Update: To fix this issue, uninstall the faulty update and reboot.
Online Support has today had calls from several customers with issues with Outlook. We are currently investigating a bug in Microsoft Windows Update. It affected all Windows 7/8/8.1 machines with Office 2010/2013.
The problem is with the software issued in yesterday’s update MS15-115. It was supposed to fix an issue with how Windows handles fonts, however it constantly crashes and restarts Outlook.
Microsoft told The Register: “We are looking into reports from some customers who are experiencing difficulties with Outlook after installing Windows KB 3097877. An immediate review is under way”.
How to Avoid being affected by the Microsoft Windows Update
David Yeldon, Technical Director at Online Support warns “[if you rebooted your PC or turned it off last night] your PC has probably already installed it, but it will only complete the installation when you reboot so it should be fine as long as you don’t reboot it.”
We are working on a way to prevent further machines from installing the faulty update. If you business has been badly affected by this, then contact us or call on 0208 232 1190 and we’ll do what we can to assist you.
