In late 2021, Microsoft began rolling out Windows 11 to Windows 10 users. Your Lumedica OCT system came pre-installed with an Intel NUC running Windows 10 Pro. We are actively working to determine compatibility of Windows 11 with our Lumedica OCT systems. At this time, please decline any prompts to upgrade to Windows 11 until we have completed our testing. Microsoft continues to release security updates to Windows 10, and we recommend accepting these updates.
