Pardon my ignorance as I only have a vague understanding of what minifilter drivers are. We have Windows 10 user workstations with a minifilter driver installed called PtcVfsd. When running fltmc from command line, some workstations report 2 instances of PtcVfsd, while others report 3 instances.

We are investigating an issue with the application related to this, and the workstations with 3 instances are experiencing the issue, while the others with 2 instances are not. I noticed this difference between the sets of data we had so I'm trying to find out what it could mean.
I have posed this question to the software vendor, but I'm also asking here for a second opinion.
