Environment

Microsoft Windows 10 Pro for Workstations
10.0.19042.685 (2009, 20H2)
WindowsTerminalPreview_1.5.3242.0_x64

Release version does it too.

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd]
Windows Terminal version (if applicable):

Any other software?

Steps to reproduce

Monitor WT's open "Process" handles while opening/closong new tabs or panes.

Expected behavior

WT will close its newly acquired handle to OpenConsole.exe

Actual behavior

WT does not close the handle

Using HANDLE64.EXE (Sysinternals, could also use their ProcessExplorer) ...

v:\> rem New Instance

v:\> handle64 -a -p windowsterminal.exe | findstr Process
  9DC: Process       OpenConsole.exe(10016)
  A04: Process       cmd.exe(3136)

v:\> rem Open a second tab

v:\> handle64 -a -p windowsterminal.exe | findstr Process
  9DC: Process       OpenConsole.exe(10016)
  A00: Process       OpenConsole.exe(9848)
  A04: Process       cmd.exe(3136)
  AC8: Process       cmd.exe(8480)

v:\> rem Close the newly opened tab

v:\> handle64 -a -p windowsterminal.exe | findstr Process
  9DC: Process       OpenConsole.exe(10016)
  A00: Process       <Non-existant Process>(9848)
  A04: Process       cmd.exe(3136)

How do you keep finding these things? Do you just routinely check out the handles for all the stuff you run on your machine?

I'm not complaining, but it is strange 😉

@vefatica commented on GitHub (Jan 5, 2021):

I'm generally concerned with performance, especially that of apps which have captured my fancy in some way. And I have several tools (some my own) for observing performance (and I enjoy using them).

In this case, I was trying to find differences between instances of WT which use little CPU when idling and ones which use a lot of CPU when idling (see #8625).
