Known Internet Explorer Security Feature Issues

Published: June 11, 2010

Updated: June 11, 2010

Applies To: Windows 7, Windows Vista

The enhanced security settings introduced in Windows® Internet Explorer® 7 might create compatibility issues for some Web sites and applications. This section provides an overview of the specific security features that the Internet Explorer Compatibility Test tool can test for and identify, as well as the recommended ways to address any issues.

You can address the issues identified by the Internet Explorer Compatibility Test tool and still receive the enhanced security benefits of deploying a new version of the Windows® operating system, by using one of the following two approaches:

  • Fixing the Web site or the Web application

  • Deploying a workaround

Fixing the Web Site or Web Application

Fixing the Web site or Web application by changing the code itself is typically the recommended way to address a compatibility issue uncovered by the Internet Explorer Compatibility Test tool. Although this approach may involve higher initial costs or additional development time to deploy, this kind of fix has the advantage of permanently solving the problem, and it results in no long-term maintenance or ongoing operational costs. After you change the code to eliminate the issue, all of your users will be able to access the site without experiencing an issue. However, if you do not have access to the code or if your time and resources do not permit taking advantage of this approach, an alternative fix is to deploy a workaround.

Deploying a Workaround

A workaround is a fix that involves applying alternative registry settings to address a compatibility issue. Although deploying a workaround may seem quicker and easier than rewriting the code, this approach does involve some long-term maintenance requirements. For example, you must ensure that all new users have the correct set of features disabled on their workstations or they will experience issues with the Web site or Web application. A workaround is also a less preferable approach because it may result in a reduction in security for that particular issue. However, a workaround may still be more preferable than going without the overall security enhancement that you receive by deploying Windows Vista®. You may want to think about changing registry settings as a good short-term solution while the long-term solution of changing the code is still in development.
