What Linux operating system can you use to install Windows-based software right away with no software used?

Q. For example, Ubuntu needs a program called Wine to install Windows-based software. So is there another Linux OS that can install them right away? And if so, whats the lowest Linux OS memory usage?

A. Linux is Linux, Windows is Windows, the code base are different so theres no such thing, if there were, one would think no one would buy Windows anymore wont you ?

Is there a free app to monitor your system activities on Windows 7?

A. lets see:
You can measure CPU performance using /proc/cpu. You can measure ethernet performance by using /sbin/ifconfig <eth_port>. You can use df to track data written to a filesystem/mountpoint. Take a before and after snapshot using the tool of choice and determine the metric you wish to measure.
