Download Internet Explorer 10 (IE10) Platform Preview 4 (PP4) for Windows 8 – Even More Support for HTML5 Technologies

Last Updated on Tuesday, 29 November 2011 01:50 Written by admin Tuesday, 29 November 2011 01:45

Yes, Internet Explorer 10 also supports Windows 7, but the last two platform previews can only be tested on Windows Developer Preview.


Speaking of which, testers can now download a new Platform Preview, the fourth, of Internet Explorer 10 for Windows 8. IE10 PP3 was included into Windows 8 Developer Preview. Click here to download IE10 PP4 for Windows 8.


An updated platform preview of IE10 for the     Windows Developer Preview is now available for         download. This IE10 preview adds even more support for HTML5 technologies,    enabling richer Web applications with significantly improved performance. IE10’s    hardware acceleration of technologies like SVG, CSS3 transforms and animations delivers    faster rendering than other browsers, as highlighted in this short video.

See some of the new HTML5 capabilities, performance improvements in IE10.

With this fourth Platform Preview, developers can start    working with more site-ready HTML5 technologies. You can read the full list         here in the IE10 developer guide. Here are a few highlights:

  • Cross-Origin Resource Sharing (CORS) for safe use of XMLHttpRequest across domains.
  • File API Writer support for blobBuilder allowing manipulation of large binary objects        in script in the browser.
  • Support for JavaScript typed arrays for efficient storage and manipulation of typed        data.
  • CSS user-select property to control how end-users select elements in a Web page        or application.
  • Support for HTML5 video text captioning, including time-code, placement, and captioning        file formats.

These foundational capabilities are what developers building native applications    depend on: working with binary data and files, controlling selection and hit testing    in application UI, and providing accessible video content with captioning. The features    in this platform preview are available to Web pages now, and will be available to    Metro style applications in Windows 8.

Building HTML5 Applications

This IE10 preview supports CORS (cross    origin resource sharing) to allow developers to use XMLHttpRequest to safely    request, share, and move data across applications on different domains. This is    a common pattern developers use to bring data and services together from different    applications. In this        test drive demo, you can see how CORS is used along with XMLHttpRequest,    the File API, and HTML5 progress control to deliver a smooth experience for uploading    multiple files to a service on another domain.

Click here to see    CORS used with XMLHttpRequest to upload files across domains.

Having the ability to work with binary data and files enables developers to build    new kinds of applications and experiences on the Web. This IE10 preview supports    blobBuilder from File API: Writer    for working with large binary objects (blobs) and JavaScript typed arrays. In this test drive demo,    you can see how different file types, including file types which are not natively    supported in the browser like PCX files can be read, rendered, and even have their    internal contents displayed.

Screen shot of IE Test Drive demo Binary File Inspector showing a hex dump of a PCX file and a rendering of that file using HTML5 canvas and JavaScript.

Click here to    see how JavaScript typed arrays used with File APIs to read and view binary files.

As developers build more sophisticated applications on the Web, they have more need    for precise control over how end-users select parts of the page. With CSS user select    support in IE10, developers can specify which elements in their page can be selected    by the consumer when using their applications. In this         this test drive demo, you can see how selection control is applied in a    sample blog application using the user-select property in a CSS rule.

Screen shot of IE Test Drive demo User-Select showing the markup needed to restrict text selection to a portion of the Web page.

Click here to    try CSS user-select to control end-user Web page selection.

Improving Same Markup for HTML5

We continue to contribute to the     test suites under development at the HTML5 standards bodies, submitting         118 new tests to them, to further the goal of interoperability and same    markup. You can view them at the IE Test Center as well. We strongly encourage all    developers to write for HTML5 standards first by always using the HTML5 doc type    <!DOCTYPE html> in your pages.

IE10 Preview 4 introduces an updated     quirks mode that is more consistent and interoperable with the way quirks modes    works in other browsers like Firefox, Chrome, Safari, and Opera. This updated quirks    mode supports quirks for page layout, while allowing use of more up-to-date standards    features like HTML5 elements for audio, video, canvas, and more.

You can find a full list of new functionality available to developers in the IE10    developer guide here.    Download the Windows 8 developer preview    to try this update to IE10. We look forward to continued engagement with the developer    community and your feedback on Connect.

Windows 8: Windows Developer Preview License Terms

Last Updated on Thursday, 29 September 2011 09:23 Written by Mire_B Thursday, 29 September 2011 09:23

Here are the complete license terms for Windows Developer Preview. If you’re using the pre-Beta Windows 8, the one released at BUILD (Milestone 3 Build 8102), then know that you have agreed to the terms below. Can’t really call it an end user license agreement, or EULA, since this M3 release is a Developer Preview, but just license terms will do:

This document contains individual license terms for the Microsoft software products and  Sample Applications listed below:


1.   Microsoft Windows Developer Preview

2.   Sample Applications for Windows Developer Preview




These license terms are an agreement between Microsoft Corporation (or based on where you live, one of its affiliates) and you. Please read them. They apply to the pre-release software named above, which includes the media on which you received it, if any. Printed-paper license terms, which may come with the software, may replace or modify any on-screen license terms. The terms also apply to any Microsoft updates, supplements, Internet-based services, and         support services for this software, unless other terms accompany those items. If so, those terms apply.

By using the software, you accept these terms. If you do not accept them, do not use the software.

As described below, the software will automatically activate.  Using the software also operates as your consent to the transmission of certain computer information during activation and for Internet-based services.

If you comply with these license terms, you have the rights below for each license you acquire.


a.   Software License. You may install and test any number of copies of the software on your premises.  You may not test the software in a live operating environment unless Microsoft permits you to do so under another agreement.

b.   Term. The term of this agreement will expire on March 8, 2012 (“the expiration date”).  You have no right to use the software after the expiration date. Starting from the expiration date, you may not be able to access any unsaved data used with the software.  Any applications you receive through the Windows Store will also cease to be available to you in future versions, unless they are made available for re-download and you re-acquire them.  You may not receive any other notice.

c.   Product Key. The software may require a key to install or access it.  If it does, you are responsible for the use of keys assigned to you. You should not share the keys with third parties.


a.   Font Components. While the software is running, you may use its fonts to display and print content. You may only

·     embed fonts in content as permitted by the embedding restrictions in the fonts; and

·     temporarily download them to a printer or other output device to print content.

b.   Icons, images and sounds. While the software is running, you may use but not share its icons, images, sounds, and media. The sample images, sounds and media provided with the software are for your non-commercial use only.

c.   Client Hyper-V.  You may use the Client Hyper-V technology in the software to create a virtual instance, if the software you are virtualizing permits you to do that.

d.   Use with Virtualization Technologies. Instead of using the software directly on a computer, you may install and use the software (including a virtual instance made using the Client Hyper-V technology in the software) within a virtual (or otherwise emulated) hardware system, but the same license rights apply to the virtual instance. If you use the software in a virtualized environment, content protected by digital rights management technology or any full volume disk drive encryption technology may not be as secure as protected content not in a virtualized environment. You should comply with all domestic and international laws that apply to such protected content.

e.   Related Media Information. If you request related media information as part of your playback experience, the data provided to you may not be in your local language. Some countries or regions have laws and regulations which may restrict or limit your ability to access certain types of content.

3.   MANDATORY ACTIVATION.  The purpose of activation is to prevent unlicensed use of the software.  Activation occurs automatically the first time you use the software if the licensed computer is connected to the Internet.  If you cannot activate the software when you first use it, the software will periodically remind you to activate it. You may not bypass or circumvent activation. 

      a.  How it Works.  Activation associates the use of the software with a specific computer, and verifies that the software has been properly licensed and contains no unauthorized changes to the licensing or activation functions of the software. The software will notify you whether the installed copy of the software is properly licensed. During activation, the software will send information about the software and your computer to Microsoft. This information includes the version, language and product key of the software, the Internet protocol address of the computer, and information derived from the hardware configuration of the computer. For more information about activation, see Microsoft does not use the information to identify or contact you. If the licensed computer is connected to the Internet, the software will automatically connect to Microsoft for activation.

      b.  Re-activation. Changes to your computer components or the software may require re-activation of the software.  The same information that is sent to Microsoft during activation may also be sent during re-activation.

      c.  Activation Failure.  The software will notify you if the installed copy of the software is improperly licensed or includes unauthorized changes.  If that happens, you may not be able to obtain certain updates or upgrades from Microsoft.

      d.  Updates and Upgrades.  You may only obtain updates or upgrades for the software from Microsoft or authorized sources. For more information on obtaining updates from authorized sources see

4.   POTENTIALLY UNWANTED SOFTWARE. If turned on, Windows Defender will search your computer for “spyware,” “adware” and other potentially unwanted software. If it finds potentially unwanted software, the software will ask you if you want to ignore, disable (quarantine) or remove it. Any potentially unwanted software rated “high” or “severe,” will automatically be removed after scanning. Removing or disabling potentially unwanted software may result in

·     other software on your computer ceasing to work, or

·     your breaching a license to use other software on your computer.

By using this software, it is possible that you will also remove or disable software that is not potentially unwanted software.

5.   INTERNET-BASED SERVICES AND COMPONENTS. Microsoft provides Internet-based services and components with the software. Some of those services and components may be delivered at a later date via Windows Update–if, for example, you acquire an application that relies on one of those services or components.

a.   Consent for Internet-Based Services. Because this software is a pre-release version, we have turned on some Internet-based features by default to obtain feedback about them. The software features described below and in the Windows Privacy Statement connect to Microsoft or service provider computer systems over the Internet. In some cases, you will not receive a separate notice when they connect. In some cases, you may switch off these features or not use them. For more information about these features, see the Windows Privacy Statement at By using these features, you consent to the transmission of this information. Microsoft does not use the information to identify or contact you.


Computer Information. The following features use Internet protocols, which send to the appropriate systems computer information, such as your Internet protocol address, the type of operating system, browser and name and version of the software you are using, and the language code of the computer where you installed the software. Microsoft uses this information to make the Internet-based services available to you.


·     Plug and Play and Plug and Play Extensions. You may connect new hardware to your computer, either directly or over a network. Your computer may not have the drivers needed to communicate with that hardware. If so, the update feature of the software can obtain the correct driver from Microsoft and install it on your computer. An administrator can disable this update feature.


·     Windows Update. To enable the proper functioning of the Windows Update service in the software (if you use it), updates or downloads to the Windows Update service will be required from time to time and downloaded and installed without further notice to you.


·     Web Content Features. Features in the software can retrieve related content from Microsoft and provide it to you. Examples of these features are clip art, templates, online training, online assistance and Appshelp. You may choose not to use these web content features.


·     Digital Certificates. The software uses digital certificates. These digital certificates confirm the identity of Internet users sending X.509 standard encrypted information. They also can be used to digitally sign files and macros, to verify the integrity and origin of the file contents. The software retrieves certificates and updates certificate revocation lists over the Internet, when available.


·     Auto Root Update. The Auto Root Update feature updates the list of trusted certificate authorities. You can switch off the Auto Root Update feature.


·     Windows Digital Rights Management Technology. Content owners use digital rights management technology, including Windows Media Digital Rights Management (WMDRM), to protect their intellectual property, including copyrights. This software and third party software use this technology to play and copy protected content. If the software fails to protect the content, content owners may ask Microsoft to revoke the software’s ability to use protection technology to play or copy protected content. Revocation does not affect other content. When you download licenses for protected content, you agree that Microsoft may include a revocation list with the licenses. Content owners may require you to upgrade Windows DRM technology to access their content. Microsoft software that includes DRM will ask for your consent prior to the upgrade. If you decline an upgrade, you will not be able to access content that requires the upgrade. You may choose not to use applications that make use of DRM features that access the Internet. When these features are off, you can still play content for which you have a valid license.


·     Windows Media Player. When you use Windows Media Player, it checks with Microsoft for

·     compatible online music services in your region; and

·     new versions of the player.


  • For more information, go to

·       Feedback Features. The Customer Experience Improvement Program automatically sends to Microsoft anonymous information about your hardware and how you use this software.  Windows Error Reporting automatically sends reports to Microsoft that describe which software components had errors.  These reports may include memory dumps.  From time-to-time, we will also download a small file to your computer that permits us to collect information about specific errors you have while using the software.  The data collected by these features helps us improve our software.
