User Account Control in Windows Vista improves the safety and security of your computer by preventing potentially dangerous software from making changes to your computer without your explicit consent. This feature works with Windows Defender and Internet Explorer 7 to help reduce the impact of viruses, spyware, and other threats. With User Account Control and the new Parental Controls in Windows Vista, you can easily create a separate account for each member of the family and control which websites, programs, and games each person can use and install. This helps protect your family and keeps your computer running smoothly.

Windows Vista provides two main types of user accounts, each of which will be familiar to you if you share a family PC at home or if you use a computer at the office: standard user accounts (for general users) and administrator accounts (for owners or designated administrators). You can create a separate account for every user and control which websites, programs, and games a user can use and install.

In Windows Vista, standard users are prohibited from installing most programs, changing system settings, and performing other tasks that are the province of administrators. If, as a standard user, you attempt to do something that requires administrator rights, you'll either be notified that the task is prohibited or that administrative credentials are required to proceed.

At the same time, Windows Vista extends the range of common, low-risk tasks that standard users can perform (though administrators can still choose to restrict these privileges).

Administrator privileges are essential if you are, for instance, the owner of a PC, but they can also be a liability. Online threats such as malware (including viruses and spyware) exploit administrator permissions?and they attempt to do it in secret.

Even when you use an administrator account, User Account Control provides heightened security. By default, most programs run with the permissions of a standard user, which limits the potential damage they (or malware acting through those programs) can do.

Process Explorer v11.20
By Mark Russinovich
Published: May 28, 2008
Introduction
Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.

The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.

Process Explorer works on Windows 2000 SP4 Rollup 1 or above.

The problem happens because by default Task Manager isn't launched with administrative permissions, so the replacement for it isn't either. What we'll need to do is re-map the registry entry so that you can run it through the Start++ utility's sudo command to elevate it to administrator before we start it.

First, make sure that you download and install Brandon Paddock's Start++ utility, which contains the sudo command we'll need for this. (You could also use the elevate powertoy if you were so inclined)

Now you'll need to open up your registry editor and browse to the following key. You should note that if you want to turn off the replacement of Task Manager you need only delete this key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe

Now look for the "Debugger" value in the right-hand pane and change it to point to this command string, which you'll need to modify to match your username, and the location where you put process explorer. The key thing here is that it needs to be the full path to sudo.cmd as well as the full path to process explorer.




c:\users\geek\AppData\Local\Start++\CMDs\sudo.cmd c:\users\geek\bin\processexplorer\procexp.exe

Note that there should only be a space between the two paths. After that, you should be able to replace task manager with process explorer just fine.
