"thinkpad video features" update fails and breaks machine. Anyone else got this?

Question

The update is "thinkpad video features [...Quadro 1000M/2000M Optimus] for Windows 7 64" version 8.17.12.7593/8.15.10.2538.
It failed (gave an error message during install allong the lines of "update failed").
After this, I could not play any Direct-X games. 
It also killed my color-munki profiler, so the colours are now completely off. I resinstalled the color-munki, reprofiled and im more or less back to where I started, but without the update.
Does anyone know one rolls back, or re-applies an upate?  The failed update is no-longer appearing in the new upate list.
I was hoping the update would fix some of the external monitor problems, where it randomly will not expand to a second monitor, or the internal monitors reoslution gets stuck at some low res for no apparent reason, wakeup "loses" the monitor and switches back to internal only etc.

I've had that software installed for a long time (it was released back in November), and it is trouble-free.
If you have only recently attempted to install it, go to 'Control Panel', select 'System', at the upper left corner of the screen click on 'System Protection', then roll back the system state to a date and time prior to when you installed the driver.
In the future, I recommend that you use ONLY the Lenovo System Update application to fetch and install updates.  You have created too many problems for yourself over the past couple of months trying to install drivers on your own.
