A malicious program could, after receiving approval from the user of coursethen modify the system and prevent UAC from operating. While Bannan talks about third party tools such as "TweakVista," he misses the fact that you can disable UAC from within Windows itself. That is, the ability to disable UAC is not an exploit, but an option in the system. Microsoft has responded to these concerns, saying that "if consent is given by the user, this then elevates the application to a higher administrative integrity level and allows privileged access to occur within the context of that application only.
Note that for this to occur, the UAC prompt requires that a user must provide consent before the application will be allowed to run. The Windows Security Center immediately notes that UAC has been turned off, and it prompts you to turn it back on using a system tray notification.
From our own testing, it appears impossible to disable UAC without the Security Center noticing it, which makes it rather unlikely that a user is end up in a less secure state. Not only would the user have to allow the malicious program to run; that user would also need to ignore the balloon notifications from the system tray. This leads us to a few observations.
How to use the UserAccountControl flags to manipulate user account properties
If you tell it that what you're installing is OK to install, it's not going to second guess you. While it is indeed true that a user could give "run permissions" to a malicious application, that is dare I say it the user's prerogative and responsibility. Second, since the system does actually monitor whether or not UAC is enabled, the amount of damage that can be done to a system after a malicious application disabled UAC should be minimal, given that the system alerts the user to this effect.
While one could arguably call this a loophole, I humbly suggest that anything that ultimately hinges on the end user's decisions can be seen as a loophole.

One way for program developers is to add a requestedPrivileges section to an XML document, known as the manifestthat is then embedded into the application. A manifest can specify dependencies, visual styles, and now the appropriate security context: An executable that is marked as "requireAdministrator" in its manifest cannot be started from a non-elevated process using CreateProcess. ShellExecute or ShellExecuteEx must be used instead.
If an HWND is not supplied, then the dialog will show up as a blinking item in the taskbar. Inspecting an executable's manifest to determine if it requires elevation is not recommended, as elevation may be required for other reasons setup executables, application compatibility. This will not allow one to detect that an executable requires elevation if one is already executing in an elevated process, however.
A new process with elevated privileges can be spawned from within a. NET application using the "runas" verb. An example using C: For example, if UAC detects that the application is a setup program, from clues such as the filename, versioning fields, or the presence of certain sequences of bytes within the executable, in the absence of a manifest it will assume that the application needs administrator privileges.
The compatibility options were also insufficient.
