There is absolutely no possible way that you can run iOS 9, with the full App Store at all, if a solution did exist, I'd be really surprised.
The closest to get iOS on a PC is to install Mac OS X in a virtual machine (that is if your PC is even compatible), then using the Mac App Store to install Xcode(which is a software development it). Xcode comes with a iOS simulator. Then you'd make a blank iOS app within Xcode, and run it. This would open the iOS simulator, and therefore have a iOS simulator/emulator.
This would take a while to setup and depending on your PC specs, might not work. Also, you'd need a Mac OS X ISO file and a copy of VMware or VirtualBox. So depending on how important this is, it might not be worth it.
