A:Answer Hello there. Thank you for your question. This Lenovo - ThinkPad L450 laptop system comes with a 5th Generation Intel® Core™ i5-5300U Processor, which is not listed under the Windows 11 Supported Processors list provided by Microsoft, (see https://docs.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-intel-processors) however, to check if this laptop is compatible with this operating system, we suggest checking directly with the system manufacturer using the link below:
