Having a screen recording to document an issue is always helpful when trying to explain the issue to someone else.
I also use a recording in combination with packet captures so I can exactly determine when I do something and which packet to reference.
The challenge in the real world is that many environments do not allow you do install third party, non-approved applications. As long as the information isnt sensitive and I typically deleted the video file after I document what was done and its corresponding packet number.
When this first happened to me, I resorted to using my smartphone to record the screen. After a while I started poking around to see what other options I can find. With Windows 10, you can use the Game Bar application, but I find that most places strip that out.
A few weeks ago, I stumbled across the screen recording function within PowerPoint. Most large corporations use PowerPoint, so this was awesome.
In the following video, you will see how I use PowerPoint screen recording, pings and Wireshark when troubleshooting or performing a baseline.
