Since I install Window 7 my IE is not working but my Firefox is working fine. Is there anyway I can get my IE working again or can I remove IE from my Windows?

1. Click Orb/Control Panel/Programs/Turn Windows Features On Or Off, uncheck the box in front of Internet Explorer and click yes to the pop-up, click ok, wait for next pop-up and click Restart Now.
That removes all access to IE. To get it back just reverse the steps.
This does not uninstall it. You really don't want that.
2. (Optional) Click Orb/All Programs/Windows Updates, click on "View Update History" click on "Installed Updates" and uninstall any updates relevant to IE. When "Automatic Updates" alerts you of new updates (which will be the ones you just deleted) view the updates and right click to "Hide the IE updates" and do the same for future IE updates.
