SYMPTOM
The RAM usage keeps raising without any reason. A reboot solves the problem, but after a couple of days the memory usage is growing again.
CAUSE
The service “SynTPEnh Caller Service” is responsible for this behaviour.
SOLUTION
Remove the Synaptics pointing device driver from your system.
The driver is not required for your workstation.
A major Windows update (like 1909) may reinstall this driver onto your system again!
