When I logged into my PC (Windows 10) tonight it said something like:
 
HI
 
Your system is being upgraded
 
We're excited about the new features
 
 
When it finished logging in, it showed a message that there were updates but my update history is blank.
 
I search a bit on the internet but I haven't found anything explaining this.
 
Anyone else get this or know what it means?

I didn't see this last night. Maybe this is the update: http://www.howtogeek.com/...indows-10-fall-update/
 
--Edit--
Oh, and this explains why the update history was empty: http://windows.microsoft.com/en-us/windows-10/windows-update-faq
 
It is called the November update but I did not get it until December. lol

They pulled the update (November update, Threshold 2, TH2, or version 1115) for a bit because of some issues with the privacy settings. Just got re-introduced recently.

Yeah 1511 (10586.17)
These sites will keep you on top of the latest Windows updates:
winbeta dot org
winsupersite dot com
blogs.windows dot com
 
There are more sites of course, but you can't go wrong with these few.
