I know KB2919355 is a mandatory update for all Win 8.1 users.
What I want to know is..... how come I get to install it twice ?
First I installed it was on Aril 3rd when I installed 5 Win 8.1.1 updates.
Yesterday, It showed up on my Windows Update notification. So, I installed it again.

Note :There is a slight difference in the name of the same KB.

Checking mine, I only see it installed once and that was on the 8th of this month. I looked all the way back through April....nothing. I know you could grab it early from MS download server or what ever it's called. There were 4 of them to grab. Did you get it that way?

Actually there were 6 updates.
KB2919422 we already had installed some time ago.
KB2939087 is not required
So only 4 updates were installed on April 3rd. ( my screenshot).

Just wonder if the 2 KB2919355 are different. If not, why the system installed a duplicate ?

You got me...I have no clue.

On April 3rd, I saved the Win 8.1.1 updates into my Downloads folder.
At the time I downloaded the updates, they were all called Windows 8.1

Those look like they came from the MS server download site and not through windows update. I did the same thing, saved them to my downloads folder as well...but 2 of them wouldn't install so I just gave up, uninstalled them and deleted them from the downloads folder and waited till the 8th to install from windows update.

Guessing here; if that's the case, then when the updates came through the "windows update" they may very well show up as being installed twice and with a different name format.
