What You Are Seeing?

Hitting tab after typing choco only shows filenames

What is Expected?

Choco commands like install, upgrade, etc. should be shown

How Did You Get This To Happen?

1. Make sure PowerShell profile contains the following snippet

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

2. Upgrade PowerShell to 7.4.0
3. Type choco and hit tab

Output Log

(N/A - not sure how to get logs for tab completion)

Additional Context

The cause is that Chocolatey only defines TabExpansion function to enable completions, while that function is no longer used by PowerShell 7.4 [1]. A solution might be adding TabExpansion2 function (supported since PowerShell 3) besides the existing TabExpansion function, so that all users with PowerShell 2 ~ 7.4 can have Chocolatey tab completions.

As a side note, if TabExpansion2 is added, #2255 will likely be solved as well.
