If you check the versions of the files you can see that it’s some kind of update:
Hold Em Poker Game
New version: 6.0.6000.17034
Previous version: 6.0.6000.17015
But the BitLocker secure key backup utility have the same version, 6.0.6000.16442, but have a different size on the file 1.11 Mb (updated) vs 1.10 Mb (previous).
As of now I have no idea why these Extras are updated, first release of these two were january 30th, or if they contain anything new and there are still no information from Microsoft on these updates.
