System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters]
Value Name: RandomAdapter
Data Type: REG_DWORD (DWORD Value)
Vale Data: (0 = disabled, 1 = enabled)

Create that.

There are 3rd party software solutions too.

Possible? Yes.
Practical? Not really.

It only becomes viable if your machine frequently communicates with one or more specific servers. For example, you could rig it so that all communication with FTP.SOMEDOMAIN.COM goes via NIC1, and everything else goes via NIC2. However, since most users' patterns are far more random, it becomes challenging to come up with the specific set of rules for breaking up the traffic into two separate groups.

Another way to think about it is this: if you can think of a way to describe, in technical terms, exactly what traffic should go via which interface, then it's possible (for you).

@torrentg: I'm afraid that won't work. It doesn't do what many people think it does. If you're interested in the specifics:

What H2SO4 says is spot on. In order to effectively use 2 different connections, you have build in routes on your machine to funnel traffic over 1 nic versus the other.

It might be possible to bind 1 NIC to a particular application, thus this application would always use 1 card and everything else could use the other.

However, I find most people are simply trying to double their bandwidth and instead of getting 15MB/s to the Internet, they are looking to get 30MB/s...and having 2 connections like this just isn't going to do that as people hope.

I say - get a T1 or T3 line! That extra bandwidth and speed is certainly worth the $1K to $3K per month, right?

You would need to get something more than a T1. A T1 is only 1.544Mb/s. Most home users with broadband have considerably more speed than this. The only real advantage here is that you get full speeds in both directions.

Direct line, no "garden hose" effect, much lower ping (network delay) and packet loss compared to cable/DSL... that all adds up to a faster connection in real-life tests. There's a reason why data centers don't use cable/DSL. Of course, for the typical home user, the benefits of T1/T3 don't outweigh the costs. For mission essential applications, T1 and T3 are the way to go.

Of course, you realize this was all in jest - hence the winking smiley, right? And I did misrepresent the facts - I should not have said bandwidth, since cable has a much higher bandwidth than a T1 or T3. And in today's tech savvy world, a T1 is basically a waste (except for slow cable internet subscribers like me) - but hey, I live in the past! Token-ring all the way, baby!

Hey, I've been looking for a way to load balance two WAN connections for weeks. I finally found a solution here:
Multi WAN Load Balancing under Windows with PfSense | Bora's Place
Basically you have to run a virtual machine loaded with a UNIX based router operating system. You allow it to access both NIC's, while preventing windows from using either. Then set up a virtual NIC which is served by the VM, and configure windows to route all traffic through it.
I know it seems like more trouble than it's worth, but it really does work. My Bittorent speed has increased from a maximum of 13.6Mbps to at least 21.6Mbps. You can test if it is working by going to a website that tells you your IP. If you hit refresh a few times, the listed IP will change between the two WAN IP's in your setup.
