Chocolatey is a package manager in Windows. It’s pretty neat.

When I was installing Chocolatey, I ran into the following warning—tab completion did not work properly.

WARNING: Not setting tab completion: Profile file does not exist at
'C:\Users\*username*
\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1'.

These are the proper steps I have done to install Chocolatey without the ‘tab completion’ warning.

This is a note for myself. It might not work, or it might. I’m not responsible for anything.

1. This is to create a PowerShell profile for your Windows user.
   Enter the following in a PowerShell session.

   if (!(Test-Path -Path $PROFILE)) {
    New-Item -ItemType File -Path $PROFILE -Force
   }

2. Run notepad $profile in the same PowerShell session.
   This will open the Windows user’s profile file in Notepad.
   Append the following code to the profile file and save it:

   # Chocolatey profile
   $ChocolateyProfile = "$env:ChocolateyInstall\helpers\chocolateyProfile.psm1"
   if (Test-Path($ChocolateyProfile)) {
    Import-Module "$ChocolateyProfile"
   }

3. Run another PowerShell session as administrator
   Run Get-ExecutionPolicy and you will likely get Restricted.
   If so, run Set-ExecutionPolicy RemoteSigned.
4. Install Chocolatey using the following command:

   Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

5. You should not have seen the ‘tab completion’ warning while you were installing Chocolately.
