Windows 10 - We can't connect to Microsoft family at the moment...
Changes made to Microsoft Family children accounts on https://account.microsoft.com/family are not applied to Windows 10 PC.
After logging in to the PC with a parent's account I found following message in Settings > Accounts > Family and other users.
We can't connect to Microsoft family at the moment, so your family on this device might not be up to date.
Move U-Play game to another hard drive
There are few different ways you can move installed games from one hard drive to another without having to re-download them. The method I used involves manually moving the game folder to a new location and then creating NTFS Directory Junction to trick U-Play into thinking the game is still in its old location. I used this to move U-Play game Assassin's Creed Syndicate, but the same method should work with Steam, Origin and other games.
Combine individual media tracks into mp4 file
My MP4Box GUI is a tool I normally use to combine individual video and audio tracks (h264, aac, etc.) into a valid mp4 file. My MP4Box GUI is just a GUI wrapper for a free command line utility called MP4Box.
Usage is very simple - add all tracks into the main application window and click Mux button...
Extract individual tracks from .mkv file
Syntax is pretty simple:
mkvextract.exe tracks "D:\video.mkv" 1:"D:\track-1.aac"
D:\vide.mkv - Source file
1 - Track number ID
D:\track-1.aac - Destination file
mkvextract manual can be found here.
If you prefer to work with graphical interface, you can download a GUI add-on from here: https://sourceforge.net/projects/gmkvextractgui/
