1. Copy contents of CGWatcher directory to multiple folders, according to required number of CGWatchers to run (i.e., CGWatcher-1, CGWatcher-2, CGWatcher-3 etc.).
2. Configure each CGWatcher to communicate with cgminer using unique TCP port (for example, 4028,4029,2030 etc.)
3. Do not mark "Run when Windows starts" checkbox in CGWatchers, since multiple instances of CGWatchers will try to overwrite the same key in the registry.
Create unique autostart key in the registry for every instance of CGWatcher instead:
4. Reboot
