Is Windows optimized on PCs?

If you e.g. Latops Restarts and an update is installed, it often says "Do not switch off the PC.", Even though it is a laptop

A laptop that is not from Apple is a PC. The design is just smaller than that of a tower or desktop model. So app users may be irritated when they see this message on their windows installation in the boot camp. But they should be able to think so far that they know what is meant.

PC stands for personal computer. Your laptop is also a computer. The only difference is the construction of the individual components.

Is Windows optimized on PCs?

Not directly. Due to the very different hardware, there's no way to optimize the operating system for everything. This works more in a separate ecosystem like MAC or consoles.

If you e.g. Latops Restarts and an update is installed, it often says "Do not switch off the PC.", Even though it is a laptop

And this is easy to explain.
A laptop is also a PC, because what you see as a "PC" is really a "Desktop PC", or Tower PC. Quite simply, PC only stands for personal computers. And this term also includes a laptop.

An Apple device is also a PC because it remains a personal computer.

Is optimized for both, and now also for tablets (virtual keyboard or tablet mode) … A small battery appears in the taskbar, but it is always (more or less) the same Windows…

Apple prohibits extensive changes to the hardware, there's nothing "personal".

A laptop is a PC, it has nothing to do with whether you can fold it up or not. Apart from the physical design and the performance, there's hardly any difference between desktop PCs and laptops. Both mostly use x86 processors, DDR RAM, and so on. From there, there's nothing that you would have to optimize differently, apart from things like battery optimization, but obviously there are in Windows.

It just has nothing to do with it:
