You have a Windows XP-based or a Windows Vista-based computer that has Windows SteadyState installed. When you set Wind,ows Disk Protection to temporarily keep user changes, certain kinds of files that the Windows boot loader accesses are not replaced or updated.

The Media Foundation Protected Media Path executable runs within a Protected Environment (PE) when media content has DRM restrictions. This executable, mfpmp.exe, has an extensibility model for 3rd-party Media Foundation components.

The Audio Device Graph Isolation executable always runs in a PE to protect any audio content that may require DRM. The audiodg.exe binary also has an extensibility model for 3rd-party user-mode components such as Audio Processing Objects.

These components, as well as user-mode audio and video drivers, will only load into a PE if signed properly for the environment. Signing is implemented through WHQL where tied to hardware through the submission process, or using the licensed PE SDK for drivers not passing through WHQL and for other components. The PE SDK provides instructions for signing binaries through the use of catalog files.

Two issues have been identified in the use of catalog signing:

1. The catalog entries in the catalog database are not persisted through an operating system upgrade. The effect is that PE-signed components will no longer load into a PE after upgrade.
2. Performing a rollback of a PE component upgrade does not reliably replace the newer entry in the catalog database with the pre-upgrade catalog. The effect is again that the components signed by the catalog will no longer load into a PE.

When you upgrade Adobe Flash Player in Windows Internet Explorer 7 on a Windows Vista-based computer, you receive the following warning message:

A website wants to open web content using this program on your computer

This program will open outside of Protected mode. Internet Explorer’s Protected mode helps protect your computer. If you do not trust this website, do not open this program.

Name: Adobe Flash Player

Consider the following scenario:

• You access rights-protected content by using a local user account.
• You use this local user account from a computer that is located outside the domain.

In this scenario, you are not prompted for your credentials to authenticate to the Windows Rights Management Services (RMS) server. Therefore, you cannot access the rights-protected content.

This problem typically occurs in scenarios in which you log on to a home computer that is running Windows Vista by using a local user account. Then, you use Microsoft Office Outlook Web Access (OWA) to access the e-mail account from your workplace. In this scenario, you may not be prompted for your credentials to access the RMS server.

When you try to submit a fax to a fax server by using Windows Fax and Scan on a Windows Vista-based computer, the fax submission fails. Additionally, you may receive the following error message:
