overview of internet explorer 8

Microsoft Windows Internet Explorer 8 is the next version of the world’s most popular browser that has been built from the ground up to be the best browser for the way people really use the Web. Faster, easier and safer than ever before, Internet Explorer 8 optimizes developer and end-user experiences to provide a window to the Web of online services.

note - now here comes the genuine story again, you cant use this in a non genuine windows, in order to install IE 8 you must verify that you using genuine products.

Following are brief descriptions of the new Internet Explorer 8.

Smart Address Bar

The Smart Address Bar makes it easier for people to locate the sites they want to visit. It does this by efficiently matching what a consumer types into the Address Bar with titles in their History and Favorites, without duplicates.

Tab Groups

Tab Groups allow consumers to quickly discern which tabs have related content. When clicking on a link within one tab spawns another, the new tab is placed next to the originating tab, and both tabs are marked with a color.

Redesigned “New Tab” Page

The “New Tab” Page in Internet Explorer 8 has been redesigned to allow people to perform common tasks by clicking on links on the page.

Reopen Last Browsing Session

For those who accidentally close the browser or experience a crash, Internet Explorer 8 enables people to reopen their last browsing session from the most recently closed instance of Internet Explorer 8.

Enhanced Find On Page

Find On Page functionality has been enhanced to improve how consumers search for text on Web pages.

Result count

The enhanced Find On Page functionality shows how many places the search text appears on the page.

Result highlighting

The enhanced Find On Page functionality makes it so users can locate an item at a glance since it highlights all places on the page where the search text appears.

Simplified Internet Explorer Administration Kit

The Internet Explorer Administration Kit helps IT professionals easily configure deployment settings, and now has Favorites customization and the ability to import Accelerators.

Group Policy enhancements

Internet Explorer 8 allows IT administrators to control and configure browser features including Accelerators and Web Slices with more than 140 new Group Policy settings in Internet Explorer 8, bringing the total to nearly 1,500, to ease browser deployment, configuration and customization. There are multiple new Group Policy Objects in areas such as Connection limits, InPrivate, Compatibility View and SmartScreen actions.

Developer tools

Developer tools enable developers to quickly debug HTML, CSS and JScript in a visual environment. These tools have been built directly into Internet Explorer 8 with expanded functionality including a helpful menu option for choosing which application to use when viewing a Web page’s source. Developers can quickly identify and resolve issues because of the deep insight the tool provides into the DOM.

Accelerators

Accelerators give people easy access to the online services they care about most from any page they visit. Meanwhile, developers gain an easy way to extend the reach of their online services. Accelerators also allow users to browse faster by eliminating most of the clicks required to access desired content and services.

Web Slices

With Web Slices, people can see the information they want to see most often without going away from the page they are on, and developers can mark parts of Web pages as Web Slices and enable users to easily monitor the information they most frequently browse to, all while they move about the Web. Web Slices appear in the Favorites bar, where people can identify updated sites when in bold. From there, they can see a rich Web Slice visualization of their content with easy access back to the source Web page.

Instant Search Box

The enhanced Instant Search Box in Internet Explorer 8 is more helpful, making it easier for people to find content of interest and increasing the relevancy of search results. As users type a search term, they can see real-time search suggestions, including images and rich text, from their chosen search provider. There is a quick pick menu at the bottom of the Search box, enabling people to toggle back and forth between their favorite Web sites and search providers’ Search Suggestions with a simple mouse click. In addition, the enhanced Instant Search Box presents results from the user’s own Favorites and browsing History.

InPrivate

InPrivate helps to protect people’s data and privacy from being retained locally on the PC they are using. This protects against third parties who might be in a position to track a consumers’ online activities. Consumers have the ability to use either of the features (InPrivate Blocking or InPrivate Filtering) independently.

InPrivate Browsing

When activated, InPrivate Browsing helps ensure that History, temporary Internet files and cookies are not recorded on a PC after browsing. When in InPrivate Browsing, toolbars and extensions are automatically disabled, and browsing History is automatically deleted when the browser is closed.

InPrivate Filtering

InPrivate Filtering helps protect privacy by enabling the consumer to filter content coming from third parties that are in a position to track and aggregate their online behavior. Users are provided with notice, choice and control of which third parties to allow and which ones to filter.

Compatibility View

Internet Explorer 8 provides people with an easy way to fix display problems such as out-of-place menus, images and text with a Compatibility View button that displays those pages as they were designed to be viewed. Some Web sites that are designed for older browsers may not display correctly in Internet Explorer 8, which by default renders content in the most standards-compliant way possible.

Compatibility View list

Those using Internet Explorer 8 can choose to receive a list of major sites that are best viewed in Compatibility View. When navigating to a site on the list, Internet Explorer 8 will automatically display the site in Compatibility View without requiring the user to press the Compatibility View button.

Crash recovery

In Internet Explorer 8, if a tab does crash, it is automatically restored and reloaded, and any information the user may have already entered on the page (such as when writing an e-mail or filling out a form) is restored.

Delete Browsing History

Internet Explorer 8 enhances the Delete Browsing History feature by providing the ability to delete some cookies, History and other data while preserving cookies, History and other data for favorite sites.

SmartScreen Filter

Built upon the Microsoft Phishing Filter, the SmartScreen Filter helps protect customers against a broader set of phishing threats and helps protect from sites that attempt to download malicious software. The SmartScreen Filter is easy to use with enhanced user interface and warning messages to reduce users’ click-through to confirmed sites.

ClickJacking prevention

New in Internet Explorer 8 is a feature that allows Web site content owners to put a tag in a page header that will help prevent ClickJacking, a type of cross-site request forgery. ClickJacking encompasses multiple techniques that can be used to trick Web users into unwittingly clicking an obscured or hidden Web element, usually resulting in an unwanted transaction. Internet Explorer 8 will detect sites that insert the tag and give users a new error screen indicating that the content host has chosen not to allow their content to be framed, while giving users the option to open the content in a new window.

Cross-site scripting (XSS) filter

Internet Explorer 8 helps protect customers and systems from attacks that can lead to information disclosure, cookie stealing, account or identity theft, or other attempts to masquerade as the user without permission. XSS attacks have emerged as a leading exploit against Web servers and Web applications. Internet Explorer 8 has an XSS filter that is able to dynamically detect type-1 XSS (reflection) attacks.

Data Execution Prevention (DEP)

DEP, on by default in Internet Explorer 8 in Windows Vista Service Pack 1, is a security feature that can help prevent damage to computers from viruses and other security threats by preventing certain types of code from writing to executable memory space.

Per-site ActiveX

Per-site ActiveX reduces attack surface by providing an implicit SiteLock (a tool for restricting access to a specific domain) so that controls may only run from their point of installation by default. This enables users and administrators to manage where a given ActiveX Control is allowed to run.

Per-user ActiveX

Per-user ActiveX allows developers to write their ActiveX Controls so that when a user installs them, they are installed only for that user and not for all users on the system, providing a level of protection for other users against malicious or badly written controls.

When this feature is enabled, you won’t leave a single browsing fingerprint behind for others to discover. You can slip in and out of private browsing mode quickly, so it’s easy to return to what you were doing before as if nothing ever happened (you can also browse privately all the time)


Forget This Site

new Having second thoughts about having visited a certain Web site? With this feature, you can remove every trace of that site from your browser—no questions asked!


Anti-Malware

improved Firefox protects you from viruses, worms, trojan horses and spyware. If you accidentally access an attack site, it will warn you away from the site and tell you why it isn’t safe to use. Firefox checks every part of a Web page before loading it to make sure nothing harmful is sneaking in the back door.


Parental Controls

Enforce parental control settings you’ve entered on Vista—stop unwanted downloads and more.


Clear Recent History

improved Clear all your private data or just your activity over the past few hours with a few quick clicks. You have full control over what to delete, and then your info is gone for good—on your own computer or the one at your local library. It’s that easy.


Anti-Virus Software

Firefox integrates elegantly with your antivirus software. When you download a file, your computer’s antivirus program automatically checks it to protect you against viruses and other malware, which could otherwise attack your computer.


Pop-Up Blocker

Banish pop-ups (and pop-under windows) from your surfing experience once and for all. Or, find a happy medium—choose to view blocked pop-ups or create an “allow” list of sites whose pop-ups you’re okay with seeing.


Customized Security Settings

Control the level of scrutiny you’d like Firefox to give a site and enter exceptions—sites that don’t need the third degree. Customize settings for passwords, cookies, loading images and installing add-ons for a fully empowered Web experience.


Automated Update

Our open-source security strategy lets us find—and fix—security issues in record time, making Firefox the safest way to surf. Install upgrades when you receive automatic notification or wait until you’re ready.


Anti-Phishing

Shop and do business safely on the Internet. Firefox gets a fresh update of web forgery sites 48 times in a day, so if you try to visit a fraudulent site that’s pretending to be a site you trust (like your bank), a browser message—big as life—will stop you.


Add-ons

Firefox looks for a secure connection before installing or updating add-ons, 3rd party software, and Personas.


Password Manager

We’ve seamlessly integrated this feature into your surfing experience. Choose to “remember” site passwords without intrusive pop-ups. Now you’ll see the “remember password” notification integrated into your view at the top of the site page.


Add-ons Manager

Find and install add-ons directly in your browser. You no longer need to visit the add-ons Web site—instead simply fire up the Add-ons Manager. Not sure which add-on is right for you? Ratings, recommendations, descriptions and pictures of the add-ons in action help you make your selection. The fully integrated add-on manager even lets you view, manage and disable third-party plug-ins in a few easy clicks.


Tags

improved Label a site with names or categories that are meaningful to you. For example, you can label the site www.bbc.co.uk with the “news” tag as well as the “foreign investments” tag, plus give www.nytimes.com the “news” tag, too. When you enter “news” into the location bar, both sites will be shown as results. A single site can have multiple tags, and there’s no limit to the number of tags you can create. You may not remember the exact name of a site, but with a tag, you’ll be able to find it in a way that makes sense to you.


One-Click Bookmarking

Manage your bookmarks a lot or a little. One click on the star icon at the end of the location bar bookmarks a site. Two clicks and you can choose where to save it and whether to tag it. File bookmarked sites in easy-to-access folders and organize according to theme (like “job search” or “favorite shopping”). Find your bookmarked sites in a flash by entering the tag, page or bookmark name into the location bar. The more you use your tags and bookmark names in the location bar, the more the system will adapt to your preferences.


RSS Feed Reader

You can read feeds using an online Web service, a client-side feed reader or by creating a Firefox Live Bookmark. So there’s no need to comb the Web for the latest news and updates. See the latest headlines in the toolbar or menu and go directly to the articles that catch your eye.


Download Manager

Download files seamlessly and securely! A pause and resume feature means there’s no need to wait for a download to finish before you disconnect. So, if you’re halfway through the latest White Stripes album and it’s time to catch the bus, just pause and pick up downloading when you get home. The resume function also works if your system crashes or is forced to restart. The manager shows your download progress and lets you search your files by name or the Web address where the download came from.


Spell Checking

A built-in spell checker lets you enter text directly into Web pages—like blog posts and Web-based email—without worrying about typos and misspellings. Work directly with the Web and save yourself a step.


Session Restore

improved Restart the browser without losing your place after you install an add-on or software update. And, if Firefox or your computer unexpectedly closes, you don’t have to spend time recovering data or retracing your steps through the Web. If you’re in the middle of typing an email, you’ll pick up where you left off, even down to the last word you typed. Session Restore instantly brings back your windows and tabs, restoring text you entered and any in-progress downloads.


Full Zoom

Visit your favorite news page and read the caption under the picture—or view the picture itself in a size you can see. An elegant new zoom feature lets you swoop in and see entire web pages. They scale in the way you’d expect them to, with all the elements of a page’s layout expanding equally, so you can zero in on what matters.


Tabs

At first glance, they look like little labels living above the site you’re currently visiting. But they are a brilliant way to browse multiple sites at once. Simple and easy, you can think of them as the electronic version of a well kept filing cabinet, with the tabs as the dividers and the sites as the content kept in folders. Each new site appears as a new tab (not a new window) and can be accessed in one click.


Reopen Closed Tabs

If you accidentally close a tab, you can reopen it in one click. Just view Recently Closed Tabs in the History menu and select the tab you’d like to reopen.


Save on Exit

When you quit Firefox, you can save your tabs and windows for the next time you start. No need to reopen all your windows each time you start a session.


Smooth Scrolling

Like to have all 20 of your favorite pages open at once? An elegant new feature lets you scroll through tabs easily to see them all and access the one you want quickly.


Integrated Web Search

Searching the Web is a breeze with the search box inline, just to the right of your location bar. Select the search engine of your choice and type what you want to find directly into the box. The width is adjustable so you can make it bigger if you need more space.


Hundreds of Search Engines

Access your favorite search engines quickly from the integrated search bar. You can use a new engine for each search, or stick to your favorite. Choose from a preset dropdown list of engines or select “manage search engines” from the same list to browse search engine options offered as add-ons.


Web Application Integration

Expand the power of Web-based applications. In the past you’d click on an email address in a Web site and your computer’s default email application would open up to send a message to the linked address—even if you never email through the program. Now you can choose a Web mail clients (like Hotmail, Gmail or Yahoo! Mail) to launch when you click on that email address.


Offline Browsing

improved Take your computer offline and still have information at your fingertips. Certain enabled sites may allow applications—like your Web-based email—to stay with you at all times.


Open Video and Audio

new Introducing the future of online media! Firefox is the first browser to support open video and audio formats, allowing practically limitless new ways for sites to display rich content. The open formats also allow modern web pages to display media without requiring a plug-in or a proprietary software download.

how to resolve windows socket errors

cannot browse internet or local network? displaying errors looks like one of below

  • " unable to initialize windows socket interface error code 0, IPMONTR.DLL failed to start with error code 10107 "
  • " An error occurred while renewing interface 'Internet': An operation was attempted on something that is not a socket "
  • " An error occurred while renewing interface Local Area Connection: the requested service provider could not be loaded or initialized "
  • " The page cannot be displayed "
  • " An error occurred while renewing interface local area connection: an operation was attempted on something that is not a socket. Unable to contact driver Error code 2 "
  • " The operation failed since no adapter is in the state permissible for this operation "
  • " The attempted operation is not supported for the type of object referenced "


the meaning of these errors are the Winsock registry keys are damaged or corrupted.

how to determine the winsock2 key is corrupted for windows xp, use one of the following methods.

method 1 - Netdiag tool

To use the Netdiag tool, you must install the Microsoft Windows XP Support Tools. To do so, follow these steps
  • Insert your Windows XP Setup CD, and then locate the Support\Tools folder.
  • Double-click the Setup.exe file.
  • Follow the steps on the screen until you reach the Select An Installation Type screen.
  • On the Select An Installation Type screen, click Complete, and then click Next.
When the installation is complete, follow these steps
  • Click Start, click Run, type Command, and then click OK
  • Type netdiag /test:winsock, and then press ENTER.
The Netdiag tool will return the test results for several network components, including the Winsock. For more details about the test, use /v at the end of the netdiag command: netdiag /test:winsock /v

method 2 - use the Msinfo32 program

note -
Use this method only if you do not have a Windows XP Setup CD and you do not have Support Tools installed.

  • Click Start, click Run, type Msinfo32, and then click OK.
  • Expand Components, expand Network, and then click Protocol.
  • You will have ten sections under Protocol. The section headings will include the following names if the Winsock2 key is undamaged:
    • MSAFD Tcpip [TCP/IP]
    • MSAFD Tcpip [UDP/IP]
    • RSVP UDP Service Provider
    • RSVP TCP Service Provider
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...

    If the names are anything different from those in this list, the Winsock2 key is corrupted, or you have a third-party add-on, such as proxy software, installed.
If you have a third-party add-on installed, the name of the add-on will replace the letters "MSAFD" in the list.

If there are more than ten sections in the list, you have third-party additions installed.

If there are fewer than ten sections, there is information missing.

manual steps to recover from winsock2 corruption

step 1

to repair winsock in windows xp
  • go to the command prompt
  • type netsh winsock reset at the command prompt, and then press ENTER.

  • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
  • When you are prompted to confirm the deletion, click Yes.
note - Restart the computer after you delete the Winsock keys. Doing so causes the Windows XP operating system to create new shell entries for those two keys. If you do not restart the computer after you delete the Winsock keys, the next step does not work correctly.
