I recently applied updates via Lenovo System Update and now the touch pad stops detecting multi-finger touches shortly after startup. It works for a few minutes, then I guess something either gets loaded or crashes and the touchpad stops detecting multiple fingers.
Therefore, two finger scrolling and two finger pinch stop working.
This was working fine about a month ago.
Synaptics Pointing Device driver: 22.214.171.124
Synaptics SMBus Driver: 126.96.36.199
Windows 8.1 Enterprise - 64-bit Version 6.3.9600 Build 9600
T550 - Model 20CK000GUS
I tried to re-install the UltraNav driver and thatdidn't resolve the issue.

Oops sorry I gave you the wrong link:
It does say Windows 10 and it does say L450,T450, T450s, but it installs fine on my Windows 7 on W520.
The driver for this one is dated 2018-01-16. Your driver is dated recently, but it was due to a security issue that needed to be fixed.
