-this kills the running miner process
1) Yes, -r 1 will take care of it as long as you add parameters in your miner(start).bat file. Paste the code in your reboot.bat
2) DEVCON is a Microsoft tool that allows "device management" from the command line. Unfortunately it's not part of Win anymore. Don't remember where I downloaded it, but remember I had to burn a ISO file from the Windows Driver Kit. You will probably find it if you google. Same as you do when you disable/enable in device manager. Added in 5 sec delay.
3) Used on a rig having Vegas and RX580's. Never tried on other cards (was when I was struggelig getting my Vega's to run properly...) Should wok fine if you add the correct PCI\VEN.... string
