Microsoft has a matching program for employee donation. It matches dollar by dollar and even donates $17 per hour if you do volunteer work. Microsoft also have the Giving Campaign (October in the US). Here different groups compete about raising the most donations (cash). There are fund raising events like breakfast with your Senior VP being your server, or auctions (dinner at home with Bill Gates is typical a top draw ~$50,000). In 2009 the Giving Campaign raised $70 million (cash) in the US. That is $35 millions from employees (about $500 per employee) and $35 millions from MS.

I have always wondered about C++ header files. Take the Standard C++ Library, things like like the file "algorithm". Here you have the entire implementation of things like sort written as a template function which gets instantiated into actual code compiled and linked into your project. I presume such header files can be copyrighted. It actually requires thinking to do a good implementation of a template function doing sort (typically IntroSort). Since the instantiation gets compiled into your code what license covers your project?

If you run Windows, I would recommend you run with "DEP for all programs and services" with no exceptions.
