Anything you do from then on has no idea that you would be outside of the UK - because 100% of the internet traffic from your PC would be tunneled through the VPN. Like I said, it's pretty much the same thing as if your pc was in the UK.
Another option for you would be to install software such as gotomypc.com on your local computer in the UK, and when you get to the states, just use the gotomypc software and it will let you use your computer back home, as if you were right there. There are numerous alternatives to the gotomypc software, some of which are free.
