The unfiltered token has all the user's group memberships and privileges. The filtered token represents the user with the equivalent of standard user rights. By default, this filtered token is used to run the user's programs. The unfiltered token is associated only with elevated programs. An account is called a Protected Administrator account under the following conditions:.
User Interface Privilege Isolation UIPI : UIPI prevents a lower-privileged program from controlling the higher-privileged process through the following way: Sending window messages, such as synthetic mouse or keyboard events, to a window that belongs to a higher-privileged process. Windows Internet Explorer operates in low-privileged Protected Mode, and can't write to most areas of the file system or the registry. By default, Protected Mode is enabled when a user browses sites in the Internet or Restricted Sites zones.
PMIE makes it more difficult for malware that infects a running instance of Internet Explorer to change the user's settings. For example, it configures itself to start every time the user logs on.
Installer Detection: When a new process is about to be started without administrative rights, Windows applies heuristics to determine whether the new process is likely to be a legacy installation program. Windows assumes that legacy installation programs are likely to fail without administrative rights.
So, Windows proactively prompts the interactive user for elevation. If the user doesn't have administrative credentials, the user can't run the program. It disables all the UAC features described in this section. Legacy applications that have standard user rights that expect to write to protected folders or registry keys will fail. Filtered tokens aren't created. And all programs run with the full rights of the user who is logged on to the computer.
It includes Internet Explorer, because Protected Mode is disabled for all security zones. Any other value enables UAC. On other operating system platforms usually those with higher security requirements — such as servers and enterprise editions , UAC cannot be disabled through the UAC dialog. Regardless of which environment the operating system platform is in, the Is UAC Enabled AM object checks the value of the UAC setting based on the value of the slider bar, and reports it as disabled if the setting is set to its minimum value; any other value will report UAC as enabled.
Account Settings Logout. All Files. Select your default language. If you have multiple languages. In iTunes, choose Preferences, then click Devices. From here, you can right-click on the. This site uses cookies to store data. Programmatically you can try to read the user's token and guess if it's an admin running with UAC enabled see here. Not foolproof, but it may work. The issue here is more of a "why do you need to know" - it has bearing on the answer.
Really, there is no API because from a OS behavior point of view, what matters is if the user is an administrator or not - how they choose to protect themselves as admin is their problem. This post has sample code in C to test if UAC is on and if the current app has been given elevated rights. You can download the code and interpret as needed. The code in that post does not just read from the registry. If UAC is enabled, chances are you may not have rights to read that from the registry.
You want to check if the user is running with administrative privileges using CheckTokenMembership :. Note that if the user has changed the state of UAC but has not restarted the computer yet, this function will return an inconsistent result. This post is rather ancient, but I wanted to comment on the "why do you need to know" and "check token membership" bits.
Perhaps checking whether the user is running with admin privileges is the right thing to do in this instance, but who knows? The guidance that Microsoft gives is, at best , iffy, if not just downright confusing. For anyone else that finds this and is looking for a VBScript solution.
Here is what I came up with to detect if UAC is enabled and if so relaunch my script with elevated privileges. Just put your code in the Body function. I found there were problems with transportability between XP and Windows 7 if I wrote code to always launch elevated. Using this method I bypass the elevation if there is no UAC. Should also take into account and above server versions that have UAC enabled. So you can read this property from within. Sorry for not having more details but I hope this helps.
