Stuck at downloading Windows Support Software

I have been trying to install Windows 10 via Boot Camp Assistant but it's so bugged. It crashed one time and caused my Mac to reboot when it was almost done downloading the Windows support software and then it kept getting stuck there while using all my download speed on my following attempts.

My previous experience was Boot Camp was bad anyways because any issues while installing Windows 10 will have me to redownload the support software all over again which takes forever on my internet. Is there a way to manually download the support software so I can reuse it if something comes up? I tried Boot Camp > Action > Download Windows Support Software but Boot Camp will never detect it so it's pretty much useless.
