How get the *original* cmd.exe console window title in PowerShell?

Question

As soon as PowerShell start run in a cmd.exe window the title of the window is changed to "Windows PowerShell"; however, the original title is stored in some place, because when PowerShell terminates, the original window title is recovered.

I spent some time reviewing the related documentation, but most examples show how get the current window title or change it using $host.ui.rawui.WindowTitle, but there is not a single example on getting the original cmd.exe window title (perhaps I just don't know what terms include in this search).

Is there any way to get the original console window title before PowerShell start run?

使用下一个代码段获取原始cmd控制台窗口标题：

@ECHO OFF
SETLOCAL EnableExtensions DisableDelayedExpansion

set "_myTitleTail= - %~0"
for /F "tokens=1,2,8,* delims=," %%G in ('
  tasklist /V /fo:csv ^| findstr /I /C:"%_myTitleTail%"
                                        ') do (
    set "_myTitleBatch=%%~J"
    set "_myCmdPIDno=%%~H"
)
call set "_myCmdTitle=%%_myTitleBatch:%_myTitleTail%=%%"
echo _myCmdPIDno=%_myCmdPIDno%
SETLOCAL EnableDelayedExpansion
  echo _myCmdTitle=!_myCmdTitle!
  rem powershell -NoExit -Command $Host.UI.RawUI.WindowTitle='"!_myCmdTitle!"'
ENDLOCAL

不幸的是，powershell -NoExit -Command $Host.UI.RawUI.WindowTitle='"!_myCmdTitle!"'（在上面的代码段中注释）解决方法仅适用于不包含powershell敏感字符（如撇号，双引号等）的简单标题。 例如，下一个组合适用于未注释的powershell行：

==> title some forgotten string
==> 39256629.bat

另一方面，在this (BTW, your current question inspired my answer there)

类似的情况下，我没有找到适当的转义

==> TITLE ...but my title is complex, that's why I can't find proper escaping!!!
==> 39256629.bat

Powershell会运行，但会一直抱怨绑定...点的意外令牌  或'撇号用于​​不同的逃避尝试......
