IE 9 saw light of day as a finalized product in March

Microsoft fielded some questions on Monday in a Webinar on Internet Explorer 9, focusing on what IT managers should know about the new Web browser.
IE 9 saw light of day as a finalized product in March, following a year-long effort by Microsoft to create a new browser based on the developing HTML 5 specifications. Those specs are still at the Working Draft stage at the Worldwide Web Consortium, but IE 9 and other Web browsers already can take advantage of some HTML 5 features.
At present, IE 9 is just starting to take off. Net Applications' April data shows IE 9 as having a 2.4 percent market share. It's just ahead of the Opera 11 browser with 1.6 percent use, according to the data.
During the Webinar, Chris Jackson answered audience questions that Dell inspiron 5160 battery,Dell inspiron 600m battery were moderated by Kevin Remde, Microsoft's senior IT pro evangelist. Jackson is principal consultant and technical lead of the Windows application experience SWAT Team at Microsoft. He regularly focuses on application compatibility issues inhis blog.
IE 9 Notable Features
Some general IE 9 characteristics were addressed in the Webinar. IE 9 supports hardware acceleration of graphics and video, tapping the PC's graphics processing unit. The debugging of sites can be done using developer tools accessed by hitting the F12 button on the keyboard. The browser, which will run on Vista- and Windows 7-based machines, is considered to be "integrated" with Windows 7, using Windows-like features such as site-pinning and jumplists.
A Microsoft product manager explained last month in an HP support forum (sign-up required for access) that the site-pinning feature in IE 9 will only work if the user is running Windows 7.
"HTML5 will work equally fine on Windows Vista and Windows 7," the unidentified Microsoft product manager explained in the support forum. "However, the Pinned Sites feature only works in Windows 7."
Security in IE 9 is enabled through a SmartScreen filter that checks the reputation of Web sites visited. There's also a tracking protection privacy feature that can help block access to clickstream data by third-party advertisers. IE 9 can work Dell inspiron 1720 batteries with Windows Vista and Windows 7 in protected mode, which restricts the browser's privileges. Protected mode is turned on by default for restricted sites, the Internet and intranets. However, Jackson noted that Microsoft SharePoint doesn't run so well with protected mode turned on.
The browser can be managed by using Group Policy settings. It can be distributed to users via Microsoft System Center Configuration Manager and updated via Windows Update and Windows Server Update Services. Jackson said that his preference for Group Policy users is to push out a stock build of IE 9, but he acknowledged that it might not always be possible in some cases.

Migrating From IE 6 to IE 9
A lot of the talk in the Webinar centered on what to do when moving from IE 6, which shipped with Windows XP -- still the most used operating system worldwide. Jackson said that the transition from IE 6 to IE 9 is a lot like the transition from IE 6 to IE 8. He said that about 25 percent of stuff gets touched in making such a move. In a small number of cases, solving the problem may require virtualization or changing the code.
Jackson noted that right now, few tools are available to aid IT pros in making the jump from IE 6 to IE 9. TheMicrosoft Assessment and Planning Toolkit can be used Dell inspiron 1300 battery,Dell inspiron 1520 battery to show the installed base of toolbars and browser helper objects in a computing environment, but that's about it. He added that tools to help with such transitions are still evolving.
IE 9 gives users options for displaying Web content via the compatibility view button in the browser. Jackson said that compatibility view "lies about the version of the browser you are using." If a Web site doesn't display well in HTML 5 code, it's possible to roll back via the site's user-agent string (X-UA-Compatible), which is specified in the header or via a metatag.
Jackson previously discussed scenarios for enterprises to consider in setting the compatibility view for Internet Explorer in this blog post. However, he generally recommended setting a tag.
"You can choose to opt into the standards as it makes sense for your business," he explained in the Webinar.
Surprisingly, Jackson argued the case that IE 6 had high standards compliance in its day, but that was 10 years ago. It had compliance with IE 5 plus the new standards of the day. IE 9 currently has compatibility modes for IE 5.5., IE 7, IE 8 and new one for IE 9 that supports HTML 5.
