+You can use the `oh-my-posh debug` functionality to see where Oh My Posh spends its time.
 In case there's no clear culprit (timings indicate everything's OK), chances are some modules are the culprit.
 We bootstrap a few PowerShell modules to maximise compatibility, but sometimes these can introduce unwanted side-effects.
 
 The modules we support are:
 
 - posh-git
-- Az.Accounts
-
-Especially the latter can slow things down so the first thing to do is disable that one:
-
-```powershell
-$env:AZ_ENABLED=$false
-```

-Once added, reload your profile for the changes to take effect.

-```powershell
-. $PROFILE
