Anyway to remove network introspection driver (vnetflt.sys) from Linux and windows VM other than reinstalling???
The only proper way I'm aware of is using the tools installer, which would require a reboot. You can, however, unload the vnetflt.sys module if it's causing issues until it can be properly removed.
In Windows guests, you'd use the following command from an administrative command prompt:
fltmc unload vnetflt.sys
Hope this helps,
