Can I reinstal Internet Explorer?

Are you talking about the File, Edit, View, Favorites, Tools, and Help menu at the top? They're still there, just hidden. It's kind of a pain in the a$s... Anyway, press the Alt key, and you'll see them. There's a registry hack to get them back permanently, but I don't feel like looking it up at the moment.

Yes.you can. Go to support.microsoft.com & type IE7 in search option. You will find the download particulars of IE7. Click to download IE7

Even in yahoo website,download of IE7 provided by yahoo, is also available.

yes but you should seriously consider downloading Mozilla Firefox once you are able to get back online again and avoid using Internet Explorer at all costs. It's unreliable and causes way more problems that Firefox ever has.

Yes also you can go to google.com type internet explorer dowloads. Also you might want a second broser such as firefox for just such an occasion.

yes go to start menue ,control panel, add or remove programs, then on the left side click on add/remove window component then check mark th internet explorer sign and then click next
