Following the recent Lync 2013 CU2 update release, this evening I thought id update my Lync 2013 client with all the new CU2 goodness. Problem is even though the update was successful I saw some of my icons become weirdlike and the wrong size, and were more in line with windows 3.1 than office 2013.
On further investigation and after a full removal of the Lync client and the patch and reinstall, I thought it would be good to update my win8 machines windows patching. On running the windows update module it came back with an update for Office and also a update for Windows 8. (the one of interest is the Office update KB article stated in the update is http://support.microsoft.com/kb/2817489). when you read the KB the second item for the fix is the icons, therefore it became a no brainer to run these in. <sorry im unable to screengrab the updating> (expect a reboot after the update)!
So following the reboot the icons looked good again.
Simple fix in the end
