    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.

    Please identify what type of disk system you purchased with your 2019 iMac. If it is a Fusion drive, and you used Bootcamp, then it installed Windows on a partition created on the slow hard disk part of the Fusion drive. If you installed it on a SSD, then you may have a problem here ....

    It is a fusion drive, on the HD. But should that really mean that it takes 3-4 mins to boot? And loading basic things like settings or edge can take up to 30 seconds. Even loading websites is really slow, compared to macOS. I’m actually getting better performance on my 2015 MacBook Air than I am in windows on this new iMac. I used windows 10 on work computers which had HD drives, and the performance was better even though those computers had worse specs. Admittedly, it has been so long since I have used windows for personal use that I’m not quite sure what kind of performance I should even expect. But I feel like Vista on a 2009 laptop performed better or equally to this.

    Did you install the Bootcamp Support drivers? Because if you didn't, without GPU drivers the system can run very slow.

    Ok, I can confirm that something was wrong, because most of the symptoms are gone now. It boots much more quickly, and it doesn’t take 5 minutes for the task bar to full load after the desktop has loaded. No new updates, so I really don’t know what was going on. One problem does persist however: windows does not immediately recognise the magic keyboard and track pad. Once the desktop has fully loaded, then I can use them.
