KB2670838 is a Prerequisite Update for IE10. If it's not installed, IE10 will "drive-by" install it. Similarly, uninstalling IE10 would automatically (and silently) uninstall KB2670838 if all were well with your computer.
KB 2670838 - The EVIL UPDATE
Microsoft:
Why don't you fix the errors caused by KB 2670838 instead of having my computer re-install it as part of IE 10 without giving me any warning that it was going to do that?
This update has two effects on my system*; 1. For whatever reason, it turns the lower taskbar turquoise, 2. Explorer 9 or 10 and Chrome 25 get a 60 delay in information typed into them with internet speeds reminiscent of dial-up, while Firefox 19 ceases to function at all; The internet becomes essentially non-usable.
I wasted an entire day on this two weeks ago including an hour on the phone with one of your technicians when it was first installed. He had no idea what the problem was and I eventually gave up and uninstalled it. My problems ceased immediately upon its removal.
I had to go to an internet forum to learn that many people had these problems and how to set my updates to not automatically be installed. That proved to be no help as when installing IE10 this EVIL UPDATE (KB 2670838) just re-appeared again with no notice in your description that this might happen. Now I guess I will never install an update again since you provide no clues as to what it could do.
* My system info:
HP Envy, Windows 7 Home Premium, two screens attached using an HP usb notebook port replicator. Buy the way, this HP port replicator is a piece of garbage that has to be rebooted (the replicator - not the PC) as it freezes once or twice a day. But I thinks that's on HP - not you.

2013-04-26T19:06:33+00:00 @AXELRMSFT (AKA AskIE blog alias):
When IE9 Final & earlier became available via Windows Update, Microsoft offered US & CA residents free phone support for install and uninstall issues. Consumers were also eligible for the support if an IE-related issue caused computers to crash or if IE did not let you browse all sites. Residents of other areas were offered similar, no-charge support.
Will Microsoft be offering this for IE10, too, and if so, when?
Thank you.
PS: Regards to Mark Freetham & Jeff Pape.

2013-04-26T14:34:02+00:00 Also, to give you a better idea, this is a corporate network, and this particular update is causing issues with IE9 on the company intranet page. The update shows a successful install date of 2/27/13, but when i check the event logs, I see all other updates listed as installed, except for this particular update.
All, the http://support.microsoft.com/kb/2670838 is a windows update and it did cause a lot of different application issues. I suggest to review the article and see if any of your HW or other applications that uses the Windows Graphics subsystem (directX, etc) needs to be updated.
For your internal IT Environment scenario, you want to report all issues to your System Administrator so, they can investigate your problem. All applications that use windows graphics subsystem could have been impacted. Start, by looking at your hard ware and software drivers.

This is a Consumer-specific forum. Please contact your SysAdmin or IT Department for further assistance.
If you are the SysAdmin/IT Department, you will find appropriate support in the Win7 IT Pro forums: http://social.technet.microsoft.com/Forums/en-US/category/w7itpro
TIP: Ignore Update History; if an update isn't listed in Installed Updates, it's not installed.
