Notes: Intel's Arc graphics driver for this processor supports Windows 10 (21H2) and Windows 11, while the Intel NPU driver is available for Windows 11 only. Microsoft lists Core Ultra (Series 1) on the Windows 11 24H2 and 25H2 processor lists; 26H2's list is not yet published, so the 25H2 status is carried over. Linux runs from kernel 6.7 onward; the NPU uses the intel_vpu driver.
