https://stackoverflow.com/questions/714877/setting-windows-powershell-environment-variables "If, some time during a PowerShell session, you need to append to the PATH environment variable temporarily, you can do it this way: $env:Path += ";C:\Program Files\GnuWin32\bin" " I'd say No.

You are right. To make a persistent change to an environment variable on Windows, use the System Control Panel. Select Advanced System Settings. On the Advanced tab, click Environment Variable.... You can add or edit existing environment variables in the User and System (Machine) scopes. Windows writes these values to the Registry so that they persist across sessions and system restarts. Alternately, you can add or change environment variables in your PowerShell profile. This method works for any version of PowerShell on any supported platform. Example: $path = [Environment]::GetEnvironmentVariable('PSModulePath', 'Machine') $newpath = $path + ';C:\Program Files\Fabrikam\Modules' [Environment]::SetEnvironmentVariable("PSModulePath", $newpath, 'Machine') https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_environment_variables?view=powershell-7.1 Answer is NO

I think it's Yes. It seems that it's the profile option. "On Windows, there are three methods for making a persistent change to an environment variable: setting them in your profile, using the SetEnvironmentVariable method, and using the System Control Panel." https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_environment_variables?view=powershell-7

Sorry, it's NO. The profile method needs to update a file located here $PROFILE and add the variables needed.

ChatGPT says YES : Yes, running the command "$env:Path += ";d:\scripts"." in PowerShell will add the path "D:\Scripts" to the system's PATH environment variable. This will allow you to run PowerShell scripts located in the "D:\Scripts" folder without specifying the full path to the script. This change will persist between PowerShell sessions, allowing you to run the scripts from any location in the command prompt.

The solution you provided using the `$env:Path` command is not persistent between sessions. The System Control Panel is a better option to make persistent changes to environment variables on Windows. Therefore, the correct answer is B. No. To make a persistent change to the PATH environment variable using the System Control Panel, follow these steps: 1. Open the System Control Panel by pressing the Windows key + Pause/Break 2. Click on the Advanced system settings link on the right-hand side of the window. 3. Click on the Environment Variables button. 4. Under System Variables, scroll down and find the Path variable. 5. Select the Path variable and click on Edit. 6. Click on New and add the path to the D:\Scripts folder (e.g., D:\Scripts). 7. Click OK to close all the windows.

After making this change, you will be able to run PowerShell scripts located in the D:\Scripts folder without specifying the full path, and the change to the PATH environment variable will persist across sessions and system restarts. Alternatively, you can also add or change environment variables in your PowerShell profile. This method works for any version of PowerShell on any supported platform.

A. Yes. The command "$env:Path += ";d:\scripts"" is a valid solution to add the "D:\Scripts" folder to the system path so that you can run PowerShell scripts in that folder without specifying the full path. This command will append the string ";d:\scripts" to the existing value of the PATH environment variable for the current PowerShell session. The semicolon (;) separates each path in the PATH environment variable. The backslash () at the end of the path is required to ensure that the path is interpreted as a folder and not a file.

I also believe this question does not reflect the answer clearly. Question 84 (which is part this series of questions) is more efficient to drive you to the System Properties.
