How to install Windows 11 without TPM 2.0

Here's how you can install Windows 11 without TPM 2.0. If you want to install it on your computer using either official or unofficial ISOs, you may be out of luck if your computer does not support Trusted Platform Module 2.0 or TPM 2.0. An attempt to install Windows 11 on a PC lacking TPM 2.0 will end up with the following error: "This PC can't run Windows 11. The PC must support TPM 2.0." Fortunately, it is easy to bypass the stumbling block. This article will show you how to install Windows 11 on a computer that does not support TPM 2.0.

Install Windows 11 Without TPM 2.0

Install Windows 11 from Windows Update without TPM 2.0

If you try to install a Windows 11 on a device without TPM 2.0 using the Settings app > Windows Update, it will end with a compatibility error. it will show youa requirement to enable TPM 2.0.


TPM Requirement For A Windows Update Released Build

To install Windows 11 downloaded from Windows Update, do the following.

  1. Open File Explorer and make sure it shows hidden files and folders.
  2. Go to the C:\$WINDOWS.~BT\Sources\Panther path.
  3. Open Windows Settings by pressing Win + I and go to Windows Update.
  4. Click the "Check for Updates" button and watch the "Panther" folder.
  5. Delete files appraiser.sdb and appreiserres.dll once they appear.Install Windows 11 Downloaded From Windows Update
  6. After that, Windows Update might show you an error. Dismiss it by clicking the "Retry" button.
  7. Install the latest Windows 11 build as usual.

This should allow to bypass the TPM 2.0 enforcement when receiving new builds via Windows Update.

Install Windows 11 Without TPM 2.0

You need Windows 11 installation ISO, a regular Windows 10 installation ISO, several commands in Command Prompt/PowerShell/Windows Terminal, and an ISO image editing tool like infamous UltraISO.

To install Windows 11 without TPM 2.0, do the following.

1)  Convert Windows 11 install.wim to install.esd

  1. Download Windows 11 installation ISO (it is up to you where to get it,) and double-click it in File Explorer to open its contents.
  2. Open its Sources folder, find the install.wim file and copy it to any preferred folder.Windows 11 Install.wim
  3. Now, launch Command Prompt, PowerShell, or Windows Terminal as Administrator.
  4. Enter the following command: dism /Get-WimInfo /WimFile:X:\Path\install.wim. Replace X:\Path with the path to the folder with the previously extracted install.wim file. For example, C:\Users\Taras\Desktop\install.wim.
  5. Next, find the index number for the SKU you want to install. For example, Windows Pro.Available SKUs In Install.wim
  6. Now, enter the following command: dism /export-image /SourceImageFile:"X:\Path\install.wim" /SourceIndex:INDEX /DestinationImageFile:"X:\Path\install.esd" /Compress:recovery /CheckIntegrity. Replace X:\Path with the path to your install.wim and INDEX with the index number for the desired SKU.Convert Install.wim To Install.esd
  7. Wait for Windows to complete converting wim to esd.
  8. Unmount (eject) Windows 11 ISO.

2) Replace install.esd in the official Windows 10 ISO

  1. Go to the official Windows 10 website and download Media Creation Tool. Use is to download Windows 10 ISO for your computer. Skip this step if you already have one.
  2. Open the downloaded Windows 10 ISO image in UltraISO.
  3. Delete the existing sources\install.esd file you see in UltraISO.
  4. Drag and drop the X:\Path\install.esd you have created onto the UltraISO window to place it instead of the deleted file.
  5. Click on Save or press Ctrl + S in UltraISO to alter the ISO image.

Now you have a fresh Windows 11 ISO file ready for installation on computers without TPM 2.0. Install it as a regular Windows 10.

Modify the ISO image without using UltraISO

If you don't have the UltraISO app, you can use Microsoft's official tool oscdimg, which is part of Windows ADK. Here's how you can use it to put the install.esd file with Windows 11 over the existing Windows 10 file in the ISO image.

  1. Double-click your Windows 10 ISO to mount and open it.
  2. Copy all files and folders to any preferable folder on your computer, say c:\ISOFOLDER.
  3. Copy your Windows 11 install.esd file you have created and paste it into the c:\ISOFOLDER\sources directory. Confirm the original file replacement.Replace Install.esd
  4. Open a command prompt and type oscdimg -m -o -u2 -udfver102 - bootdata:2#p0,e,bc:\ISOFOLDER\boot\,e,bc:\ISOFOLDER\efi\Microsoft\boot\efisys.bin c:\ISOFOLDER c:\ISOFOLDER\Windows11.iso.

Voila, you Windows11.iso is in the c:\ISOFOLDER ready for clean install!

Bypass the TPM 2.0 requirement without rebuilding install.esd

One of our readers sent me advice that instead of completely rebuilding the ISO image, it is enough to replace appraiserres.dll with the same file from Windows 10. For example, in this way.

  1. Open the Windows 11 image in UltraISO.
  2. Delete appraiserres.dll.
  3. Double click on the Windows 10 ISO file in Explorer to open its contents.
  4. Drag appraiserres.dll to the remote location in UltraISO.
  5. Save the Windows 11 ISO.


Replace appraiserres.dll in Windows 11 image with oscdimg

  1. Double click on the Windows 11 ISO file in File Explorer.
  2. Copy all content to c: \ ISOFOLDER folder.
  3. Double click on the Windows 10 ISO file in File Explorer.
  4. Take the appraiserres.dll file from Windows 10 and copy it with replacement to the c:\ISOFOLDER folder.
  5. Build the iso file with the command oscdimg -m -o -u2 -udfver102 - bootdata:2#p0,e,bc:\ISOFOLDER\boot\,e,bc:\ISOFOLDER\efi\Microsoft\boot\efisys.bin c:\ISOFOLDER c:\ISOFOLDER\Windows11.iso

Bypass the TPM 2.0 and Secure Boot requirements in the Setup program Registry

One more method is to disable the TPM and Secure Boot checks right before you install Windows 11, from its preinstallation environment.

As you may already know, modern Windows version load a minimal OS version, earlier known as "MiniOS", now know as Windows Preinstallation Environment. It loads the required set of drivers and starts the main Windows setup program.

You can modify its registry, so it won't perform TPM and SB checks. Here is how.

  1. Download and place this REG file to your bootable media with Windows 11, or on the hard drive.
  2. Boot your PC from that bootable media and set the language preferences.Windows 11 Setup Language Preferences
  3. On the next page, select Install now.Windows 11 Install Now In Setup
  4. On the product key page,  press Shift + F10 to open a command prompt window.
  5. Type notepad and hit Enter.Run Notepad From WinPE
  6. Select File > Open and specify  "*.* all files" for the file type option.WinPe Notepad All Files
  7. Browse for the REG file you downloaded (tpmbypass.reg), right-click it and select Merge.Bypass The TPM 2.0 And Secure Boot Requirements
  8. Voila, Windows 11 will be installed.

The contents of the REG file if you are curious.

Windows Registry Editor Version 5.00



After you successfully installed Windows 11, you may want to change your default browser, say to Chrome. This process is a bit tricky in the latest OS and can be confusing. We have a dedicated tutorial on how to change the default browser in Windows 11.

    Just replace from Windows 10 build appraiserres.dll Only

    1. Sergey Tkachenko

      Reportedly this causes Windows 11 to hang on “Getting devices ready”
      I was about to include this trick to the post, but changed my mind due to the issue.

      1. Andrei Rogachev

        Strange, everything works great for me.

        1. Sergey Tkachenko

          Let’s add this method to the post.

          1. GRAY78

            Doesn’t Work For Me So I am Trying Your Method

          2. peter

            Replace appraiserres.dll method is not working.

            After key in Windows Key and click Next, I got below message

            This PC can’t run Windows 11

            1st method is confirmed working.

          3. Sergey Tkachenko

            That’s great.
            That’s why I provided more that one solutions here.
            Thanks for your feedback Peter.

          4. EP

            replace appraiserres.dll method requires using an old W10 version of that file – use 17763.1 or older. 18362.1 & 19041.1 versions of appraiserres.dll may cause Win11 setup to crash

  2. aleJohnny

    Why needs to be so complicated?

    1. Just make a USB drive using Windows 10 ISO (English)
    2. Mount the Windows 11 ISO with Windows Explorer, and go to sources folder and copy install.wim.
    3. Paste the file in the USB drive, inside sources folder.

    Don’t need Secure boot, don’t need TPM.

    1. Sergey Tkachenko

      Well, this is for when you want a working ISO and not just a bootable USB stick.

    2. Shant

      Would you need to delete the Windows 10 install file? They are different extensions. Windows 11 is .wim and 10 was something else. Just want to confirm. Thank you for the comment!

    3. peter

      Tested your approach and confirmed it is working.

    4. mike

      I’m sure Windows 10 and Windows 11 are pretty much ALMOST SAME. They just made some changes to improve performance and graphics but in fact a machine running Windows 10 64bit shouldn’t have any problems on Windows 11 unless WANTED.

  3. Theo

    Hmm the latest windows 10 ISO I get from MS doesn’t have an .esd in it, though. It’s a .wim already. Replace .wim with a converted .esd?

    1. Sergey Tkachenko

      This should work as well.

  4. Cees Verburg

    Without knowing anything about TPM I installed Windows 11 without a problem using win2usb. Later I checked and I found our that TPM (my pc has version 1.2) was not even enabled.

    1. Wes

      TPM can be supported either throught the motherboard or CPU

  5. bowzee

    The appraiserres.dll method did not work for me, the installation aborts abruptly with no warning. After this, the Event Viewer shows an error related to appraiser.dll.

    The first method did work, so kudos to Taras. But, after the successful installation, many features do not show up because “your system does not meet the minimum requirements for Windows 11”, which could be interpreted as that at some point some update will break it for good.

  6. peter

    I have tested below notebook / tablet / PC and confirmed ‘hacked’ Win 11 can be installed.

    1. AllDoCube iWork 10 Pro – 4GB RAM, 64GB Storage (Atom x5-8350)
    2. Jumper EzPad Mini 8 – 2GB RAM, 64GB Storage (Atom x5-z8300)
    3. AL1 Mini PC – 4GB RAM, 512GB SSD (Celeron J3455)

  7. peter

    Testing status report on Jumper EzPad Mini 8 – 2GB RAM, 64GB Storage (Atom x5-z8300). I installed the same standard programs that I install on Windows 10.

    The Good:
    – Overall performance is better than Win 10 21H1. More responsive with such a low spec Windows Tablet.

    The Bad:
    – BatteryBar Pro can install however it does not show / display.
    – dotNet 3.5 cannot install initially but finally manage to install after google around and found the solution.

  8. Hoody

    If nothing else, maybe someone can put one of these ISO’s together and make it downloadable for people that don’t want to go through this.

    Right now my laptops will not work with 11, I do not have TMP on either one nor is it listed in any BIOS settings on either of them. My only other option is to get a new laptop with 11 installed or a used one in a year or so if a working method can’t be found other than this.

    I will attempt the reg solution though when I get hold of a valid W11 installer.

    Thanks for your app.

  9. Léo

    Thank you for sharing these methods, very useful!
    Just wonder, installing WIN 11 this way, will the OS receive the updates afterwards?
    Or the only way is to download and install the build each time?
    Thank you!

    1. Sergey Tkachenko

      Who knows? I think it won’t receive updates automatically, since it checks the hardware before installing the new build.

  10. caveman

    I tried replacing ‘install.wim’, but 60% thru install got message ‘couldn’t complete localization’.
    Next i tried the reg file method, i created a folder on the USB stick called ‘Registry’ and copied the reg file to there.
    But the ‘TPM’ message appeared directly after clicking ‘Install Now’ so i didn’t get to the product key page.

    So at the ‘Install Now’ page, before clicking ‘Install Now’ button, follow the rest of this method.
    It just means you are doing this one step earlier.
    Happy Hackin..

  11. Frank

    Hi everyone !
    Once intalled w11 if I go to windows update (Dev version), is asking again for the tpm module “to fix and update w11” , so we can get to w11 but … How can we update once we are in w11?
    Thanks for your help , and regards to everyone !

    1. Sergey Tkachenko

      I think that there is no way.
      You will have to do a clean install for each and every build.

      1. mike

        I’M SURE…. wait and the solution appear as a trick. 100% SURE.

  12. Ed

    What I don’t understand is.. why is Microsoft pushing out Windows 11, when Windows 8 to 10 have so many problems and errors? It is worse than previous versions..

  13. mike

    On my system only the reg file is not work. Error message appear “this pc is not etc…” If i change the DLL works perfectly. Thanks for this DLL TIP.

  14. mike

    in any case I HOPE they should leave the choice to the end user. Those who want to use Windows 11 with all the features will have to be equipped with TPM and UEFI otherwise the features of Windows 11 will be limited … I don’t see anything complicated. IF IT WERE NOT FOR THE FACT THAT NOW THEY WANT TO PROMOTE THE PURCHASE OF NEW HARDWARE.

  15. Daniel Thompson

    All I do is remove appraiserres.dll out of the sources folder and install Windows 11 with no problems.

  16. Peter Dugel

    Its not working i get this message, what do i do wrong??

    oscdimg -m -o -u2 -udfver102 – bootdata:2#p0,e,bc:\ISOFOLDER\boot\,e,bc:\ISOFOLDER\efi\Microsoft\boot\efisys.bin c:\ISOFOLDER c:\ISOFOLDER\windows11.iso
    ‘oscdimg’ is not recognized as an internal or external command,
    operable program or batch file.

    1. Sergey Tkachenko

      Simply oscdimg is missing.

      1. Peter Dugel

        So how do i get it in there and how can it be missing in Windows 10.
        Sence you write the guide to install it from a Windows 10 version right?
        How do i fix it?

        1. EP


          oscdimg is part of the Windows ADK kit and you have to download that from MS.
          it’s not built into the Win10 OS

  17. Manikandan

    The above steps are not working for Windows 11 22454.1000 Dev build

    1. Sergey Tkachenko

      which method you were using?

      1. Manikandan

        Tried all methods

  18. ard

    did not follow your rather complicated method, but
    I downloaded W11 ISO and installed it in Virtual Box.
    working fine
    this on an old notebook from 2012 with intel core 15-460M processor, it is running just on 2GB RAM because of low RAM on the notebook and though it runs slow, W11 does run.
