- The ReadKey method waits, that is, blocks on the thread issuing the ReadKey method, until a character or function key is pressed. A character or function key can be pressed in combination with one or more Alt, Ctrl, or Shift modifier keys. However, pressing a modifier key.
- Read -p 'Press enter to continue' As mentioned in the comments above, this command does actually require the user to press enter; a solution that works with any key would be: read -n 1 -s -r -p 'Press any key to continue' Explanation by Rayne and wchargin-n defines the required character count to stop reading-s hides the user's input.

Introducction
Each key is represented by one or more characters. To specify a single keyboard character, use the character itself. For example, to represent the letter A, pass in the string «A» to the method. To represent more than one character, append each additional character to the one preceding it. To represent the letters A, B, and C, specify the parameter as «ABC».
The plus sign (+), caret (^), percent sign (%), tilde (~), and parentheses () have special meanings to SendKeys. To specify one of these characters, enclose it within braces ({}). For example, to specify the plus sign, use «{+}». To specify brace characters, use «{{}» and «{}}». Brackets ([ ]) have no special meaning to SendKeys, but you must enclose them in braces. In other applications, brackets do have a special meaning that might be significant when dynamic data exchange (DDE) occurs.
Solution 2: Works in PowerShell ISE Here is a simple way to pause the script execution and wait for the user to press the ENTER key to continue. This works for both the PowerShell commandline console as well as in the PowerShell ISE. This returns the key code of the key pressed which is the row number followed by the column number. The left up and down arrow keys are grouped with row 2 as 24, 25, and 26, and the down arrow key is grouped with row 3 as 34. This returns the key code of the key pressed. Let keycode=0 print 1 'Press any key and its key code will.
To specify characters that aren’t displayed when you press a key, such as ENTER or TAB, and keys that represent actions rather than characters, use the codes in the following table.

To specify keys combined with any combination of the SHIFT, CTRL, and ALT keys, precede the key code with one or more of the following codes.
Examples
2 4 6 | [System.Windows.Forms.SendKeys]::SendWait('Hi') [System.Windows.Forms.SendKeys]::SendWait('{ENTER}') [System.Windows.Forms.SendKeys]::SendWait('{RIGHT 5}') |

Context:This morning I was standing with Ben Gelens at the coffee machine since we’re both at the same customer.
Problem:Someone walked by and asked me if there is a way for PowerShell to ask for a key to press before it continues with the script… like a pause.
Together we replied: Read-Host. However, it seems that this scripter didn’t want a pop-up… which is what Read-Host gives… in PowerShell v2 at least.
In PowerShell 5 (which is what I’ve tested) it does not provide a pop-up. It also isn’t exactly like Press Any Key To Continue since it will only continue after an ENTER.
Solution: Upgrade to the latest and greatest version of Windows (or just upgrade WMF/PowerShell).
Workaround: See below.
Powershell Wait For Key
Inside a PowerShell prompt you can do the following:
This is maybe a bit much for beginning scripters, so here’s an simpler version:
[void]($Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown')) |
Powershell Press Any Key To Continue Working
However, if you were to execute this in PowerShell ISE, you’ll get hit by an error:
Powershell 5 Press Any Key To Continue
2 4 6 | Exception calling'ReadKey'with'1'argument(s):'The method or operation is not implemented.' +$Host.UI.RawUI.ReadKey([System.Management.Automation.Host.ReadKeyOpt... +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +CategoryInfo:NotSpecified:(:)[],MethodInvocationException |
It seems that the ReadKey method isn’t implemented in the host of Windows PowerShell ISE…
So here’s some code that will offer a bit like the same functionality but in ISE (instead of any key, only ENTER will work):
Powershell Press Any Key To Continue Create
Yes, Read-Host.
All my endeavours and investigations have led me to one single conclusion: Within Windows PowerShell ISE there is only one way to get functionality that resembles the Press Any Key To Continue behaviour and that is by using Read-Host.
This is because the console in ISE isn’t a console. It resembles one, but it isn’t the PowerShell console.
I don’t know if the terminology is correct, but I think it’s something that emulates a PowerShell console 🙂
