It’s been a few days since Windows 11 officially got released. Though, still many users are not able to upgrade 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.
Upgrade Windows 10 to Windows 11 Without USB Drive
Download Windows 11 ISO and Create Bootable USB Drive.
There are many ways to create Windows 11 Installation Media. You can either use Windows 11 media creation tool or Rufus. Moreover, if you don’t have USB Drive to upgrade to Windows 11. Then, you can simply mount Windows 11 ISO file using File Explorer. First, download Windows 11 stable ISO File, and, create a bootable USB Drive.
First, you need to replace a DLL file, after that, you can upgrade Windows 10 to Windows 11 on an unsupported PC without losing data.
Replace a DLL File.
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.
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 ads 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.
