Record an app session in Win10

(1/2) > >>

I discovered this cool trick in Win10 to record the activity of a window to a MP4 file. Nothing to buy, just a hidden option intended for gaming.

How to Record Video of an App in Windows 10

Mike Lobanovsky:
Yes, that's a very cool option and the quality and record speed are exceptionally high.

You seem to also have a discrete nVidia graphics card installed in there. Then, if you video driver is new enough and you have nVidia GeForce Experience installed, it can also provide you with an option to record the entire screen in full HD. Try to press Alt+Z and see if it brings up a HUD like this:

(Alt+F9 will start/stop screen capture even when the HUD is invisible, but use it to locate the Gallery folder where your mp4 videos are going to be stored)

Here is the info on the nVidia graphics chip in my laptop.

Hint: Don't try to record a VB6 IDE session. You system will go nuts.

I checked into the benefits of upgrading to Windows 10 Pro from Home which came with the laptop. I don't see any value for me upgrading and paying $99 to do so. One feature of Pro was to connect to a corporate network which would be nice but I can do that for free on my Linux laptop which also happens to be providing the Windows networking services for my new Windows 10 laptop. (WIFI only)

I wouldn't call it a particularly high-res capture... ???

Your config does include NVIDIA User Experience Driver components. So, do Alt+Z and Alt+F9 hotkeys work for you as they do for me? (the site wouldn't permit me to attach my ca. 40MB large full screen live HD capture here)
