so i was wondering if it is possible to make my router prioritize certain data than others like in QOS, like if i want to make downloads from the domain www.download.com to take highest priority, can i do that? . . . if not then how can i do it locally in windows if there is software for this or anything..

If you have a firmware like tomato, then you can set QOS rules on a per port basis as well as on a per data type basis via L7 filters, this allows you to have multiple different applications using the same port to also have different priorities. L7 also works well by making it so you don't have to worry about which port it uses.
You cant really do QOS on a per domain basis
Also understand that QOS does not have much of an impact on downloads.
It only takes effects when the upload is 100% saturated
While you can set download speed limits on a per priority basis, those will be in effect 24/7, so for example suppose you have a 10mbit connection and you want steam to only use 3mbit so that if steam is updating it will only use 3mbit leaving the rest for stuff like download.com
that limit wil be in effect even when you are doing nothing on download.com
so while there is no way to directly targate a domain, you can get pretty close to doing it if you skillfully use port based QOS and L7 filters and multiple priority levels.
Currently no one has designed a QOS system that works like windows or linux task manager priority settings where all processes regardless of priority have access to all resources but during times of saturation, lower priority processes will get proportionally fewer resources.
