It’s been a few days since Windows 11 officially got released. Though, still many users are not able to upgrade from Windows 10 to Windows 11. Because of unsupported CPU and TPM. If the PC health check app or Windows 11 setup is showing you “This PC doesn’t meet Windows 11 system requirements” or “This PC can’t run Windows 11“. Then no worries, still you can install Windows 11 on an unsupported PC/Laptop.
But before start following this article to install Windows 11, first, check if TPM support is available on your PC/laptop or not. Because, if TPM is supported by your system, then by enabling it you can install Windows 11. Though, if your processor isn’t currently supported for Windows 11, then here’s how, you can install it. Alternatively, you can install rectify11 on an old laptop. It is a modified version of Windows 11, that works without TPM and Secure Boot.
Upgrade Windows 10 to Windows 11 Without TPM/Secure Boot
There are many ways to install Windows 11 on an unsupported Windows 10 Laptop. You can either use Rufus to bypass the security check. Or, you can replace a DLL File to bypass. In this article, you will find all methods.
Method 1: Use Rufus to bypass TPM and Secure Boot
Rufus is the oldest free and open-source portable app to create bootable USB Drives. If you have a Windows 11 ISO file, then undoubtedly Rufus will help you to create a bootable USB. And thankfully, now Rufus provide two image option when you select Windows 11 ISO File.
Standard Windows 11 Installation (TPM 2.0 + Secure Boot)
Extended Windows 11 Installation (no TPM / no Secure Boot)
So, while creating a bootable USB drive through Rufus, you just have to select the “Extended Windows 11 Installation” option. And, that’s it, it will just bypass TPM and Secure Boot check during Windows 11 installation.
Note: If you choose the Extended option, then do make sure the secure boot is disabled. Else, you will face some errors during installation.
First, insert your USB Drive into Computer to create a bootable drive. Just do make sure there isn’t any important data in it.
Now, Run Rufus Tool as Administrator.
Click on Select, and do select downloaded Windows 11 ISO File.
After that in the image option, do select “Extended Windows 11 Installation (no TPM / no Secure Boot)”.
Now, select your partition scheme.
How to check your disk partition scheme?.
Open “disk management” by right-clicking on the start (Windows Icon in the taskbar) button.
Right-Click on your disk and then click on properties.
Click on the Volumes tab, and you can see your partition style now.
After selecting partition style in Rufus, type “Windows 11” in the volume label.
Click on start. A warning might appear, that all data will get deleted from the USB drive. Click on ok to confirm.
That’s it, now wait till the ready status in Rufus turned into green completely.
Once, the bootable USB Drive gets created. You can either boot from it and perform a clean Windows 11 installation.
Or, you can just open Bootable USB Drive from File Explorer and can run the “Setup” file as administrator. Windows 11 setup window will appear, and that will help you to upgrade Windows 10 to Windows 11.
Method 2: Replace a DLL File (Upgrade to Windows 11 Without USB)
Windows 11 setup comes with a DLL file that checks for CPU and TPM support. We have modified that file to skip TPM and CPU check. So that, you can upgrade your Windows 10 laptop or PC. You just have to replace that file, and after that, you can run Windows 11 setup.
Download appraiserres Zip file from the below link.
Once the zip file gets downloaded, right-click on it and then click on Extract All > Extract.
Open Extracted Folder and then copy “appraiserres.dll” file.
Do open File Explorer. Right-Click on the Bootable USB Drive that you have created and click on Open.
Open Sources Folder, and Right-Click anywhere, and then click on Paste. (appraiserres.dll file exists in the source folder, so we’re going to replace it.)
A popup window will appear, click on the “Replace the file in the destination” option.
Run Windows 11 Setup and Install.
That’s it, now you can install Windows 11. Open bootable USB Drive and Run Setup File. (Right-Click on Setup File and then click on “Run as Administrator”.)
Wait for a few seconds and Windows 11 setup window will appear. Click on next.
License terms window will now appear, click on accept.
Windows 11 setup will now check for updates. And, a ready to install window will appear. That will show you Windows 11 version as per your current Windows 10 version.
e.g. – I was using Windows 10 home, so I can only update to Windows 11 Home.
That’s it, Installing Windows 11 window will appear. Your PC will restart a couple of times during the installation process, so keep connected to power. And, don’t interrupt the process. The process might also be taking time because you’re upgrading not doing a clean installation. (Also, if you’re using HDD instead of SSD, then also process will take longer.)
Once Windows 11 gets installed. Press Windows + R key, type winver, and press enter. That’s the way you can check Windows 11 version.
Ok, so that’s how you can upgrade Windows 10 to Windows 11 on an Unsupported PC Without TPM. If you face any issues during the installation process let me know in the comment section.
