Continuing on from last year’s IE9 Minor Changes list, this post describes minor changes you can find in Internet Explorer 10 in the Windows 8 Consumer Preview.

Integrated Windows Authentication

Inside Internet Explorer’s Tools > Internet Options > Advanced dialog, there’s an option named Enable Integrated Windows Authentication: This preference is stored using a REG_DWORD named EnableNegotiate inside HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings. When set to 0x1, Negotiate is enabled. From time to time, users have asked what this option does and why they’d ever want to adjust…

Forcing Internet Explorer To Forget To Not Remember

All joking aside, last fall, I wrote about the variety of reasons why Internet Explorer might not offer to remember your password on a web form. As I mentioned then, you will not be re-prompted to save your password if you’ve previously declined to store the password for this username on this page by clicking “No”…

IE8 Lookahead Downloader Fixed

BackgroundLast year, I wrote about two bugs in IE8’s Lookahead Downloader that would cause IE8 to make spurious download requests for non-existent URLs. These spurious download requests generally went unnoticed by users, because the main parser would eventually retrieve the correct resource when it was needed. However, for a small number of sites (where requesting…

As mentioned back in July, IE8’s new lookahead downloader has a number of bugs which cause it to issue incorrect speculative download requests. The “BASE Bug” caused the speculative downloader to only respect the <BASE> element for the first speculatively downloaded script file. Subsequent relative SCRIPT SRCs would be combined without respecting the specified BASE,…

We made a number of major investments throughout the browser’s code to help ensure that IE users will have a great real-world experience on the web. However, it is definitely the case that some users are experiencing abnormal and suboptimal performance when browsing. This…
