Windows Update KB3013455 breaks Font Smoothing on Windows XP, Server 2003R2 and 2008

Hello Folks,

if you are using Windows XP as VDI or have old Terminal Server’s (incl. Citrix solutions) running Microsoft Windows Server 2003R2 or 2008 (32-Bit) you should not deploy KB3013455 which was released during the last Microsoft Patch Day.

The Update will cause a general font smoothing issue with a bunch of fonts and the users will/can get a much lower user experience if working with a lot of text content.

There is currently no work around for this issue, Windows Server 2008R2/2012(R2) and Windows 7/8(.1) do not show any issue once the update is applied.

The issue is already confirmed by Microsoft, read also here: MS15-010

The MS15-010 article currently doesn’t mention Windows XP (or Vista) but i was able to reproduce it also with a Windows XP 32-Bit VM.

Cheers
Michael

P.S.: Some Users also reporting issues with Windows Vista 32 Bit but i believe this is less important for VDI environments.
