Let us see what some of these handy features are. Upon launching the application, you will see a window such as the one shown below. Apart from the basic calculations which can be performed from the keypad, the top bar consists of various features. You can check the old calculations performed by clicking the clock-like icon on the top-right, or click on the middle button to keep the calculator always on top of other applications.
The Standard indicates that the calculator is currently in Standard mode, which can be changed by clicking on the three bars left of it. Upon clicking the three bars, you are presented with a list of options to choose from. The calculator can be converted into the Scientific mode for more complex calculations, or into Graphical mode to plot graphs from equations. The Programmer mode can be used to convert values between decimals, hexadecimal, octanes, or binary.
Going further down the menu, the calculator also offers a range of different converts for instant results. These features indicate that this application can be extremely useful even when performing daily regular tasks. If you are experiencing problems with your Calculator app, you can choose any or all of the following solutions to bring it back to life. The first approach should be to check for any pending updates, both in Windows Updates as well as the Microsoft Store.
Any pending updates can cause an application to malfunction. Once all the applications have been updated, including Windows Calculator, relaunch the application and check if the error is resolved.
Often Windows files are corrupted or accidentally deleted, which causes some of the apps to malfunction. A quick command can be used to rebuild those files and run the applications smoothly.
The command will take a while to execute completely. When done, recheck if the Windows Calculator is functional now. Windows Troubleshooter is a built-in utility in Windows 10 that can be used to resolve day-to-day errors experienced within the operating system.
Lets see how this utility can be used to troubleshooter the Calculator. Now scroll to the bottom of the screen, click on Windows Store apps , and then Run the troubleshooter. A new wizard will launch to automatically detect the problems of any Windows applications.
Go through with the wizard and perform any necessary actions recommended by it. When completed, recheck the application for any errors. You can also try to reset the Windows Calculator application in order to restore its standard functionality. Note that this will erase all history within the application, and reset any changes made. The application has now been reset and should be fully functional. If a command is a standalone executable program, PowerShell launches it in a separate process ; if it is a cmdlet, it executes in the PowerShell process.
PowerShell provides an interactive command-line interface , where the commands can be entered and their output displayed. The user interface offers customizable tab completion. PowerShell enables the creation of aliases for cmdlets, which PowerShell textually translates into invocations of the original commands. PowerShell supports both named and positional parameters for commands. In executing a cmdlet, the job of binding the argument value to the parameter is done by PowerShell itself, but for external executables, arguments are parsed by the external executable independently of PowerShell interpretation.
NET type system, but with extended semantics for example, propertySets and third-party extensibility. For example, it enables the creation of different views of objects by exposing only a subset of the data fields, properties, and methods, as well as specifying custom formatting and sorting behavior.
These views are mapped to the original object using XML -based configuration files. Cmdlets are specialized commands in the PowerShell environment that implement specific functions. These are the native commands in the PowerShell stack. Cmdlets follow a Verb - Noun naming pattern, such as Get-ChildItem , which makes it self-documenting code. If a cmdlet outputs multiple objects, each object in the collection is passed down through the entire pipeline before the next object is processed.
Cmdlets are specialized. NET classes , which the PowerShell runtime instantiates and invokes at execution time. Cmdlets derive either from Cmdlet or from PSCmdlet , the latter being used when the cmdlet needs to interact with the PowerShell runtime. Whenever a cmdlet runs, PowerShell invokes these methods in sequence, with ProcessRecord being called if it receives pipeline input.
The class implementing the cmdlet must have one. NET attribute — CmdletAttribute — which specifies the verb and the noun that make up the name of the cmdlet. Common verbs are provided as an enum. If a cmdlet receives either pipeline input or command-line parameter input, there must be a corresponding property in the class, with a mutator implementation. PowerShell invokes the mutator with the parameter value or pipeline input, which is saved by the mutator implementation in class variables.
These values are then referred to by the methods which implement the functionality. Properties that map to command-line parameters are marked by ParameterAttribute [34] and are set before the call to BeginProcessing.
Those which map to pipeline input are also flanked by ParameterAttribute , but with the ValueFromPipeline attribute parameter set. The implementation of these cmdlet classes can refer to any. NET language. In addition, PowerShell makes certain APIs available, such as WriteObject , which is used to access PowerShell-specific functionality, such as writing resultant objects to the pipeline.
Cmdlets can use. Data stores are exposed using drive letters , and hierarchies within them, addressed as directories. Windows PowerShell ships with providers for the file system , registry , the certificate store, as well as the namespaces for command aliases, variables, and functions. Other applications can register cmdlets with PowerShell, thus allowing it to manage them, and, if they enclose any datastore such as a database , they can add specific providers as well.
The number of cmdlets included in the base PowerShell install has generally increased with each version:. Cmdlets can be added into the shell through snap-ins deprecated in v2 and modules; users are not limited to the cmdlets included in the base PowerShell installation.
PowerShell implements the concept of a pipeline , which enables piping the output of one cmdlet to another cmdlet as input. For example, the output of the Get-Process cmdlet could be piped to the Where-Object to filter any process that has less than 1 MB of paged memory , and then to the Sort-Object cmdlet e. As with Unix pipelines , PowerShell pipelines can construct complex commands, using the operator to connect stages. However, the PowerShell pipeline differs from Unix pipelines in that stages execute within the PowerShell runtime rather than as a set of processes coordinated by the operating system.
Additionally, structured. NET objects, rather than byte streams , are passed from one stage to the next. Using objects and executing stages within the PowerShell runtime eliminates the need to serialize data structures, or to extract them by explicitly parsing text output. Because all PowerShell objects are. NET objects, they share a. ToString method, which retrieves the text representation of the data in an object. In addition, PowerShell allows formatting definitions to be specified, so the text representation of objects can be customized by choosing which data elements to display, and in what manner.
However, in order to maintain backward compatibility , if an external executable is used in a pipeline, it receives a text stream representing the object, instead of directly integrating with the PowerShell type system.
Windows PowerShell includes a dynamically typed scripting language which can implement complex operations using cmdlets imperatively. Variables can be assigned any value, including the output of cmdlets. Strings can be enclosed either in single quotes or in double quotes: when using double quotes, variables will be expanded even if they are inside the quotation marks. If it is used as an L-value , anything assigned to it will be written to the file.
When used as an R-value , the contents of the file will be read. If an object is assigned, it is serialized before being stored. Object members can be accessed using. The PowerShell scripting language also evaluates arithmetic expressions entered on the command line immediately, and it parses common abbreviations, such as GB, MB, and KB. Using the function keyword, PowerShell provides for the creation of functions.
A simple function has the following general look: [53]. However, PowerShell allows for advanced functions that support named parameters, positional parameters, switch parameters and dynamic parameters.
The defined function is invoked in either of the following forms: [53]. PowerShell allows any static. NET methods to be called by providing their namespaces enclosed in brackets [] , and then using a pair of colons :: to indicate the static method. There are dozens of ways to create objects in PowerShell.
Once created, one can access the properties and instance methods of an object using the. PowerShell accepts strings , both raw and escaped. A string enclosed between single quotation marks is a raw string while a string enclosed between double quotation marks is an escaped string. PowerShell treats straight and curly quotes as equivalent.
The following list of special characters is supported by PowerShell: [56]. For error handling, PowerShell provides a. NET-based exception-handling mechanism. In case of errors, objects containing information about the error Exception object are thrown, which are caught using the try PowerShell can be configured to silently resume execution, without actually throwing the exception; this can be done either on a single command, a single session or perpetually.
Scripts written using PowerShell can be made to persist across sessions in either a. Later, either the entire script or individual functions in the script can be used. Scripts and functions operate analogously with cmdlets, in that they can be used as commands in pipelines, and parameters can be bound to them. Pipeline objects can be passed between functions, scripts, and cmdlets seamlessly. To prevent unintentional running of scripts, script execution is disabled by default and must be enabled explicitly.
PowerShell scripts can be signed to verify their integrity, and are subject to Code Access Security. The PowerShell scripting language supports binary prefix notation similar to the scientific notation supported by many programming languages in the C-family.
One can also use PowerShell embedded in a management application, which uses the PowerShell runtime to implement the management functionality. Via the APIs, the application can instantiate a runspace one instantiation of the PowerShell runtime , which runs in the application's process and is exposed as a Runspace object.
When the runspace is created, the Windows PowerShell runtime initializes the instantiation, including initializing the providers and enumerating the cmdlets, and updates the SessionState object accordingly. The Runspace then must be opened for either synchronous processing or asynchronous processing.
After that it can be used to execute commands. To execute a command, a pipeline represented by a Pipeline object must be created and associated with the runspace. The pipeline object is then populated with the cmdlets that make up the pipeline.
For sequential operations as in a PowerShell script , a Pipeline object is created for each statement and nested inside another Pipeline object. The types are verified and parameters bound using reflection. If the pipeline has the Write-Host cmdlet at the end of the pipeline, it writes the result onto the console screen.
If not, the results are handed over to the host, which might either apply further processing or display the output itself. The host creates the pipeline and executes them. In fact, the interactive PowerShell console itself is a PowerShell host, which interprets the scripts entered at command line and creates the necessary Pipeline objects and invokes them. DSC allows for declaratively specifying how a software environment should be configured.
Upon running a configuration , DSC will ensure that the system gets the state described in the configuration. DSC configurations are idempotent. The Local Configuration Manager LCM periodically polls the system using the control flow described by resources imperative pieces of DSC to make sure that the state of a configuration is maintained. All major releases are still supported, and each major release has featured backwards compatibility with preceding versions. PowerShell 1. PowerShell 2.
PowerShell v2 includes changes to the scripting language and hosting API, in addition to including more than new cmdlets. New features of PowerShell 2. PowerShell 3. Microsoft has also made PowerShell 3. New features in PowerShell 3. PowerShell 4. Microsoft has also made PowerShell 4. PowerShell 5. The "Desktop" edition is the continuation of the traditional Windows PowerShell that runs on the.
NET Framework stack. The "Core" edition runs on. In exchange for smaller footprint, the latter lacks some features such as the cmdlets to manage clipboard or join a computer to a domain, WMI version 1 cmdlets, Event Log cmdlets and profiles.
PowerShell Core 6. Microsoft expects to release one minor version for PowerShell Core 6. The most significant change in this version of PowerShell is the expansion to the other platforms. For Windows administrators, this version of PowerShell did not include any major new features. In an interview with the community on 11 January , the PowerShell team was asked to list the top 10 most exciting things that would happen for a Windows IT professional who would migrate from Windows PowerShell 5.
According to Microsoft, one of the new features of PowerShell 6. PowerShell 7 is the replacement for PowerShell Core 6. New features in PowerShell 7 include: [].
PowerShell 7. It uses. NET 6. On Windows, updates to PowerShell 7. The following table contains a selection of the cmdlets that ship with PowerShell, noting similar commands in other well-known command-line interpreters. Many of these similar commands come out-of-the-box defined as aliases within PowerShell, making it easy for people familiar with other common shells to start working.
A project named Pash , a pun on the widely known " bash " Unix shell, has been an open-source and cross-platform reimplementation of PowerShell via the Mono framework. Pash development stalled in , was restarted on GitHub in , [] and finally ceased in when PowerShell was officially made open-source and cross-platform.
