Assume that you install Microsoft Office 2013 Service Pack 1 (SP1) or the November, 2013 update for Lync 2013 on a computer. The computer uses accelerated H.264 video encoding based on Intel chipsets that have HD Graphics 2000 or a later version. Then, you make a video call or you rest the mouse pointer on a video icon in Lync 2013. In this situation, at least 60 megabytes (MB) of memory will leak in Lync 2013. The memory leak will persist until you restart Lync 2013.
This issue occurs because the Hardware Media Foundation Transform (HMFT)-related objects are not freed in each capability query. Additionally, Lync 2013 creates an encoder instance that starts another query when you rest the mouse pointer on a video icon.
To resolve this issue, install the following cumulative update:
