[Quick Tip] How to Install Windows 11 on Unsupported CPU


Windows 11 is free, and Microsoft has put a hefty price tag on it by giving it a long list of hardware requirements. If your computer fails to comply with those requirements, Windows 11 simply refuses to get installed. Below is a screenshot taken from my Lenovo laptop, showing the processor isn't currently supported for Windows 11 and unable to install Windows 11 on this device.

PC Health Check Unsupported CPU

 

The good news is that there is a catch to fix it. This means even the computer has an unsupported CPU, there is a workaround to help you bypass CPU check and install Windows 11 successfully on unsupported hardware. Read more if you want to know the details.

CPU Requirement for Windows 11

To upgrade to Windows 11 from Windows 10, your PC has to meet a list of requirements. Some of the most notable ones are:

  • Minimum 1 GHz of dual-core CPU.
  • 4 GB of RAM.
  • 64 GB of free space.
  • TPM 2.0 chip.
  • UEFI compatible motherboard.
  • Secure Boot

However, these are the minimum requirements. To be honest, its not easy to meet most of these requirements if you have an old computer, especially for supported CPU, which should be Intel Core 8th-Gen or later, AMD Ryzen 3 2rd-Gen or later. The full supported list of CPU can be found in here (Intel and AMD).

However, many online users reported that they had installed Windows 11 on computers which do not support some or any of these requirements, and yet, Windows 11 runs fine on their system! So, even if your computer has an unsupported CPU, it is still possible to install Windows 11 on it and take it for a ride.

It has been seen that even if your computer has an Intel i5 (3rd, 4th, or 5th gen), or an Intel i7 (6th, or 7th gen) CPU, your computer will still be able to install Windows 11 on those unsupported CPUs even if they are not on the official compatibility list.

To run Windows 11 on a computer with unsupported CPU, the first thing you need to do is to create Windows 11 installation media. For that, you need 3 things: Windows 11 ISO image file, a blank USB flash drive and a utility to make bootable USB from Windows 11 ISO image file.
