How do UAC tokens work for Standard Users ? |
When a standard user logs on to Windows 7, the system will create only one access token. The token specifies the level of access that the user has. The token also contains information about Windows privileges and specific security identifiers, more commonly known as SIDs.

How do UAC tokens work for Administrative Users ? |
When an administrator logs on to a computer in Windows 7, the system creates two access tokens. The one token is an administrator token, and the other is a standard user access token.
Both the administrator access token and the standard user access token contain the same user-specific information. However, the standard user access token doesn't contain information about administrative Windows privileges or the SIDs, where the administrator access token does contain this information. |

When do windows excutable not produce a prompt ? |
Windows executables must hold two factors true:
1. they must be located in secure directories 2. Windows publisher must sign the Windows executables they must be located in secure directories, and 1. Windows executables must be located in one of the secure directories that standard users aren't allowed to modify. These directories include certain directories under Program Files, System32, most of the System32 subdirectories, and Ehome. The Program Files directories include Windows Journal and Windows Defender. the Windows publisher must sign them digitally 2. Windows publisher must sign the Windows executables digitally. All code in Windows needs to be signed by Windows publisher, which is the certificate used to sign code. |

Components of the UAC Architecture ? |
Kernel
User System |
|
UAC
The USER COMPONENT of UAC has three elements ? |
User performs an operation requiring privilege,
ShellExecute, CreateProcess. |
|
UAC
How does ShellExecute (User Element ) perform tasks ? |
When an operation calls ShellExecute, this in turn calls CreateProcess. CreateProcess must send the ERROR_ELEVATION_REQUIRED error to ShellExecute. If ShellExecute finds this, it will call the Application Information service to try to perform the task requested with the elevated prompt.
CreateProcess will reject the call with ERROR_ELEVATION_REQUIRED if the application requires elevation. |
