maybe in the past i used Viscosity to test functionality, i do not remember.
Now if i install OpenVpn ... viscosity tap adapter appear in the network connections for a moment...

Drivers detail:
Published Name: oem20.inf
Original Name: visctap0901.inf
Provider Name: SparkLabs VPN
Class Name: Network Adapters
Class GUID: {4d36e972-e325-11ce-bfc1-08002be10318}
Driver Version: 05/09/2016
Signer Name: SparkLabs Pty Ltd

I did: pnputil -f -d oem20.inf, oem20.inf was deleted, visctap0901.inf* was deleted from DriverPackages..., i deleted visctap0901.sys from window/system32/drivers folder manualy also...

Rebooted... driver is installed again :(

In the windows registry i found that value in HKEY_LOCAL_MACHINE\DRIVERS\DriverDatabase\DriverPackages\visctap0901.inf_amd64_30d1404d9c811413

OemPath => c:\windows\temp .... ???? Driver is installing from temp directory on reboot ? Which process copied vistacp0901.inf to temp and from which location ??

How to remove this driver forever from my PC ?

Installing and uninstalling Viscosity not helps... (installation creates new driver)...

Sorry for my bad english :-)

Hi neradp,

This certainly isn't something intended, nothing Viscosity related would be copying the driver to Windows temp. The best way to force an uninstall is to install an adapter, then from Device Manager, uninstall the driver and tick to the option to delete the device driver. If this is not working, I'm afraid something else is restoring the driver not related to Viscosity.
