User Account Control (UAC) is a technology and security infrastructure introduced with Microsoft’s Windows Vistaand Windows Server 2008 operating system. It aims to improve the security of Microsoft Windowsby limiting application software to standard user privileges until an administrator authorizes an increase in privilege level. In this way, only applications that the user trusts receive higher privileges, and malware should be kept from receiving the privileges necessary to compromise the operating system. In other words, a user account may have administrator privileges assigned to it, but applications that the user runs do not also have those privileges unless they are approved beforehand or the user explicitly authorizes it to have higher privileges.
A Windows account will only work on the computer it is created on. If you want to use a different computer, you will have to set up a Windows account on that computer.
