Windows 10: TAP drivers create a new net device on each boot - how to uninstall ?

    TAP drivers create a new net device on each boot - how to uninstall ?

    Hi guys,

    I'm having a hard time with the TAP drivers coming with openvpn and virtual box. I noticed recently that upon each boot, new, unwanted devices are created automatically. So I had like ~26 virtual network card, each numbered incrementally. I removed them, but they keep coming back. 2 at each boot, since I have two version of these drivers, namely 'tap0901.sys' ( and 'tapoas.sys' ( I think one is from the virtual box install and the other one from openvpn. So every time they're loaded by the operating system, it's like they can't figure out that on device is created already, and keep adding some.

    Here's the full history:
    - Bought new computer with Windows 8.1 a year ago
    - Installed virtual box, no problem at all. I did not check devices every day but 100% sure it was fine.
    - Upgraded to Windows 10, didn't check the device section..
    - Installed openvpn
    - Uninstalled it the same day. So maybe 2 or 3 reboot occured.
    - Checked devices to see if everything was gone. Surprise ! It wasn't gone at all but replicated like rabbits !

    So I'm unsure if it's openvpn or Windows 10 upgrade that triggered the problem. Because the number of virtual device I saw the first time seemed to match the few number of boot I did Under Windows 10...

    Here's what I tried so far:
    - using the TAP utilities to delete all... OK but no luck at next boot...
    - basic removal ( right click properties / configure / uninstall (remove driver checked) )... no luck
    - basic removal + delete drivers file in safe mode... no luck
    - basic removal + delete drivers + disable automatic drivers luck
    - used the autoruns utility to disable the faulty drivers... no luck
    - used Pnputil.exe -d on the incriminated oem#.inf files ... no luck
    - there are some entries in the registry but I get an access permission error on these ones, even in safe mode

    What the f... is bringing these files back?
    Some other people have the same problem here.
    EDIT : The same exact problem described here (in spanish but screenshot are explicit).

    So do you guys have any way of deleting these drivers ?
