Hi Euni,
Al web browsers have a function called "favorites". Favorites is a "place" that the browser has that saves a list of websites that you want to return to by clicking on a named link that you have saved into the browsers favorites list. In that manner you don not have to type in the address of the website you wish to visit.
I'm on a old Windows XP machine at the moment which is the "same but different" from Win7 that you have but the screenshots I have will be close enough for you to get the idea. If you can stuck just post back.
I said above that you can save a "list" of places. You access that list in different ways depending on a number of setting you choose in the broswer. You seen to be using IE11 (that is the standard default browser for Win7)
Here is what my list looks like in my old XP machine. The list is built up over time:

The easiest way to access the Favorites List is from the FAVORITES tab in the MENU BAR.The MENU BAR in Win7 is at the very top of the browsers it consists of a line of words:
FILE EDIT VIEW FAVORITES TOOLS HELP
If those words already appear at the very top of you browser we are all set'
If those words are not visible we have to make them so.
Here is how we do that: Move your mouse to the very top band of the browser and RIGHT CLICK your mouse:

A pop up dialog box will open. Click the area where the check mark is next to LOCK THE TOOL BARS this will remove the check mark if it is there allowing you to make changes.
Once unlocked place a check mark in the area just to the left of MENU BAR (this will enable the FILE EDIT VIEW FAVORITES TOOLS HELP line of options to appear at the top of IE11
After doing so place, the check mark back in the area to lock the tool bar.
Once that is done the Menu Bar options should be visible at the very top of you browser.
If you then go to a website such as:
http://my.hughesnet.com/myaccountWhile there click on the FAVORITES button on the top:

Move you mouse down to the option ADD TO FAVORITES and click
That will open up a box that will allow you to name that website anything you wish to call it and that name will be added to your personalized list:

After naming it click the ADD button to effect the change.
Anytime thereafter you wish to visit that site just op the browser or open a new tab, click the word FAVORITES in the top menu bar and select the saved site from your list.
As to data amounts and service plan limits I can feel your pain. I was a HN7000s system for years. In my location they finally did launch Echostar17 that had much greater plan and speed offerings.
Hughes last month launched a new satellite. It is still going though final testing for not only the satellite but also the Gateways that serve as uplink/downlink ground side facilities.
Hughes has yet to announce coverage areas and plan offerings but I'd bet my life on the present Spaceway3/ HN9000 users being in for a drastic increase in speeds, data plans and just general reliability improvements.
You mentioned the chance of wireless service and that is good. Just be careful of the terms. As it is now if you max out with Hughes you get throttled and money spent for additional data in the form of tokens is .... optional. Some plans .. cellular based for example add extra cost data automatically without your knowledge, until the monthly bill arrives so do read and understand carefully the costs and limits.
I know the above is a bunch to swallow at one time. If you are unsure of something or have any questions please feel free to post them.
