Windows 10: Does an .iso file cotain all the software on my disk?

I've created an .iso file for Windows 11; I think it only contains the OS. How do I create an .iso file of all the files including downloaded software on my machine? Also, how big a DVD do I need to use?

wont boot into ISO file?

how the heck do you boot into an iso file?

did you burn this iso to a cd? or does this iso reside on your hdd. because if its on your hard drive, its not going to work. if you have nero or roxio, just burn the disk image to a cd. don't drag the iso file into the create data disk window, you actually have to select burn disk image.
