I have installed windows on my new 2019 iMac using bootcamp. There were no problems with the installation as far as I can tell, except that windows is extremely slow. I am trying to figure out whether to blame Microsoft or if there is something I can or need to do to fix this. It takes a few minutes for windows to boot up, even after enabling "fast boot". Then opening any app the first time takes several seconds at least, sometimes up to a minute. Is there anything I can do to fix this? I have gone through several articles about how to sped up windows 10, but none of that has helped.
