Read the fine FUD, only updates have the Microsoft draconian requirements -- Full installs from USB likely run just fine. Note however, these full Win 11 23h2 installs on older machines will not get the offers to upgrade to any later versions. They will pick up any activations existing on the machines. e.g. applying a USB 23h2 upgrade to a W11 Pro which was upgrade from Win11 Home with a Win 7 pro key, the install ran just fine and the result was an activated Win 11 pro 23h2. This full Win install to the existing Win partition did not even mess up a dual boot with Ubuntu,. Following the pattern of EOLing of Win 11 21h2 in two years, you will need one of these full installs every two years, if Microsoft still allows them. I guess Microsoft could stop updates at any time, but why would they, they even update unactivated copies.
