Marco Rubio (R-FL) pointed out that Russians could attack ~50 county clerks who are on Windows 2003 and 7.

Both unsupported & w/o security updates.

One problem using Microsoft is you get MSFT; another is that when a new Windows is out, your PC is too slow. You can run Linux or an unsupported OS that doesn't even get new web browsers.

Whether Rubio is concerned or pointing out targets for Russian hackers to help Trump with, MSFT has burrowed into the govt using bribes and influence peddling.
