Does Microsoft have anything like camstudio or camtasia?

I use Camtasia to record screen sessions and interactions at work.  Is there anything that Microsoft has that records video of screen interactions?

yes,

Microsoft Expression Encoder 4 with Service Pack 2 (SP2)
http://www.microsoft.com/en-us/download/details.aspx?id=27870

there is a utility included.

Is it in productsweb?

If you do not need a continuous video and just want to document steps you can use Screen Recorder (press your windows key and type in Screen Recorder)
