your laptop will boot into Windows 11 when done.
Verify and set up – After the first boot, sign in with your Microsoft account (or create a local account). Check that your files, apps, and settings are intact. Go to Settings > System > About to confirm you’re on Windows 11.

Common Mistakes

Ignoring compatibility – Installing Windows 11 on unsupported hardware can lead to instability, missing driver updates, and no security patches. Always run PC Health Check first.
Skipping the backup – Even though the upgrade usually keeps your files, a power outage or driver issue can cause data loss. Always back up.
Not updating Windows 10 – If your Windows 10 is out of date, the upgrade may fail or be blocked. Install all pending updates first.
Forcing the upgrade via USB on unsupported hardware – This is possible but not recommended; you may end up with a laptop that won’t receive updates or has driver problems.
Turning off the laptop during installation – This can corrupt the system. Let it finish even if it seems stuck on a black screen for a while.
Not checking storage space – If your drive is nearly full, the upgrade will fail. Free up space before starting.

Tips

Use the Installation Assistant – If Windows Update doesn’t offer the upgrade, download the Windows 11 Installation Assistant from Microsoft’s official site. It walks you through the same process and is more reliable than manual methods.
Keep your laptop plugged in – Use AC power during the entire upgrade to avoid battery drain causing a shutdown mid-installation.
Close unnecessary apps – Before starting, close all programs, especially antivirus software (temporarily) and any tools that modify system files. This reduces conflicts.
Note your drivers – After upgrading, visit your laptop manufacturer’s support site to download the latest Windows 11 drivers for your model (especially chipset, graphics, and Wi-Fi).
Wait a few days after release – If you’re not in a hurry, wait a couple of weeks after a major Windows 11 update to let Microsoft fix initial bugs. This is not essential but can save headaches.

Troubleshooting

Windows Update doesn’t show Windows 11 – Run PC Health Check again to confirm compatibility. If compatible, wait 24–48 hours; Microsoft rolls out the upgrade in waves. Alternatively, use the Installation Assistant.
Upgrade fails with error code – Note the error code (e.g., 0x80070070). Common fixes: free up disk space, disable third-party antivirus temporarily, run Windows Update troubleshooter (Settings > Update & Security > Troubleshoot), and try again.
Laptop is stuck on a black screen – Wait at least 30 minutes. If it doesn’t progress, force a restart by holding the power button for 10 seconds. If it boots to Windows 10, the upgrade failed; check for error messages and try again.
Apps or drivers don’t work after upgrade – Reinstall the affected apps. For drivers, go to Device Manager (right-click Start) and check for yellow exclamation marks. Right-click the device and select “Update driver.” If that fails, download drivers from your laptop manufacturer’s website.
You want to go back to Windows 10 – Within 10 days of upgrading, you can roll back: Settings > System > Recovery > “Go back” (or “Previous version of Windows”). This keeps your files but removes Windows 11. After 10 days, the option disappears, so decide quickly.

Frequently Asked Questions

Is the upgrade to Windows 11 free?

Yes, if your laptop meets the requirements, the upgrade from Windows 10 to Windows 11 is free through Windows Update.

Will I lose my files and apps during the upgrade?

No, if you choose “Keep personal files and apps” during installation. However, it’s always safest to back up first.

My laptop is from 2017. Can I install Windows 11?

It depends on the specific hardware. Run PC Health Check. Many older laptops lack TPM 2.0 or a compatible CPU, so they won’t be officially supported.

How long does the upgrade take?

Typically 30–90 minutes, depending on your internet speed and laptop performance. The download itself can take a while, and the installation involves several restarts.

Can I upgrade without a Microsoft account?

Yes, you can use a local account during setup, but some features (like OneDrive sync) require a Microsoft account. You can create a local account after installation.

What if I don’t like Windows 11 after upgrading?

You have 10 days to roll back to Windows 10 via Settings > System > Recovery. After that, you’ll need to do a clean install of Windows 10, which requires a backup.
