Thanks to Lipner's SDL & executive support, Microsoft has done one of the largest 180's in the industry's history. Backward compatibility and time-to-market will continue to create problems. Yet, comparing security (even architecture) of Windows 7 with Windows 95 is almost like looking at two different companies' products.

So, I give them due credit for good effort they put in. Many other companies have yet to match that effort. It's why their stuff is the new, big target. ;)
