A collection of Windows XP and Windows Vista releases offered by Microsoft was refreshed earlier this week, allowing customers to download and run the two operating systems free of charge.

The Internet Explorer Application Compatibility VPC Image downloads were updated, with the previous version closing in on the expiration deadline.

The latest versions of the Windows Virtual PC VHDs continue to be time-bombed, but users have a good few months of usage before they expire.

According to the software giant, the new XP and Vista virtual images are set to expire on 05/18/2011.

The Internet Explorer Application Compatibility VPC Images are offered by Microsoft for free to help web developers that need to test their websites on different versions of IE, as well as on older Windows operating systems. More »

Microsoft has confirmed a zero-day vulnerability affecting all supported versions of Internet Explorer, including IE8, IE7 and IE6.

The Redmond company explains that the security flaw involves the creation of uninitialized memory during a CSS function within the browser.

“It is possible under certain conditions for the memory to be leveraged by an attacker using a specially crafted Web page to gain remote code execution,” the software giant informed.

Given the fact that successful exploits against this vulnerability can allow for remote code execution, and attacker could potentially take over a victim’s computer.

However, Dave Forstrom, Director, Trustworthy Computing, Microsoft denied that this has happened yet. More »

Microsoft confirmed this issue, and noted that IE9 is not to blame, but that at fault is an incompatibility between the next generation IE browser and old hardware.

It appears that reports of poor performance for IE9 came from users that compared the speed of the new browser with that of older versions of Internet Explorer. The older releases of IE were faster especially on webpages that had complex graphics.

The issue is related to the HTML5 performance enhancements built into Microsoft’s next iteration of IE.

IE9 brings to the table hardware acceleration, leveraging the computer’s GPU (graphics processing unit) in concert with the DirectX APIs in Windows 7 and Windows Vista SP2. More »

Development on the next generation of Internet Explorer continues, with the first public Beta development milestone of Internet Explorer 9 available for download since September 15th, 2010.

But while the IE team is now silent on the evolution of IE9, a third-party source claims that Microsoft is up to version 9.0.8002.6000 with the successor of IE8.

This detail remains unconfirmed by the Redmond company, an aspect which will not change, as the software giant’s policy is to not comment on leaks, rumors, etc.

In mid-September 2010 Internet Explorer 9 Beta Build 9.0.7930.16406 was released to the public, and in this regard, version 9.0.8002.6000 supersedes the original release of IE9. More »

New Internet Explorer Application Compatibility VPC Images are currently available for download free of charge from Microsoft.

The company is offering XP SP3 and Vista SP1 virtualized, packaged as Virtual Hard Disk (VHD) files, that can be used with Microsoft’s virtualization solutions.

Each XP and Vista copy brings to the table a different version of Internet Explorer. The images are designed for web devs that are building sites and need to test their projects for compatibility with multiple IE versions.

“After a little delay, the Internet Explorer App Compat Testing VHDs are now available for download on the Microsoft Download Center. Like the previous set of images, these ones are time-bombed for 90 days and will expire on January 11th, 2011,” revealed Microsoft’s Pete LePage. More »
