Learn x86 assembly

I am on Windows using FASM. Is this ok? Any tutorials? I'm not really interested in learning the winAPI, console applications are fine.

Windows is written in pure, self-modifying assembly code. Notice how you can install 15 gigs of data from a single Windows install DVD, which can only hold 5 gigs? This is because the code is dynamically generated to minimize attack vectors. Any attempt to observe the static files on the disk will change how it looks in runtime. This is also why Windows needs to be updated so often, so the running code never looks like it did before. Only the most well written virii can operate on a modern Windows system that uses self-modifying code, Address Space Layout Randomization, and Data Execution Prevention.
