The data required by the operating system (passwords, access controls, accounting information, and so on) would have to be stored in or passed through unprotected memory and thus be accessible to unauthorized users.

What generation computers were the first to use operating systems containing instructions that any software could use?
I'm not sure what you are asking. Third generation computers were the first to have fully functional OSs supplied by the manufacturer. They were also the first to come with supervisor/user modes where some instructions could only be executed by the OS in Supervisor mode, user programs would error out if they executed such instructions directly. This protected the OS and I/O devices from defective user code. To perform any I/O or interact with other programs the user programs had to call OS service routines to coordinate the actions and execute the required Supervisor only instructions.

What allows the computer to start?
When a computer is powered on, the CPU loads BIOS into memory, and then, based on the BIOS boot configuration, loads physical sector 1 from that boot device to a specific memory location, and then jumps to that memory location to begin executing the master boot loader code. Drive geometry is determined, and then the master boot record entries determine where each partition's logical boot sector is located on the device. It finds the active partition, reads that partition's boot sector code into memory, and then jumps to that location. Once it does that, it follows the instructions in that boot loader code to switch to Protected Mode, allocate necessary memory, load the operating system into memory, sets up descriptor tables, and then jumps to that location. At that point, the operating system is actually executing...and the rest of the system loads.

It's also possible to get bulk licenses for multiple machines, such as at a business or school, and most licenses (embodied in the End User Licensing Agreements) do specify that it is legal to make a backup copy as well.
