Open tabs you've previously closed
This information applies to Windows Internet Explorer 8.
If you close one or more tabs during a browsing session, or close a browsing session entirely—either accidentally or on purpose—you can now use Internet Explorer 8 to reopen the tabs or browsing session that you closed.
To reopen the tabs you closed during your current browsing session
Internet Explorer keeps track of the webpage associated with each tab that you have open, including such information as the text typed into a form, and the history of how you got to that webpage. As a result, if you have several tabs open, and then close one or more, you can easily reopen any or all of them. Here's how:
In Internet Explorer, click the New Tab button.
On the new tab page, under Reopen closed tabs, find and click the address for the webpage that you want to open.
If you have changed the new tab page to your home page, you can type about:tabs in the Address bar to view the new tab page. For more information about changing what the New Tab button opens, see Open a new tab to your home page in Internet Explorer.
Internet Explorer only keeps track of history and form data for tabs that you close during your current browsing session. If you close tabs, and then end your browsing session by closing the browser, you won't be able to reopen those tabs. You can reopen that browsing session, but it will only display the tabs that were open when you closed the browser.
To reopen the last browsing session you closed
When you close Internet Explorer and end your browsing session, it keeps track of the webpages that you had open at the time. As a result, when you open a new browsing session, you can reopen the webpages that were open during your previous browsing session. Follow these steps to reopen your last browsing session:
Open Internet Explorer by clicking the Start button , and then clicking Internet Explorer.
Click the Tools button, and then click Reopen Last Browsing Session. All the webpages that you had open when Internet Explorer was last closed will open in new tabs.
