Hi All,

Ever wanted to detect if your PowerShell Script is running in a WindowsTerminal Session?

As you can see, the default Font is a bit bigger than in the other PowerShell Windows

Here is some code to detect that

if ($env:WT_SESSION) {
Write-Host "Windows Terminal detected"
} else {
Write-Host "Windows Terminal not detected"
}

Windows Terminal

PowerShell 5

PowerShell 7

PowerShell ISE
