It’s exciting when a new version of Windows comes out, isn’t it? Windows 11 brings a fresh look, snappier performance, and some important security upgrades that can really make your computer feel new again. But for many of us, that excitement quickly turned into a headache.

Microsoft set some pretty strict rules for Windows 11 compatibility, especially around the main processor (CPU) and a security chip called TPM 2.0. This left a lot of perfectly good Windows 10 computers out in the cold, telling us they just weren’t ready for Windows 11.

But here’s a secret: “not ready” doesn’t always mean “never.” With Windows 10 reaching its official end-of-life for regular security updates on October 14, 2025, getting to Windows 11 is becoming more than just a nice idea—it’s about keeping your computer safe and running smoothly. The good news? The clever folks in the tech world have found ways around these rules.

This guide will show you two simple, free Windows 11 upgrade methods to get Windows 11 on unsupported hardware. We’ll walk through each step so you can unlock all the new features, better security, and a smoother experience on your existing machine, even if it originally failed the Windows 11 requirements check. Think of it as giving your current PC a new lease on life without spending a dime on new parts!

1.   Getting Started: Why Your PC Might Say No to Windows 11

When Windows 11 first arrived, many of us eagerly ran the compatibility checker, only to be met with a disappointing message. It felt like our computers, which had been perfectly fine just moments before, were suddenly too old.

1.1.   The Hurdles: What Windows 11 Looks For

The main sticking points for Windows 11 installation usually boil down to two things:

• Your Computer’s Brain (CPU): Microsoft wants a fairly modern If your computer’s CPU isn’t on their approved list (generally Intel 8th generation or newer, or AMD Ryzen 2000 series or newer), the official Windows 11 upgrade process stops right there.
• The Security Chip (TPM 0): This is a small but mighty security feature that helps protect your computer. Many older computers either don’t have TPM 2.0 at all, or it might be turned off in your computer’s settings (BIOS/UEFI). This is a common reason for an “incompatible” message.

When you try to upgrade Windows 10 to Windows 11 through the usual routes, like Windows Update, “Your PC might say, ‘This PC can’t run Windows 11.’ And Microsoft has made it clear— they’re not budging on the official requirements.” This becomes a bigger deal when you consider that Windows 10 compatibility for free security updates ends soon. After October 2025, staying on Windows 10 means risking your computer’s security, unless you’re willing to pay for extended updates – which most home users aren’t.

1.2.   The Workarounds: There’s Always a Way

Even with Microsoft’s firm stance, the tech community has found clever solutions. These tricks don’t magically change your computer’s parts, but they allow the Windows 11 installation to proceed by making it skip those strict checks. Think of it like a secret handshake that gets you past the bouncer.

Over time, Microsoft has tried to make these workarounds a bit harder, but dedicated enthusiasts keep finding new ways. While these methods are very successful for most computers that originally ran Windows 10, extremely old machines, especially those with very outdated AMD processors, might still hit some snags with the absolute newest versions of Windows 11.

For this guide, we’re assuming you have a genuine version of Windows 10 (Home or Pro) and you’re logged in as an administrator. Our goal is to show you how to do an in-place upgrade, meaning your existing files, programs, and settings stay right where they are. No need to start from scratch!

2.   Picking Your Path: Which Upgrade Method is Right for You?

Before we dive into the step-by-step instructions, let’s figure out which of the two methods makes the most sense for your computer. It really depends on what your PC is missing.

2.1.   Method 1: The Registry Tweak (For PCs Almost There)

This method is often the simplest if your computer meets most of the Windows 11 requirements, particularly if it uses modern startup settings (UEFI) and has a TPM chip, even an older one (like TPM 1.2), or if your TPM 2.0 is just switched off.

• Modern Startup (UEFI): Your computer needs to start using something called UEFI, which is the newer way computers power If your PC is using “Legacy BIOS” (an older method), you’d need to do some more complicated steps, like converting your hard drive’s setup (from MBR to GPT). This can be tricky and might be better avoided if you’re not comfortable with it.
• Secure Boot: Your computer should support Secure Boot in its You don’t necessarily have to turn it on for this method to work, but it’s a good idea for better security on Windows 11.
• TPM Chip Present (Any Version): You must have a TPM chip that’s turned Even if it’s an older TPM 1.2, this method can work. Most computers that came with Windows 10 should have TPM 2.0. If your PC simply doesn’t have a TPM chip at all, or if you can’t turn it on in your computer’s settings, then this method won’t be for you.

How to Check Your PC’s Settings (Before You Start!):

1. Check Startup Mode: Type Msinfo32.exe into the Windows search bar and press Enter. Look for “BIOS Mode” on the “System Summary” If it says “Legacy,” you might want to consider Method 2 instead.
2. Check TPM Status: Type msc into the Windows search bar and press Enter. This will open the “Trusted Platform Module Management” tool. If it shows information about a TPM chip, you’re good. Look for the “Specification Version” – ideally 2.0, but 1.2 is fine for this method. If you see a message like “Compatible TPM cannot be found,” then your PC either doesn’t have one or it’s disabled.

2.2.   Method 2: The Rufus Tool (For PCs That Need More Help)

The Rufus tool is your best friend if your computer is older and simply doesn’t have a TPM chip, doesn’t support Secure Boot, or if changing your BIOS from Legacy to UEFI seems too complicated. Rufus helps create a special Windows 11 media creation tool on a USB drive that automatically skips those difficult checks. It’s like having a magic key for your Windows 11 installation guide.

2.3.   A Note About Newer Windows 11 Versions (Like 24H2)

Microsoft keeps updating Windows 11, and with the recent version 24H2, they’ve added another hurdle: your computer’s processor needs to support specific instructions called SSE4.2 and PopCnt. Most Intel chips from 2009 or later and AMD chips from 2013 or later already have these.

But if your PC was built in 2008 or earlier, it simply won’t have these instructions, and neither of these methods will let you install Windows 11 version 24H2 or later. Starting with 24H2, Microsoft requires processors to support SSE4.2 and PopCnt—two instruction sets not available on CPUs from before 2009 (Intel) or 2013 (AMD).

2.4.   What About a Clean Installation?

This guide focuses on an upgrade from Windows 10 to Windows 11 process that keeps your files and programs. A clean install wipes your drive and starts fresh—it can skip many checks, but you’ll need to back up everything first since it erases all files and apps.

3.  Method 1: The Simple Registry Tweak

This method involves making a small, but powerful, change in your computer’s registry. It’s a great way to bypass the CPU checks and allow older TPM versions. Remember, for this to work, you’ll need to start the Windows 11 upgrade process from within your current Windows 10 system, not by booting from a USB drive.

Important Warning: The Windows Registry is like the control center of your computer. Making wrong changes can cause big problems. While this specific tweak is safe and widely used, it’s always smart to back up your important files or create a system restore point before you begin. Just in case!

3.2.   Step-by-Step Guide:

Follow these four steps carefully to ensure a smooth Windows 11 installation:

• Making a Small Change in the Windows Registry

This little trick tells the Windows 11 installation program to ignore the specific CPU checks and also to accept older TPM versions (like 1.2). Fun fact: Microsoft actually used to tell people about this trick on their own support website, though they’ve since removed those instructions.

1. Open the Registry Editor: Press the Windows Key and R on your keyboard at the same In the small box that pops up, type regedit and hit Enter. If a window asks for permission, click “Yes.”
2. Find the Right Spot: In the Registry Editor window, you’ll see a tree-like structure on the Carefully navigate to this location: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
3. Create the ‘MoSetup’ Folder (if it’s not there): If you don’t see MoSetup listed under Setup, you need to create Right-click on the Setup folder on the left, choose New > Key, and type MoSetup. Press Enter.
4. Create the New Setting: Now, click on the MoSetup folder (the one you just created or found). In the big empty space on the right side of the window, right-click and choose New > DWORD (32-bit) Be careful not to pick QWORD!
5. Name the Setting: A new item will appear. Carefully type its name exactly as AllowUpgradesWithUnsupportedTPMOrCPU and then press Make sure there are no typos!
6. Give it a Value: Double-click on the AllowUpgradesWithUnsupportedTPMOrCPU setting you just In the small window that appears, change the number in the “Value data” box from 0 to 1.
7. Save and Restart: Click OK to save your Close the Registry Editor. It’s super important to restart your computer right away for this change to take effect.

3.2.2.  Getting the Windows 11 Installation File (ISO)

Now that your computer is ready to bypass those pesky checks, you need to download the actual Windows 11 ISO file. This is the main Windows 11 installation guide package.

1. Go to Microsoft’s Download Page: On the computer you’re upgrading, open your internet browser and go to the official Windows 11 media creation tool download page: ms/DownloadWindows11.
2. Find the ISO Download: Scroll down the page until you see the section that says “Download Windows 11 Disk Image (ISO) for x64 “
3. Pick Your Language: Use the dropdown menu to choose your preferred A quick tip for English (UK) users: Some people have found that if you select “English International,” the upgrade might not let you keep your installed programs and files. To make sure you have the option for a full Windows 10 to Windows 11 upgrade (keeping everything), it’s a good idea to pick “English (United States),” even if it’s not your usual choice. You can always change your regional settings after the Windows 11 upgrade.
4. Download the File: Click “Confirm,” then click “Download.” This file is quite large (usually 5-6 gigabytes), so it might take a while depending on your internet Save it to a place you can easily find, like your “Downloads” folder.

3.2.3.  Opening the ISO File Like a DVD

Once the download is done, you need to “mount” the Windows 11 ISO file. This simply means your Windows 10 computer will treat it like a physical DVD that’s been put into a drive, allowing you to access its contents.

1. Find the ISO: Open File Explorer (you can press Windows Key + E on your keyboard). Go to the folder where you saved the Windows 11 ISO
2. Mount It: Double-click the Windows 11 ISO Windows 10 has a built-in feature that does this automatically, creating a virtual drive (like D: or E:) just for that file.

3.2.4.  Starting the Windows 11 Upgrade

With the ISO now “open,” you can begin the Windows 11 upgrade process.

1. Go to the Virtual Drive: In File Explorer, click on the new virtual drive that appeared (it will have the Windows 11 icon).
2. Run Setup: Inside that virtual drive, find the file named exe and double-click it. This starts the actual Windows 11 installation.
3. Don’t Worry About Warnings: A warning might pop up about unsupported hardware— just click ‘Accept’ and keep You can safely click “Accept” to continue. Even though it sounds scary, Microsoft has continued to provide security updates for Windows 11 installations on officially unsupported hardware. The main point of this warning is that you might not get feature updates directly through Windows Update, but security is still covered.
4. Finish the Upgrade: After you click “Accept,” the Windows 11 upgrade should move forward without any major If you’re upgrading from the same version (e.g., Windows 10 Home to Windows 11 Home),

you’ll usually get three choices:

• Keep personal files and apps: This is the recommended “Full Upgrade” It keeps all your documents, programs, and settings.
• Keep personal files only: This will save your documents, but give you a fresh start with programs and
• Nothing: This wipes everything and performs a clean install Windows 11. Choose what you prefer and follow the on-screen instructions. Your computer will restart several times during this Windows 11 upgrade

4.   Method 2: Using the Free Rufus Utility

This method is a lifesaver for those computers that just can’t meet the TPM or Secure Boot requirements, or if your PC is stuck in that older Legacy BIOS mode. Rufus is a fantastic, free program that helps you create a special USB drive for Windows 11 installation that automatically skips many of those tough compatibility checks. It’s truly a useful Windows 11 upgrade tool for Windows 11 unsupported hardware.

While you could try to manually trick the installer by messing with internal files, Rufus makes everything much easier and less prone to errors.

Important Things to Note:

• Rufus Version: Make sure you download the very latest version of Rufus, specifically version 6 or newer. Older versions might not work because Microsoft made some changes to its compatibility checks around late 2024.
• Older CPU Limitations: Even Rufus can’t perform miracles for extremely old If your processor dates back to 2008 or earlier, it likely won’t have the necessary SSE4.2 and PopCnt instructions required for Windows 11 version 24H2.
• USB Drive Needed: You’ll need an empty USB flash drive that’s at least 16 GB in size. Rufus will erase everything on this drive, so make sure you back up any important files from it first! Don’t save your Windows 11 ISO file on this USB drive before starting with Rufus, as it will be wiped
• Step-by-Step Guide:

Follow these steps to create your special Windows 11 installation USB drive and then start the Windows 11 upgrade:

• Getting Rufus and the Windows 11 File
  1. Download Rufus: Head over to the official Rufus website: ie. Download the latest version (you might see a “Portable” version, which means you don’t even have to install it).
  2. Download Windows 11 ISO: On the computer you’re planning to upgrade incompatible PC to Windows 11, go to Microsoft’s official Windows 11 media creation tool download page: ms/DownloadWindows11. Download the Windows 11 ISO file and save it to your computer’s main storage, like your Downloads folder (not your USB drive yet!).

4.3.2.  Creating Your Special Windows 11 USB Drive

1. Plug in Your USB Drive: Insert your empty (or backed-up) USB flash drive into your
2. Run Rufus: Double-click the Rufus program you Click “Yes” if it asks for permission.
3. Choose Your USB: In Rufus, make sure your USB drive is selected in the “Device” dropdown It’s very important to pick the right one here so you don’t accidentally erase the wrong drive!
4. Select the Windows 11 ISO: Under “Boot selection,” click the “SELECT” Find the Windows 11 ISO file you downloaded earlier and choose it.
5. Start the Process: After choosing the ISO, click the “START”
6. The “Windows User Experience” Box: A special window will pop This is where you tell Rufus to bypass the checks. Make sure to select the first checkbox: “Remove requirement for 4GB+ RAM, Secure Boot and TPM 2.0.” You can also choose other options here, like removing the need for a Microsoft account during setup or turning off privacy questions, but the first one is key for bypassing those Windows 11 system requirements.
7. Confirm and Create: Click “OK.” Rufus will warn you that everything on the USB drive will be Click “OK” again to confirm. The process will take a little while.
8. Ready! Once Rufus shows “READY” in its status bar, your special Windows 11 installation USB drive is complete. You can close Rufus.

4.3.3.  Starting the Windows 11 Upgrade

Just like with the registry method, you don’t boot from this USB drive to perform an in-place upgrade. You run the setup program from within your Windows 10 system.

1. Open the USB Drive: Open File Explorer and navigate to your newly created bootable USB
2. Run Setup: Find the exe file on the USB drive and double-click it. This begins the upgrade Windows 10 to Windows 11 process.
3. Ignore Warnings (Again!): You’ll probably see that familiar warning about Windows 11 Again, it’s just a scare tactic. Click “Accept” and proceed. Your PC will still receive security updates. This method helps install Windows 11 without TPM or Windows 11 upgrade without Secure Boot headaches.
4. Complete the Upgrade: After accepting, your Windows 11 upgrade process should continue You’ll be given choices about keeping your files and apps, keeping only files, or a clean install Windows 11. Pick the option you prefer and follow the remaining steps. Your computer will restart a few times as it updates to Windows 11.

6.  Frequently Asked Questions (FAQs)

Q1: Will my computer still receive security updates after installing Windows 11 on unsupported hardware?

A1: Yes, based on current observations, Microsoft has continued to provide security updates for Windows 11 on unsupported hardware installations. However, there’s no formal guarantee this will continue. The warnings you see during installation mostly refer to the lack of feature updates through standard Windows Update channels. Critical security patches have still been arriving so far—but that could change in future Windows 11 releases.

Q2: Is it safe to use these methods? Will they damage my computer?

A2: These methods involve modifying system settings or using a third-party tool (Rufus) to create installation media. While they are widely used and generally considered safe, any process involving system changes carries a small inherent risk. That’s why we strongly recommend backing up your important files before you begin. Following the steps carefully, as outlined in this Windows 11 installation guide, minimizes any risk.

Q3: Can I go back to Windows 10 if I don’t like Windows 11?

A3: Usually, yes. After a Windows 10 to Windows 11 upgrade, Windows typically saves your previous Windows 10 installation files for about 10 days. This allows you to roll back to Windows 10 if you decide Windows 11 isn’t for you. However, if you perform a clean install Windows 11, you won’t have this option, and going back would require reinstalling Windows 10 from scratch.

Q4: Will my programs and files still work after the upgrade?

A4: If you choose the “Keep personal files and apps” option during the Windows 11 upgrade process, nearly all your existing programs, documents, and settings should transfer over smoothly. Very old or specialized software might have compatibility issues with Windows 11, but this is rare for most common applications.

Q5: What are the main benefits of upgrading to Windows 11 if my PC is “incompatible” with the official Windows 11 requirements?

A5: Even on older hardware, Windows 11 offers a refreshed look, a more modern user interface, performance improvements (especially in areas like gaming and multitasking), and enhanced security features compared to Windows 10. Plus, you’ll stay supported with security updates beyond Windows 10’s end-of-life, making it a valuable free Windows 11 upgrade.

Q6: I’m stuck on a step or have an error message. What should I do?

A6: Don’t worry! These processes can sometimes have unexpected hiccups.

You might still have a few questions bouncing around in your head — and that’s totally normal.

Things like:

• Can my PC actually run Windows 11? My computer’s a bit older, and I’m not sure if it meets Microsoft’s requirements, like TPM 0 or Secure Boot. How do I check, and what can I do if it doesn’t?
• What are the risks of forcing the upgrade? If I bypass Microsoft’s restrictions to install Windows 11, could it mess up my system, slow it down, or cause other issues?
• Will my apps and files be safe? I’ve got important programs and data on my Will upgrading to Windows 11 wipe anything or make my software incompatible?
• How can I upgrade if my PC isn’t supported? Are there workarounds to get Windows 11 on my machine, like tweaking settings or using specific tools? How complicated is it?
• Is it worth upgrading at all? My PC’s been fine with Windows Are Windows 11’s features—like the new interface or performance improvements—worth the hassle for an older system?
• What happens when Windows 10 support ends? I’ve heard Windows 10 support stops in October If I stick with it, will my PC be vulnerable or unusable?
• Can I go back if I don’t like it? If I upgrade to Windows 11 and it doesn’t work out, can I easily revert to Windows 10 without losing my stuff?
