After install Cuda Toolkit the next Windows update borks display driver

Hi,

I successfully installed the CUDA Toolkit and got samples running. However following the next Windows update I just got a black screen. (This happened twice.) I was able to recover the situation by booting to safe mode and reverting the display driver to the previous version but after that the toolkit samples stop working

Details
GPU: Nvidia Geforce GT 750M
OS: Windows 8.1 (64-bit)
PC Model: Dell Inspiron 7537

Any help resolving this would be most welcome
