Change the CPU to 64 bit via CMD, is that possible?
If a CPU is 32 bit and you believe that you can change it to 64 bit, for example change 64 bit via CMD, that is of course not possible not only on Windows 11, 10, ... etc.!
The 64-bit processor, regardless of whether it is from Intel or AMD, cannot become 64-bit by command; this is the processor architecture that cannot be changed by software. However, you can install a 32-bit operating system on an x64 processor.
