Excel 2013 High CPU Usage

Anonymous

We work on a product that uses Excel, we are now testing all aspects of Excel 2013. During these tests, we seem to have encountered a problem where excel suddenly causes high CPU usage by only drawing some shapes. We have been able to minimize the problem into the following few steps:

  • Open a new, clean workbook
  • Draw an oval, give it a material (right-click, choose “Format Shape”, click “Effects”, “3D Format”, “Material”. Choose any material.)
  • Duplicate the Shape four times, producing Oval2, 3, 4 and 5.
  • Group Oval2 and 3. Group Oval 4 and 5.
  • Press Alt-F10, in the selection window, hide the group containing Oval2 and 3.
  • Deselect everything (!) by clicking in an empty cell.

Now observe the task manager. On an I7 Windows 7 PC, Excel now runs 4 cores at around 50%. Also, OnTime functions are not being called anymore because of this rendering bug. Once you select any shape, or un-hide the hidden group, Excel becomes quiet once again. Also, the problem can be prevented from happening by removing the materials in the shapes.

This bug (?) seems to happen also on most of our more complicated applications, and it would take lots of work to re-design everything not to use materials. Can anyone confirm this problem, provide a workaround?

    Hi Gil,

    As previously posted, it seems that KB3114717 causes the issue which is why Microsoft withdrew the update as pointed out by Jkfweb

    To fix ours i did the following:

    Open Programs and Features from the control Panel

    Click on View Installed Updates

    Search for KB3114717

    Uninstall it

    Restart PC

    I then disallowed that update from GFI Languard and WSUS so it wouldn't automatically reinstall.

    Is there a similar update for Server 2008 ?

    Didn't find KB3114717 on any of my servers, update after February 9th.
