/savecred
allows the account holder to run any command as you. Mightn't matter in your case but keep it in mind. It's only in Windows as a compatability thing. It will disappear in the future.
If it's a command prompt start cmd and use the title
command then start your program.
C:\Users\User>title /?
Sets the window title for the command prompt window.
TITLE [string]
string Specifies the title for the command prompt window.
If a GUI program this sample VB6 code changes titles. You can use vb.net to make a program of it.
Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Public Declare Function SetWindowText Lib "user32" Alias "SetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String) As Long
Sub Main()
On Error Resume Next
hwindows = FindWindow(vbNullString, "Microsoft Works Calendar")
Ret = SetWindowText(hwindows, "Calandar")
End Sub

This is similar but is about manipulating Windows appactivate between multiple internet explorer instances (PS: On Win 7 and later sendmail is a reserved name so must be changed).
.NET framework (which powershell uses) doesn't have Windows commands in it, manipulating other program's windows is not in the .NET philosophy. This is probably the only area where .NET doesn't reflect the Window's API. .NET programs can manipulate their own windows through their forms object.
