Best environment for code review on Windows

I've been given the following task:

A company is giving source code for its product (comprising over 1 million lines of C++, Java, with some assembly) for my review. The code will be loaded onto a Windows machine that I do not control, has no USB ports, no network, and is a small controlled room. I must somehow sift through the code, figure out where the implementation of Action X is, and then trace through the code to see how Action X ties into the rest of the product.

The last time I did this, they gave me the code along with Notepad. Since I couldn't add software, that was it. I found myself using DOS command shells to get a grep-like ability with FINDSTR /R but this was painful, as you might imagine.

I have a chance to tell them what I would like installed on the machine next time. What do you think makes sense? Ideas:

1. Ask code to be loaded into some IDE


2. Ask them to put it all in doxygen


3. Ask them to present the code in an HTML format that has cross-referenced links (sort of like MS reference code uses)

Or something else?
