In the past, the Google Hangouts desktop app on Windows would integrate with the system “tray” (actually the notification area) and show you missed chats and calls.
The [Wayback/Archive] Google Chat desktop app does not. It shows missed messages only as a number on the taskbar icon. Even worse: when you close the Window, the taskbar application icon does not show that number any more.
The odd thing is that the Google Duo desktop app does stay active and shows a notification popup on incoming calls. The Google Chat desktop app does not.
So I wanted to restart the Google Chat desktop app automatically when the Window was closed. But there is a catch:

Since every now and then, like testing software developed with older tools, you need to run older software.
This always works: [Wayback /Archive] Deploy .NET Framework 3.5 by using Deployment Image Servicing and Management (DISM) | Microsoft Learn
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All
Use /All to enable all parent features of the specified feature.
(The /All is needed because software requiring .NET Framework 3.5 also require the parent features).
Notes:
- Tested on Windows 10 and Windows 11 in 2022.
- It can take a really long time (more than just a few minutes!) even on fast connections.
- Installing through Chocolatey with `choco install
dotnet3.5 fails on Windows 11 (have not tried on Windows 10) with the classical red on black PowerShell default error theme*:
ERROR: The term 'wmic' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
The install of DotNet3.5 was NOT successful.
Error while running 'C:\ProgramData\chocolatey\lib\DotNet3.5\Tools\ChocolateyInstall.ps1'.

Simple (but fully working) code for NPLogonNotify(). The function obtains logon data, including cleartext password.
[Wayback/Archive] PSBits/PasswordStealing/NPPSpy at master · gtworek/PSBits has been used in the wild since about 2022 (the code is from 2020).
The code is a ~100 line C file resulting in a DLL exporting the NPGetCaps() and NPLogonNotify() functions.
Background/related:

Note that the below methods likely will cause security warnings if a Windows machine has been properly configured, but in most cases at least one of them works.
- using cURL (Widows 10 and up)
curl --url https://speed.hetzner.de/100MB.bin --output %TEMP%\100MB.bin
- using [Wayback/Archive]
certutil | Microsoft Docs (at least Windows 7 and up; needs UAC elevation)
certutil.exe -urlcache -split -f https://speed.hetzner.de/100MB.bin %TEMP%\100MB.bin
- using PowerShell (at least Windows Vista and up)
powershell.exe -Command (New-Object System.Net.WebClient).DownloadFile('https://speed.hetzner.de/100MB.bin','%TEMP%\100MB.bin')
I think it works for all versions of curl, certutil, and PowerShell though I did not have anything older than up-to-date Windows 7 (having PowerShell version 3) and recent to test on.

Reminder to check-out of the 2015 issue mentioned in the tweets below has been had any progress.
At the time of tweeting, choco has no notion of [Wayback/Archive] status.chocolatey.org which would be very helpful to point to in case of errors on time-outs on chocolatey server calls especially if it could interrogate and inform of maintenance windows and outages when things fail on the client side.

Many companies have hardly any idea how many scripts are being used by their people to get the chores of day to day work done.
