CPU usage increases largely when you have multiple animated emoticons in conversations in Skype for Business

Applies to: Skype for Business

This issue occurs after you apply the April 14, 2015 update for Microsoft Skype for Business.

  • Turning off emoticon animation in the Option dialog box cannot prevent CPU draining. 
  • CPU usage will not decrease until you close the conversation windows.


To resolve this issue, install the May 12, 2015, security update for Skype for Business.
