UPDATE February 16, 2015: This update has been fixed and re-released under a new KB article number: KB2956149
Just yesterday we told you about a reported issue where KB2920732 broke PowerPoint 2013 running on Windows RT devices. Today, Microsoft is admitting there is a problem, and has publicly announced that the update has been removed.
In addition, the company is providing instructions on how to refresh the PC so that PowerPoint is back to a workable state.
Shortly after the release of KB2920732, Microsoft became aware of an issue affecting users of PowerPoint 2013 on Windows RT devices. We have removed KB2920732 from the Microsoft Download Center and Microsoft Update and will provide a new update as soon as a fix is available. In the meantime, impacted users can refresh their PC by following the directions here: https://support.microsoft.com/kb/2751424. This will refresh the device, while keeping your personal files and settings.
While February's Patch Tuesday has not been kind to Microsoft, it's been a lot less kind to the customers affected by the number of problems reported this month. We're still waiting to hear next steps for the font corruption issue affecting customers.
