PowerShell allows its own current path to differ from what Windows thinks is the current path:
[IO.Path]::GetFullPath('.') cd $env:windir Get-Location [IO.Path]::GetFullPath('.')
So, whenever you want to use one of the .NET Framework methods from IO.Path, you need to sync the current location like this:
[IO.Path]::GetFullPath('.') cd $env:windir [IO.Directory]::SetCurrentDirectory((Get-Location -PSProvider FileSystem).ProviderPath) Get-Location [IO.Path]::GetFullPath('.')
