Windows Security Update (KB2753842) Causes OTF Fonts To Disappear

Hello,

I recently came across an issue where clients where experiencing missing fonts when viewing a PowerPoint project in presentation .  They could view the fonts correctly in editing mode no problem at all but when they went to presentation mode, they just disappeared.

This problem doesn't happen when you're using TrueType Fonts at all, just OpenType Fonts and if you were to drop the font size down to 12 or below, the OTF fonts show correctly in presentation mode.

The CAUSE is a Windows Security Update which addressed some security holes with OTF files.  There a quite a few WSUS servers which are set to install Security Updates by default, so I recommend you decline this update asap but only for client platforms as it's not likely you'll be using a client side app on a server.

The RESOLUTION.  Well to remove the update in Add/Remove but in order to remove the update in a silent manor different commands are required for XP and Windows Vista/7 workstations.  I put together a simple batch script which you can push out via Group Policy or run manually to remove the update from client workstations.  SEE BELOW.

Note: Once you have removed the update, you will need to reboot the workstation for the change to take effect.  I set this to run as a shutdown script in GP.

Also note:  apparently it's not just effecting PowerPoint. A lot of other application are reported to have issues such as Corel Draw.  I would expect quite a few companies that use custom OTF fonts will see issues from this update.

Hope this removal script helps.

  3. It depends on your environment. If you download updates straight from windows update, you can modify your settings so that you have to manually approve them. If you're in an environment where you don't have that control then it's a bit cloche but have a word with the system administrator or person who controls wsus anyway.
