User account control was introduced in Microsoft Windows Vista and Windows Server 2008, which is also available in Windows 7 as a standard feature. User account control is a feature rather a technology of security infrastructure introduced with the aim of improving the security in MS Windows by limiting application software to controlled user privileges until the administrator authorizes additional privileges elevated or increased. This feature helps control malware by not letting the application run without explicit user authorization. This comes very handy when dealing with executable files. With user account control the user can be assigned various privileges, password control etc.
Sometimes while running certain applications, the user finds inability to run the program. Typically Internet Explorer or Windows Explorer or common Windows problems like internet Explorer won’t work, can’t load Windows Explorer etc. This typically indicates that some of Windows’ own built in tools are broken or non-functional, not allowing the concerned application to run. Generally it is thought that one of the only ways of overcoming this problem is reinstallation of Windows.
This may not be the final necessary solution. First try other simpler methods, to evaluate how deep rooted the Windows problem is. Sometimes a Windows problem fix could also be found for typical bugs and issues, with a simple Google search. Many users complaints and technical involvements have made available solutions that they have found viable over the net.
One of the simplest methods of identifying the problem is by using a new user account. Create a spare, new user account with no restrictions and run the concerned application. If it runs you could even think of permanently changing to the new user account. Else, let’s come back to spare one and try the next available option. Sometimes, we notice that Windows profiles go corrupt over time. This corrupt profile can make your computer behave erratic. In a majority of cases, this can be easily cured by just creating a new user account profile and then, copying over to the new profile all your personal data like files, music, photos, et al. This is because bringing a corrupt profile back to normal can be very, very complex.
In the context of applications like Google Chrome, Internet Explorer, Mozilla Firefox, Adobe Reader, one of the core security features is the MIC or Mandatory Integrity Control or Integrity Level. Generally from Windows Vista onwards, there have been 4 integrity levels namely, low, medium, high and system. The user interface privilege isolation helps in the control of access to objects based on user integrity levels. The registry, processes, threads written each time for a particular user are typical factors that cause file corruption. When we create a new user, all these aspects are in default condition and Windows does not get stuck with the problems associated with the users. MSDN, Symantec, Adobe and other portals, refer this perspective in an exhaustive manner.
