Why restart CPU is a must after slot in PCIe card (SV dev kit) during run time

I'm using Altera Stratix V devkit configure as PCIe Gen3 speed. I have couple of silly questions regarding the interfacing... 1.) First of all, I will use external power supply for the devkit...

Any one interested in writing an application to allow FPGA configuration without reboot? That can be a big time saver. I found this hint on the hooks available in Windows world. http://stackoverflow.com/questions/22203316/reset-fpga-based-pcie-card-and-restore-its-config-space

There should be no need to create a hack. The "correct" way is to force re-enumeration of the PCI/PCIe buses. This works under Linux already. The question is how to do this under Windows. It is possible, since I can plug and unplug my ExpressCard (which is PCIe) and I think it gets detected "plug-and-play" style ... but that could be poor recollection on my part.
