Check Whether Your Computer Can Run Windows 11

Before you start the update process, your computer must meet Windows 11's hardware requirements. Microsoft provides a free tool called the PC Health Check app that scans your system and tells you whether it can run Windows 11. read it from Microsoft's website, run it, and it will show you which requirements your computer meets and which it does not.

The main requirements are a processor from Intel (8th generation or newer) or AMD (Ryzen 2000 series or newer), at least 4 GB of RAM, 64 GB of storage space, and a display that supports 9 inches or larger at 720p resolution. Your computer also needs TPM 2.0 (a security chip), which most computers made after 2016 have built in. If the PC Health Check app says your computer cannot run Windows 11, the update will not work, and you should not attempt it.

Write down any incompatibilities the app reports. Some older computers can still update if you change settings in your BIOS (the system firmware), but this requires technical knowledge. If you are unsure, contact the computer manufacturer's support line before proceeding.

Key Takeaways

  • Run the free PC Health Check app from Microsoft to confirm your computer meets Windows 11 requirements before you start.
  • Back up all your files to an external drive or cloud storage before beginning the update, because data loss during updates is rare but possible.
  • The update process takes 20 to 60 minutes depending on your internet speed and how much data is on your computer.
  • Windows 11 will install over your existing Windows 10 system and keep your files, programs, and settings in place.
  • If the update fails or causes problems, Windows 10 remains on your computer and you can roll back within 10 days.

Back Up Your Files Before You Start

Updating your operating system carries a small risk of data loss or system problems. Before you do anything else, back up your important files. The safest method is to copy your Documents, Pictures, Desktop, and Downloads folders to an external hard drive or USB drive. Plug the external drive into your computer, open File Explorer, and drag these folders to the external drive. This takes 10 to 30 minutes depending on how much data you have.

If you do not have an external drive, you can use cloud storage instead. Services like OneDrive (which comes with Windows), Google Drive, or Dropbox let you upload files from your computer. Sign into the service on your computer, upload your important folders, and the files will be stored online. This method is slower than using a physical drive but works if you have a stable internet connection.

Do not skip this step. If something goes wrong during the update, you will have your files safe on another device.

read Windows 11 Using the Update Assistant

Microsoft's Windows 11 Installation Assistant is the simplest way to update. Go to Microsoft's Windows 11 read page, find the "Installation Assistant" option, and click the read button. The file is about 500 MB and will read in a few minutes on a typical internet connection.

Once the read finishes, open the Installation Assistant file (it will be named something like "Windows11InstallationAssistant.exe"). Click "Accept and Install" when prompted. The tool will check your system again and then read the full Windows 11 files to your computer. This read is about 4 to 5 GB and may take 15 to 45 minutes depending on your internet speed. Do not close the window or turn off your computer while this is happening.

If your internet connection is slow or unstable, the read may pause or fail. If this happens, close the Installation Assistant and try again later when your connection is stronger. You can also use a wired ethernet connection instead of Wi-Fi, which is usually faster and more reliable.

Run the Installation and Restart Your Computer

After the Installation Assistant finishes downloading Windows 11, it will prompt you to restart your computer. Save any open work, close all programs, and click "Restart Now." Your computer will shut down and restart automatically.

During the restart, Windows 11 will install itself. You will see a black screen with a spinning circle or progress bar. This phase takes 10 to 30 minutes. Your computer may restart several times during this process — this is normal. Do not turn off your computer or unplug it during installation. If the power goes out, the update may fail and your system could become unstable.

Once installation finishes, your computer will boot into Windows 11. You may see a setup screen asking you to sign in with your Microsoft account or local account. Use the same account you used on Windows 10 so your files and settings transfer over.

Verify the Update and Reinstall Drivers if Needed

After Windows 11 finishes installing and you log in, check that the update was successful. Right-click the Start button (the Windows logo in the bottom left), select "Settings," then go to "System" and scroll down to "About." You should see "Windows 11" listed under "Edition." If you see Windows 10, the update did not complete and you should restart your computer.

Windows 11 usually installs drivers (software that lets your hardware work) automatically, but occasionally a device like your printer, graphics card, or network adapter may not work properly. If something is not working, go to the device manufacturer's website, read the latest driver for Windows 11, and install it. For example, if your printer is not printing, visit the printer manufacturer's support page, search for your printer model, and read the Windows 11 driver.

Check that your internet connection, display, sound, and any external devices (printers, scanners, external drives) are working. If something is broken, restart your computer first — many driver issues resolve after a restart. If a device still does not work after restart, contact the manufacturer's support line with the device model number.

Roll Back to Windows 10 if the Update Causes Problems

If Windows 11 causes serious problems — your computer crashes, programs do not work, or hardware fails — you can go back to Windows 10 within 10 days of the update. After 10 days, this option disappears permanently.

To roll back, right-click the Start button, go to "Settings," then "System," then "Recovery." Click "Go Back" under "Recovery Options." Your computer will restart and return to Windows 10, keeping your files intact. This process takes 15 to 45 minutes. After you roll back, you can try the update again later, contact Microsoft support, or stay on Windows 10.

If more than 10 days have passed and you want to go back to Windows 10, you will need to perform a clean install, which erases everything on your computer. This is a more complex process and requires a Windows 10 installation disk or USB drive. Contact Microsoft support or a local computer repair shop if you need help with this.

Frequently Asked Questions

Do I need to uninstall Windows 10 before installing Windows 11?

No. The Installation Assistant updates Windows 10 to Windows 11 in place. Your files, programs, and settings stay on your computer. You do not need to uninstall anything or erase your hard drive.

Will my programs and files still be there after the update?

Yes. Windows 11 keeps your files, documents, and most programs. Some very old programs written for Windows 7 or earlier may not work, but anything you use on Windows 10 should work on Windows 11. If a program stops working, contact the software maker to see if they have a Windows 11 version.

How long does the whole update take?

The total time depends on your internet speed and computer. Downloading Windows 11 takes 15 to 45 minutes. The installation itself takes 10 to 30 minutes. Plan for 1 to 2 hours total from start to finish, and do not use your computer for other tasks during this time.

What if the update fails halfway through?

If the Installation Assistant crashes or the read fails, close it and try again. If the installation fails after restart, your computer will usually boot back into Windows 10. Run the Installation Assistant again. If it fails multiple times, restart your computer, wait a few hours, and try once more. If it keeps failing, contact Microsoft support or a local computer repair shop.

Can I update over Wi-Fi or do I need a wired connection?

Wi-Fi works, but a wired ethernet connection is more reliable for large downloads. If your Wi-Fi is slow or drops frequently, plug an ethernet cable into your computer and router before starting the update. This reduces the chance of the read failing partway through.
