WHAT OPERATING SYSTEM AM i REALLY USING/RUNNING?

When l look at Settings>Updates>Check for updates: I am usually presented with an update such as the one just now: Security Intelligence Update for Microsoft Defender Antivirus - k32267602 (version 1.443.4.0) current channel (broad) completed00 - After checking for updates I will then go to SETTINGS> IT clearly shows that I am running Windows 11 PRO. CAN SOMEONE PLEASE TELL ME WHY IN PLACES THAT ARE TRACKING ME AND TAKING MY PERSONAL INFORMATI0N, THAT IT SH0WS OR SAYS THAT I am running Windows 10? I often see it if I sign into one of the many different accounts that require 2 factor authentication, which will send me a notification alerting me that someone has signed into my account from a NEW DEVICE. OR FROM AN UNKNOWN DEVICE. That is when they ask if I recognize this login and it shows device and location from which the login attempt is happening. IF I answered honestly, (because it is showing a login attempt happening from a (WINDOWS 10 SYSTEM) and my system shows Me that it is running Windows 11 PR0: it would flag as suspicious and my account would get locked up for sure. Instead, because of the odd hour of the night it occurs, that combined with the location I know it is myself and even though it says "ON A SYSTEM RUNNING WIND0WS 10", I force myself to lie and answer that I do recognize the attempt. PLEASE SOMEONE HELP FIND A SOLUTI0N TO THIS ERROR. THANK YOU IN ADVANCE
