I recently had to rebuild a PC recently and whilst a lot of my settings automatically came across (thanks OneDrive backup) my poor Windows Terminal did not do well with a profile migration. Setting up Windows in 2024 to work "nicely" with OH-MY-POSH (especially if your profile is a bit mangled by years of cruft and auto-sync'd rubbish) can be a bit more painful (particularly with some articles about Nerd font requirements, etc being scattered across various out-of-date articles) so I figured I'd document the process that worked for me!

First off, install your components:

• Install POSH itself:

  • winget install JanDeDobbeleer.OhMyPosh -s winget

• Install PSReadLine

  • Install-Module PsReadLine -Force

• Pick your font:

  • oh-my-posh font install

Install Terminal Icons (for icons in ls/dir commands:)

• Add Terminal Icons:

• Do the fix indicated here: https://gist.github.com/markwragg/6301bfcd56ce86c3de2bd7e2f09a8839 - i.e.

  • Download and install this version of Literation Mono Nerd Font which has been specifically fixed to be recognized as monospace on Windows:

    • https://github.com/haasosaurus/nerd-fonts/blob/regen-mono-font-fix/patched-fonts/LiberationMono/complete/Literation%20Mono%20Nerd%20Font%20Complete%20Mono%20Windows%20Compatible.ttf

  • Modify the registry to add this to the list of fonts for terminal apps (cmd, powershell etc.):

    • $key = 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont'

    • Set-ItemProperty -Path $key -Name '000' -Value 'LiberationMono NF'

  • Open PowerShell, right click the title bar > properties > Font > select your new font from the list.

  • Install and load Terminal-Icons:

    • Install-Module Terminal-Icons -Scope CurrentUser

    • Import-Module Terminal-Icons

In the end, my ($Profile) profile looks something like this;

oh-my-posh init pwsh | Invoke-Expression
oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH\paradox.omp.json" | Invoke-Expression
Set-TerminalIconsTheme

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