Windows 11 comes preinstalled on new computers or as a free upgrade from Windows 10

If your computer runs Windows 10, you can move to Windows 11 at no cost through Windows Update. If you are buying a new machine, Windows 11 comes already installed. If you have an older computer running Windows 7, 8, or 8.1, you will need to purchase a Windows 11 license — the cost varies by retailer but typically ranges from $120 to $200 for a standard copy. The path you take depends on what you have now and whether your hardware meets Windows 11's requirements.

Before you start, check whether your computer can run Windows 11. Microsoft requires a processor from Intel's 8th generation or newer, or AMD Ryzen 2000 series or newer. You also need at least 4 GB of RAM, 64 GB of storage space, and a system firmware that supports UEFI (most computers built after 2015 have this). A free tool called PC Health Check, available from Microsoft's website, will tell you whether your machine qualifies.

Key Takeaways

  • Windows 10 users can move to Windows 11 for free by opening Settings, selecting Update & Security, and running Windows Update.
  • Your computer must have a compatible processor (Intel 8th gen or newer, or AMD Ryzen 2000 or newer) and UEFI firmware to run Windows 11.
  • New computers typically ship with Windows 11 already installed, so you do not need to install it yourself.
  • If you own an older computer running Windows 7, 8, or 8.1, you will need to buy a Windows 11 license from a retailer like Amazon, Best Buy, or Microsoft directly.
  • The upgrade process from Windows 10 takes 20 to 30 minutes and preserves your files, settings, and installed programs.

Upgrading from Windows 10 for free

Open the Start menu and type "Settings" into the search box, then click Settings. In the Settings window, select "System" on the left side, then scroll down and click "About." Look for a button labeled "Check for updates" or navigate to "Update & Security" instead. Windows will check whether your computer qualifies and whether the upgrade is ready for your device.

If Windows 11 is ready, you will see an option to read and install it. Click that option and let the read complete — this can take 30 minutes to an hour depending on your internet speed. Once the read finishes, Windows will ask you to restart your computer. Save your work first, then restart. The installation happens automatically after the restart and typically takes 20 to 30 minutes. Your files, programs, and settings will remain in place after the upgrade finishes.

If Windows says your computer does not meet the requirements, the upgrade is not available to you through this method. In that case, you would need to either stay on Windows 10 (which Microsoft still supports) or replace the computer with one that meets Windows 11's hardware standards.

Buying Windows 11 for older computers

If your computer runs Windows 7, 8, or 8.1, you cannot upgrade for free. You will need to purchase a Windows 11 license. Retailers like Amazon, Best Buy, Newegg, and the Microsoft Store all sell Windows 11 Home and Windows 11 Pro editions. Home is the standard version for personal use; Pro adds features like remote desktop and encryption that most home users do not need. Prices vary slightly by retailer, but expect to pay around $120 to $140 for Home and $200 for Pro.

When you buy Windows 11, you receive a product key — a 25-character code that you enter during installation. Some retailers send this key by email; others print it on the box. Keep this key in a safe place. You will also need to read the Windows 11 installation media from Microsoft's website using another computer, then transfer it to a USB flash drive (at least 8 GB). The installation process wipes your hard drive, so back up your files before you begin.

Insert the USB drive into your computer, restart it, and boot from the USB (you may need to press a key like F12 or Delete during startup to access the boot menu). Follow the on-screen prompts, enter your product key when asked, and choose the drive where you want to install Windows. The installation takes 15 to 20 minutes. After it finishes, you will have a fresh copy of Windows 11, and you can reinstall your programs and restore your backed-up files.

Windows 11 on new computers

Most computers sold today come with Windows 11 already installed and ready to use. When you turn on a new computer for the first time, it will walk you through setup — choosing your language, connecting to Wi-Fi, and signing in with a Microsoft account. You do not need to install anything yourself. The license is tied to your computer's hardware, so you cannot transfer it to another machine.

If you buy a computer from a major retailer like Best Buy, Dell, HP, or Lenovo, Windows 11 is included in the price. Some budget computers or refurbished machines may come with Windows 10 instead, so check the product listing before you buy if Windows 11 is important to you.

Using the Media Creation Tool for a clean install

If you want to perform a fresh installation of Windows 11 on a computer that already has Windows 10, you can use Microsoft's Media Creation Tool instead of waiting for Windows Update. This method erases everything on your drive and installs a clean copy of Windows 11, which some people prefer because it removes old files and clutter that accumulate over time.

read the Media Creation Tool from Microsoft's website on another computer. Run it, select "Create installation media for another PC," and follow the prompts to create a bootable USB drive. Insert the USB into your computer, restart, and boot from the USB. Follow the installation steps, choose to erase your drive when prompted, and let Windows 11 install. This process takes about 20 minutes. Afterward, you will have a clean Windows 11 system, but you will need to reinstall your programs and restore your files from backup.

Checking your hardware before you start

Windows 11 has stricter hardware requirements than Windows 10, and not every older computer can run it. The most common reason for incompatibility is the processor. If your computer is more than 8 to 10 years old, it likely has a processor that Windows 11 does not support. You can check your processor by opening Settings, selecting "System," then "About," and looking for the processor name under "Device specifications."

Another common issue is UEFI firmware. Older computers use BIOS instead, and Windows 11 requires UEFI. You can check this in the same About screen — look for "System firmware" and see whether it says UEFI or BIOS. If it says BIOS, you cannot upgrade to Windows 11 without replacing the motherboard, which is usually not worth the cost. In that case, staying on Windows 10 is the practical choice.

Microsoft's PC Health Check tool automates this process. read it from Microsoft's website, run it, and it will tell you exactly what your computer has and whether it meets Windows 11's requirements. If it does not, the tool will explain which component is the problem.

What to do if your computer does not may have access to

If your computer does not meet Windows 11's requirements, you have three options. First, you can stay on Windows 10. Microsoft will continue to support Windows 10 until October 2025, so it remains find and functional for several more years. Second, you can upgrade your hardware — replacing the processor and motherboard is expensive and often not practical for older computers. Third, you can buy a new computer that comes with Windows 11 already installed.

If you choose to stay on Windows 10, keep Windows Update turned on so you receive security patches. Windows 10 will not automatically upgrade to Windows 11 if your hardware does not may have access to, so you do not need to worry about an unwanted change.

Frequently Asked Questions

Can I upgrade from Windows 10 to Windows 11 without losing my files?

Yes. The free upgrade from Windows 10 preserves all your files, programs, and settings. The process takes 20 to 30 minutes and happens automatically after you restart. If you use the Media Creation Tool for a clean install instead, that erases everything, so you would need to back up your files first.

Do I need a product key to upgrade from Windows 10?

No. The upgrade is free and does not require a product key. Windows will recognize that your computer is licensed for Windows 10 and automatically license Windows 11 on the same hardware. If you are buying Windows 11 for an older computer, you will need a product key.

How long does the Windows 11 upgrade take?

The read takes 30 minutes to an hour depending on your internet speed. The installation after restart takes 20 to 30 minutes. During this time, your computer will restart several times automatically. Do not turn off your computer during the process.

Can I downgrade from Windows 11 back to Windows 10?

Yes, but only within 10 days of the upgrade. After that, you would need to perform a clean install of Windows 10 using installation media, which erases everything. If you think you might want to go back, back up your files before you upgrade.

What is the difference between Windows 11 Home and Pro?

Home is for personal use and includes all the features most people need. Pro adds remote desktop, encryption, and the ability to join a domain, which are mainly useful for business environments. For home use, Home is sufficient and costs less.
