I actually just did a clean win10 install on my Dell XPS 9530, and using the 2013 rapid start software, got it working without any noticeable issues. The latest BIOS for my XPS was just released post Win10 release, and it still contains the option to enable rapid start, but I am still not sure if there is any benefit to having IRST and why it has not been updated.
Posted a more direct questing on this both on Intel and Dell forums, but so far nobody has any clear information on this.
Would really be helpful to know if IRST with worth enabling on Win10, if not I can recover 16GB of space on the dedicated IRST partition.
