I’m not sure it will be that easy TSJnachos117… there are some checks performed. While I know you can cheat a standard CRC, it is not used anymore.
That said, I can see the day coming when someone actually manages to do what you suggest. With this move, Microsoft do let go of the control they had for updates and relying on integrity checks, may prove not to be enough in the long run.
If someone actually does it, it will be an even better arena than social media sites for spreading malware
