The last windows update batch contained update KB2553154 for office 32 bit.
This update breaks all COM and Active x controls in Excel (i.e. buttons, combo boxes etc.). Like many businesses we use Excel with these controls extensively and this update is crippling Excel for our users.
We have installed and uninstalled it on a number of machines both Windows 7 and Windows 8 and have proved this update is causing the issue.
PLEASE Microsoft withdraw or fix this update we can hardly go around all our pc's worldwide and manually uninstalling it.
A customer wondering if you test your updates before releasing them
