Start-Process -WorkingDirectory as administrator does not set location - powershell

Question

When I enter the command
Start-Process powershell -WorkingDirectory "D:\folder"
it opens new PowerShell window with D:\folder location set.
But when I enter the command
Start-Process powershell -WorkingDirectory "D:\folder" -Verb RunAs
it opens new PowerShell window with admin rights but with C:\Windows\system32 location set.
How can I open new PowerShell window with admin rights and my own location determined?

Answer 1

I also had the same problem and solved it with this command:
Start-Process powershell.exe -verb runAs -ArgumentList '-NoExit', '-Command', 'cd D:\folder'
Once you run the above command, Windows will launch with admin authority and the specified directory.

Answer 2

Here's another example which can be used for opening CMD from PowerShell as an administrator into the current folder:
Start-Process cmd -ArgumentList ("/k cd {0}" -f (Get-Location).path) -Verb RunAs
if used within a script you can use
Start-Process cmd -ArgumentList ("/k cd {0}" -f $PSScriptRoot) -Verb RunAs
If you want to open a new elevated PowerShell session from the current one which is not elevated you can use:
Start-Process powershell.exe -ArgumentList ("-NoExit",("cd {0}" -f (Get-Location).path)) -Verb RunAs
or
Start-Process powershell.exe -ArgumentList ("-NoExit",("cd {0}" -f $PSScriptRoot)) -Verb RunAs
when used inside scripts

Answer 3

When using Start-Process with -Verb RunAs, a -WorkingDirectory argument is honored if the target executable is a .NET executable; examples:
pwsh.exe (the PowerShell (Core) CLI) does honor it.
cmd.exe and, curiously, powershell.exe (the Windows PowerShell CLI) do not, and invariably use C:\Windows\System32.
The problem exists at the level of the .NET API that PowerShell uses behind the scenes (see System.Diagnostics.ProcessStartInfo), as of this writing (.NET 6.0.0-preview.4.21253.7).
Unless you know that you're invoking a .NET executable, a workaround that changes to the desired working folder in the new process is therefore required; to offer a more robust alternative to ふゆな's helpful answer:
$dir = $PWD.ProviderPath # use the current dir.
Start-Process -Verb RunAs powershell.exe #"
-noexit -c Set-Location -LiteralPath "$dir"
"#
The embedded "..." quoting around $dir ensures that paths with spaces are also handled correctly. (To use the current directory without an intermediate variable, replace "dir" with "$($PWD.ProviderPath)".
Using a here-string (#"<newline>...<newline>"#) isn't strictly necessary, but simplifies the embedded quoting; with a regular expandable string ("..."), the embedded " must be escaped as `" (or "").
Using $PWD's .ProviderPath property ensures that a file-system-native path is used (based on drive letters also seen in cmd.exe, for instance), given that the calling session's current location may be based on a PowerShell-only drive (see New-PSDrive) that the elevated process may not have defined (at all or not based on the same root location).
Caveat: If the native path is on a mapped network drive, this won't work, because elevated processes do not see the same drive mappings; in that event, pass the underlying UNC path.
Workaround for launching a GUI application elevated from a given working directory:
Since changing to the working directory must happen in the new, elevated process, a helper shell process is needed to perform this operation, which is best done via cmd.exe (for better performance):
$exeToLaunch = 'Notepad.exe' # may include arguments
$dir = $PWD.ProviderPath # use the current dir.
Start-Process -Verb RunAs -WindowStyle Hidden cmd.exe #"
/c cd "$dir" & $exeToLaunch
"#

Answer 4

Once you run Powershell as administrator;
user the push-location command like so:
Push-Location -Path C:\
or put it into your script and run the script from the elevated Powershell prompt.

Answer 5

I just ran your code example and it opened correctly for me at the WorkingDirectory location. Ensure the directory exists before you run the command. I tested against a drive on C and secondary drive as well and both worked.
