People have routines for using their web browsers. Most of us like to have a home page, either a search engine or several websites. Personally, I prefer to bring all the websites back from my last browsing session. Here's how you can reopen a browsing session or a closed tab in Internet Explorer 11:
How To Set Internet Explorer To Reopen The Last Session
If you keep many tabs opened in your browser, you may find useful to pick up where you left off every time you open Internet Explorer. In order to do that, you need to click on the gear icon from the top right corner (or press Alt+X) and go to Internet Options.
A new window will appear, named Internet Options. Go to the General tab and check the "Start with tabs from the last session" option, from the Startup section. After that, click OK.
How To Restore The Last Session In Internet Explorer
In case you were working on something important the last time you used the browser, and you need all your tabs from the last session back, this can be done easily. Click on the New Tab button (or press CTRL+T).
On the bottom of the new tab page click the Reopen last session button. If this button is grayed out, it means that you don't have a previous session to reopen.
How To Reopen Specific Tabs In Internet Explorer
I don't think there is anyone who hasn't closed a tab by mistake. When this happens, instead of searching through the browsing history, it's much easier to press Ctrl+Shift+T to restore the tab. But maybe you want to restore a specific tab that isn't necessarily the last one you closed. You can do so by right-clicking any opened tab, and then hovering the mouse over the Recently closed tabs submenu. From there, you can also choose to open all closed tabs.
Note that this option is only for reopening the tabs closed during the current browsing session in Internet Explorer.
The features covered in this guide are very helpful for any type of user. If you closed some tabs by mistake, you can easily find them with just a few clicks, and if you work, for example, for a long time on the same project, you may want to reopen the previous browsing session.
