PowerShell Commands

Get-Host

The Get-Host cmdlet gets an object that represents the program that is hosting Windows PowerShell.

The default display includes the Windows PowerShell version number and the current region and language settings that the host is using, but the host object contains a wealth of information, including detailed information about the version of Windows PowerShell that is currently running and the current culture and UI culture of Windows PowerShell. You can also use this cmdlet to customize features of the host program user interface, such as the text and background colors.

Out-Host

Sends output to the command line.

The Out-Host cmdlet sends output to the Windows PowerShell host for display. The host displays the output at the command line. Because Out-Host is the default, you do not have to specify it unless you want to use its parameters to change the display.

Get-Process | Out-Host -Paging

Clear-Host

The Clear-Host function removes all text from the current display, including commands and output that might have accumulated. When complete, it displays the command prompt. You can use the function name or its alias, CLS.

Clear-Host affects only the current display. It does not delete saved results or remove any items from the session. Session-specific items, such as variables and functions, are not affected by this function.

Because the behavior of the Clear-Host function is determined by the host program, Clear-Host might work differently in different host programs.

Read-Host

The Read-Host cmdlet reads a line of input from the console. You can use it to prompt a user for input. Because you can save the input as a secure string, you can use this cmdlet to prompt users for secure data, such as passwords, as well as shared data.

$pwd_secure_string = Read-Host "Enter a Password" -AsSecureString


-AsSecureString

Indicates that the cmdlet displays asterisks (*) in place of the characters that the user types as input.

Microsoft-Windows-User Profiles Service / Id: 1511

Windows cannot find the local profile and is logging you on with a temporary profile. Changes you make to this profile will be lost when you log off. Cause: This event can be caused by the following issues:   Your local profile is corrupt. You no longer have adequate privileges to the profile folders. User profile was deleted manually or by other means. A profile that is manually deleted does not remove the Security Identifier (SID) from the profile list in the registry. If the SID is present, Windows will try to load the profile by using the ProfileImagePath that points to a nonexistent path. Therefore, the profile cannot be loaded. Occasionally, Windows might not read your user profile correctly, for example, if your antivirus software is scanning your computer while you try to log on. Resolutions 1) Sign out and restart the computer Try restarting your computer and signing on with your user account again to resolve the issue. 2) Delete the error SID and ...
