App Installer is a software component of Windows 10, introduced in the 2016 Anniversary Update, used for the installation and maintenance of applications packaged in .appx or .appxbundle installation packages; they are loosely relational databases with an XML app manifest. The .appx and .appxbundle files contain either a Win32 or a Universal Windows Platform app, icons for the Start menu and taskbar, a virtualized version of any Windows Registry keys needed, and any other assets needed for the installed app to function.
The only other Windows components capable of installing APPX packages are Windows Store and Windows PowerShell. However, the latter requires Developer Mode to be turned on. App Installer provides a more user-friendly interface that is opened by clicking on the installation package.
The design for App Installer is similar to the one for the classic Windows Installer, which installs stand-alone MSI files. It shows the app name, the developer, the app's Start menu tile, and a set of capabilities enabled by the app manifest. If the user clicks the Install button at the bottom right corner, the App Installer checks the app's digital certificate. Unlike a standalone installer, App Installer refuses to install an app without a valid digital certificate. If the certificate is valid, the app displays a blue installation progress bar and shows the user a button to launch the app once it is fully installed.
App Installer is physically more flexible than Windows Installer. It can be resized and viewed in full-screen mode and the background changes based on the system-wide light or dark mode. Apps installed with App Installer can be updated through the Windows Store. It is also possible to update an app with App Installer by opening package with a higher version number than the one installed. Since APPX installations are sandboxed, unlike traditional software, it is possible to run multiple installations at once.

MATLAB (matrix laboratory) is a multi-paradigm numerical computing environment and proprietary programming language developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, C#, Java, Fortran and Python.
Although MATLAB is intended primarily for numerical computing, an optional toolbox uses the MuPAD symbolic engine, allowing access to symbolic computing abilities. An additional package, Simulink, adds graphical multi-domain simulation and model-based design for dynamic and embedded systems.
As of 2018, MATLAB has more than 3 million users worldwide. MATLAB users come from various backgrounds of engineering, science, and economics.Technical features new to Windows Vista
Windows Vista (formerly codenamed Windows "Longhorn") has many significant new features compared with previous Microsoft Windows versions, covering most aspects of the operating system.
In addition to the new user interface, security capabilities, and developer technologies, several major components of the core operating system were redesigned, most notably the audio, print, display, and networking subsystems; while the results of this work will be visible to software developers, end-users will only see what appear to be evolutionary changes in the user interface.
As part of the redesign of the networking architecture, IPv6 has been incorporated into the operating system, and a number of performance improvements have been introduced, such as TCP window scaling. Prior versions of Windows typically needed third-party wireless networking software to work properly; this is no longer the case with Windows Vista, as it includes comprehensive wireless networking support.
For graphics, Windows Vista introduces a new as well as major revisions to Direct3D. The new display driver model facilitates the new Desktop Window Manager, which provides the tearing-free desktop and special effects that are the cornerstones of the Windows Aero graphical user interface. The new display driver model is also able to offload rudimentary tasks to the GPU, allow users to install drivers without requiring a system reboot, and seamlessly recover from rare driver errors due to illegal application behavior.
At the core of the operating system, many improvements have been made to the memory manager, process scheduler, heap manager, and I/O scheduler. A Kernel Transaction Manager has been implemented that can be used by data persistence services to enable atomic transactions. The service is being used to give applications the ability to work with the file system and registry using atomic transaction operations.Windows Vista networking technologies
In computing, Microsoft's Windows Vista and Windows Server 2008 introduced in 2007/2008 a new networking stack named Next Generation TCP/IP stack,
to improve on the previous stack in several ways.
The stack includes native implementation of IPv6, as well as a complete overhaul of IPv4. The new TCP/IP stack uses a new method to store configuration settings that enables more dynamic control and does not require a computer restart after a change in settings. The new stack, implemented as a dual-stack model, depends on a strong host-model and features an infrastructure to enable more modular components that one can dynamically insert and remove.
