Some users who upgraded to Mathematica 9 for Windows have reported 
encountering blue-screen system crashes.  The system crashes seem to be 
caused by a Windows bug in handling how we update fonts, and can
potentially happen even when not running Mathematica (for example, 
opening the Fonts control panel might cause a blue screen).  The issue 
only affects Windows machines which had older versions of Mathematica 

The issue is rare and was not found during extensive internal and 
external prerelease testing.  However, we're taking the issue very 
seriously, and we recommend that you don't install Mathematica 9 for 
Windows until we can provide you with a patched installer, which should 
be available for download from in the next few 

If you have already installed Mathematica 9 for Windows and have not 
encountered this issue there is nothing you need to do.

If you have installed Mathematica 9 for Windows and have encountered the 
issue, you can find a solution for the problem here:

Or, feel free to contact Technical Support and they can help you walk 
through deploying the fix.

We apologize for any inconvenience this may cause you.
