Microsoft updates.

[#1]

After more searching it looks like there is not "Update 1" text shown after the update. I have found the update 2919355 apparently the correct update without any reference to update 1 in it's title.

Hi Pod,
I had a similar problem - when just after 7pm it did an update but was only small, about 80M -
but look for this in your list of updates.
Update for Windows 8.1 for x64-based Systems (KB2933809)
The easy way to see if you have the update is on the Start screen - look for the search icon top right hand corner
TBH - im not surprised a few people had trouble - the servers must have been ery heavily loaded. We should have left it a day or so but I was just curious to see what the changes were Rather underwhelmed !
