Final answer:
A Windows process must contain at least one thread to execute, which serves as the smallest unit of execution within a process.
Step-by-step explanation:
A Windows process must contain at least one thread to execute. In Windows operating systems, a process is the environment that the operating system provides for a program to execute, while a thread is the smallest unit of execution within a process.
Each process starts with a single primary thread, but can create additional threads. A thread has the necessary execution context, including instruction pointer, stack, and a set of processor registers, which allows it to execute program code.
A Windows process must contain at least one thread to execute. A thread is the smallest unit of execution within a process, and it represents an independent sequence of instructions that can be scheduled to run by the operating system.
While a process can have multiple threads, even a single-threaded process contains at least one thread to perform its tasks.
