User Account Control (UAC) is a mandatory access control enforcement feature introduced with Microsoft's Windows Vista [1] and Windows Server 2008 operating systems, with a more relaxed [2] version also present in Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows 8.1, Windows Server 2012 R2, Windows 10, and Windows 11.
To avoid this and maintain optimal system security on pre-UAC Windows systems, it is recommended to simply authenticate when necessary from a standard user account, either via a password set to the built-in administrator account, or another administrator account. In Windows Vista/7/8/10/11 administrator accounts, a prompt will appear to ...
The initial version of cmd.exe for Windows NT was developed by Therese Stowell. [6] Windows CE 2.11 was the first embedded Windows release to support a console and a Windows CE version of cmd.exe. [7] The ReactOS implementation of cmd.exe is derived from FreeCOM, the FreeDOS command line interpreter. [2]
One of UAC's features denies administrative rights to a user who accesses network shares on the local computer over a network, unless the accessing user is registered on a Windows domain or using the built in Administrator account. If not in a Windows domain it is possible to allow administrative share access to all accounts with administrative ...
The Security Account Manager (SAM) is a database file [1] in Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7, 8.1, 10 and 11 that stores users' passwords. It can be used to authenticate local and remote users. Beginning with Windows 2000 SP4, Active Directory authenticates remote users.
Windows 10: Windows Command Prompt: Text-based shell (command line interpreter) that provides a command line interface to the operating system Windows NT 3.1: PowerShell: Command-line shell and scripting framework. Windows XP: Windows Shell: The most visible and recognizable aspect of Microsoft Windows.
Without cryptographic protection of a hardware (TPM) supported secure boot environment, PBA is easily defeated with Evil Maid style of attacks. However, with modern hardware (including TPM or cryptographic multi-factor authentication) most FDE solutions are able to ensure that removal of hardware for brute-force attacks is no longer possible.
The easier a password is for the owner to remember generally means it will be easier for an attacker to guess. [12] However, passwords that are difficult to remember may also reduce the security of a system because (a) users might need to write down or electronically store the password, (b) users will need frequent password resets and (c) users are more likely to re-use the same password ...
