However, if you still want to install Windows 11 on a
device that does not meet these requirements, you can
bypass the check for TPM 2.0 and the CPU family and
model. Keep in mind that installing Windows 11 on
ineligible hardware carries the risk of encountering
compatibility issues and your device may no longer be
supported or entitled to receive updates. Damages to
your device due to lack of compatibility may not be
covered under the manufacturer warranty.
If you are unsure if your device meets the minimum
requirements for Windows 11 and you have Windows 10
installed, you can use the PC Health Check app to assess
your eligibility and identify any components that do not
meet the requirements. The app will also provide
information on how you can make your device meet the
minimum requirements. If you experience issues after
upgrading to Windows 11 and your device does not meet
the minimum requirements, you can go back to Windows 10
within 10 days of the upgrade. After this time, the
files needed for this process will be removed to free up
disk space on your device.
