Routing Help for 2 network interfaces

I am on windows 7 Professional Edition. My PC has 2 x Network cards which are connected to two different routers. One of the interface which is 1 Gbps is connected to router which does not has internet connectivity and other connected to 1 Mbps interface has an internet connectivity.

When both networks are up and running, I am unable to access internet. To access internet I need to disable the 1 Gbps interface and thus facing a lot of issues.

I read many articles, where the routing information has been recommended to be updated. Can some one help me with routing information and a permanent solution to get rid of this issue.

Also, both interface get their IP from DHCP Servers running on Routers. This means, the IP can change any time as well.

HTML Code:

Currently Interface 1 has IP address: 192.168.1.115 (No Internet Access)
Currently Interface 2 has IP address: 10.190.63.44 (With Internet Access)

Someone please help me with routing command.

The one that I know as of now is:

Code:

route delete -p 0.0.0.0 192.168.1.115

But this command has to be executed each time windows restart and if there is a change in IP address, the command has to be modified for that as well.

I think, I was unable to explain the problem I am facing. The setup is already there. It's a Lab machine where we are connected to two different networks. For each Network a router is connected (I cannot change anything here). Also, I cannot disable any of the interfaces, doing this will disturb the whole setup. I need to update my routing table, such that all internet traffic goes to one network (always) and all other traffic (Win SCP etc.) goes to another network.

I know plugging Internet Cable in faster Gb Card, will make it work due to windows identifying faster network for internet, but I cannot do this here as I need to download heavy files from my another network (which does not has internet access). I hope I was able to explain it better this time.
