Following this mindset, the UAC should not be trusted to restrict access to administrative privileges. Get our RSS feed.

Opening the saved document with Office will use Protected View as expected, as shown in the screenshot below: Conclusions and Recommendations Since Microsoft states that " UAC elevations are conveniences and not security boundaries ," it is important to realize the value of separate user accounts on a Windows system.
Separate user accounts are a security boundary, and therefore the way to limit access to administrative privileges is to use a separate user account that does not have administrative privileges. Do not disable the UAC, as this action can affect a system in a way that is outside the scope of just integrity levels. Some applications may inconsistently respect MOTW and some may inconsistently apply the decisions that are made based on those markings.

One of the common misconceptions about UAC and Same-desktop Elevation in particular is: it prevents malware from being installed, or from gaining administrative rights.
First, malware can be written not to require administrative rights. And malware can be written to write just to areas in the user's profile. It can be hijacked by unprivileged software that runs on the same desktop.
Same-desktop Elevation should be considered a convenience feature. From a security perspective, Protected Administrator should be considered the equivalent of Administrator. By contrast, using Fast User Switching to sign in to a different session by using an administrator account involves a security boundary between the administrator account and the standard user session.
For a Windows-based server on which the sole reason for interactive logon is to administer the system, the goal of fewer elevation prompts isn't feasible or desirable. System administrative tools legitimately require administrative rights. When all the administrative user's tasks require administrative rights, and each task could trigger an elevation prompt, the prompts are only a hindrance to productivity.
Such prompts don't improve the security posture. These prompts just encourage users to click through dialog boxes without reading them. This guidance applies only to well-managed servers. It means only administrative users can log on interactively or through Remote Desktop services. And they can perform only legitimate administrative functions.
The server should be considered equivalent to a client system in the following situations:. Also, if standard users sign in to the server at the console or through Remote Desktop services to run applications, especially web browsers, UAC should remain enabled to support file and registry virtualization and also Protected Mode Internet Explorer.
Another option to avoid elevation prompts without disabling UAC is to set the User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode security policy to Elevate without prompting.
By using this setting, elevation requests are silently approved if the user is a member of the Administrators group. However, not all operations that require administrative rights request elevation. Using this setting can result in some of the user's programs being elevated and some not, without any way to distinguish between them. For example, most console utilities that require administrative rights expect to be started at a command prompt or other program that's already elevated.
Such utilities merely fail when they're started at a command prompt that isn't elevated. Feedback will be sent to Microsoft: By pressing the submit button, your feedback will be used to improve Microsoft products and services. Privacy policy.
