Lab answer key: Configuring Windows PowerShell, and finding and running commands

Exercise 1: Configuring the Windows PowerShell console application

Task 1: Start the console application as Administrator, and pin the Windows PowerShell icon to the taskbar

On LON-CL1, select Start.
Enter powershell to display the Windows PowerShell icon. Make sure that the icon name displays Windows PowerShell and not Windows PowerShell (x86).
Right-click Windows PowerShell or activate its context menu, and then select Run as administrator.
Make sure that the window title bar reads Administrator and doesn’t include the text (x86). This indicates that it is the 64-bit console application and that an administrator is running it.
On the taskbar, right-click the Windows PowerShell icon or activate its context menu, and then select Pin to taskbar. The Windows PowerShell console should now be open, run by Administrator, and available on the taskbar for future use.

Task 2: Configure the Windows PowerShell console application

To configure Windows PowerShell to use the Consolas font:

a. Select the control box in the upper-left corner of the Windows PowerShell console window.

b. Select Properties.

c. In the “Windows PowerShell” Properties dialog box, select the Font tab, and then, in the Font list, select Consolas.

d. Select 16 in the Size list.
To select alternate display colors, on the Colors tab, review the available Screen Text and Screen Background colors.

Note: Experiment with various combinations. You can use the color picker to change colors quickly to improve readability.
To resize the window and remove the horizontal scroll bar:

a. On the Layout tab, in the Window Size settings, change the area’s Width and Height values until the Windows PowerShell console pane preview fits completely within the Window Preview area.

b. On the Layout tab, in the Screen Buffer Size settings, change the Width value to be the same as the Width value in the Windows Size settings.
Select OK. The console application should be ready for use.

Task 3: Start a shell transcript

In the Windows PowerShell console, enter the following command, and then press the Enter key:
```
 Start-Transcript C:\DayOne.txt
```
Note: You’ve now started a transcript of your Windows PowerShell session. It’ll save all the commands you enter and the command output to the text file until you run Stop‑Transcript or close the Windows PowerShell window. You can review the contents of the transcript at any time by opening C:\DayOne.txt.

Exercise 1 results

After completing this exercise, you’ll have opened and configured the Windows PowerShell console application and configured its appearance and layout.

Exercise 2: Configuring the Windows PowerShell ISE application

Task 1: Open the Windows PowerShell ISE application as Administrator

In the Windows PowerShell console, enter ise, and then press the Enter key.

Note: This method of opening the ISE will work correctly only when an administrator is running the console.
Close the ISE window.
Right-click the Windows PowerShell icon on the taskbar or activate its context menu, and then select Run ISE as Administrator. You should now be running Windows PowerShell ISE as Administrator.

Task 2: Customize the ISE’s appearance to use a single-pane view, hide the Command pane, and adjust the font size

To configure the ISE to use the single-pane view:

a. On the Windows PowerShell ISE toolbar, select the Show Script Pane Maximized option.

b. Select the Hide Script Pane up-arrow icon to display the console.

Note: Alternatively, you can press the Ctrl+R key combination.
Select the Show Command Add-on option to review the Commands pane, if it isn’t showing.
Select the Show Command Add-on option to hide the Commands pane.
Use the slider in the lower-right corner of the window to adjust the font size until you can review it comfortably.
Close the Windows PowerShell ISE and the Windows PowerShell windows.

In the console, enter the following command, and then press the Enter key:
```
Get-Help *branch*
```
Note: This will cause the help system to conduct a full-text search, because no commands use branch in their names.
