Unwanted TAP-Windows Adapter V9 and TAP-Win32 Adapter OAS drivers installing RRS feed

  • Question

  • After upgrading to Windows 8.1, things were working fine until about 100+ updates came through... and now these TAP-Windows Adapter V9 and TAP-Win32 Adapter OAS drivers are installing over and over again. I uninstall the drivers and they come back, I disable them, and they re-enable themselves. I have looked up answers to this issue, and I do not use a VPN...so none of that applies to me.

    The unfortunate part is that I get constant interruptions with my internet and don't even want to touch my laptop hardly anymore because of this...but I need to because I am trying to start a business and get back into school. The only way I can get the internet to work again is to disable the drivers, and troubleshoot my wireless adapter. It renews the wireless adapter, the internet works for anywhere between one minute to an hour before I have to troubleshoot again.

    HELP?? How to I block those drivers? There needs to be a Microsoft Removal Tool and a major update...

    I tried to add a screenshot, but it took so long to verify me that I had already deleted it after 4 days.

  • Ok it's more than a week now and I'm not seeing any Tap-adapter, hopefully it will work for you guys too: untick all in IPv4 and IPv6, if another Tap appear, uninstall them both from device manager.

  • Upon further inspection, I found that the only two items that were installed on my Wi-Fi connection was Internet Protocol Version 6 (TCP/IPv6) and Internet Protocol Version 4 (TCP/IPv6) ... still looking for IPv5. JK. :D

    I went through removing all the TAP drivers, and then I used cmd.exe ran as an administrator:
    netsh winsock reset
    netsh winsock reset catalog
    netsh int ip reset c:\resetlog.txt
    ipconfig /flushdns

    After that, I installed the following to my Wi-Fi connection:
    Client for Microsoft Networks
    QoS Packet Scheduler
    File and Printer Sharing for Microsoft Networks
    Link-Layer Topology Discovery Responder
    Link-Layer Topology Discovery Mapper I/O Driver

    I have restarted my computer, and seemingly things are working better... I certainly hope it stays this way. If it doesn't keep the TAP drivers away, does anyone have a solution I have not tried?

    Please, and thank you? :)

  • Finally someone who have the same problem as me. But I have some bad news, in my case, I'm seeing unknown access to many accounts of my, even some failed money transaction from my paypal (thank god I have not connected my credit card). So there's a high chance that someone connected to your laptop and is stealin infomation from you. Best check all your accounts, especially anything to do with identity or money.

    As to getting rid of this annoying Tap Adapter V9 connection, I've tried many things, even deleting the driver from my laptop WINDOWS\System32\DRIVERS\tap0901.sys to no avail, it just keep appearing. Now I just open the adapter properties and untick all IPv4, IPv6... and for now it seems to work, no connection even when I enable the adapter, will get back to you if anything happens. I hope you will share your methods with me if you can remove this permanently.

    Friday, September 12, 2014 8:11 AM
  • Well I've got no unknown accesses to any of my accounts, and don't really have anything for anyone to get into. Plus I'm running AVG and Spybot: Search and Destroy. Nothing had been detected.

    But nevertheless, if someone is trying to access my computer... it's their loss since I can't access the internet when that adapter is installed and enabled. This morning one of the TAP-Windows Adapter V9 drivers had installed itself... is there absolutely no one at Microsoft that knows what's going on here? This is absolutely ridiculous.

    I've decided to delete WINDOWS\System32\DRIVERS\tap0901.sys and replace it with a blank file to try to immunize it somehow. I will make updates about if it works or not.

  • My method failed, a new adapter appears name Tap-Windows Adapter V9 #2 appear under the original one, so I just uninstall both driver from device manager. It'll be back but I just don't want to deal with 2+ of them. How are you doing on your end?
    Saturday, September 13, 2014 3:43 AM
  • It seems to work till now. I hope it stays this ways. If you get any update, please share. Thanks.
    Sunday, September 14, 2014 7:39 AM
  • Well, for a while this worked... I have been uninstalling things I don't need and hoping one of them could be the culprit, and to no avail. The driver just now reinstalled itself and was sitting there like a frog on a log waiting for a fly. Grrr. I think I might just uninstall and go back to Windows 7 or even XP... at least I didn't have problems like I do with Windows 8. This is truly ridiculous, and still no one from Microsoft has been here for help or commentary. Not sure why I expected any more.

  • Funny thing, adter I remove the 2 Tap adapters, nothing seems to be popping up, I don't know if it have anything to do with Microsoft update. It's been a few days now, still a liitle early to keep my hope up but I thought I'd keep you guys updated about it.

    BTW, AliAwan, are you having the same problem as us?

    Tuesday, September 16, 2014 9:04 PM
  • Well, I've uninstalled anything and everything that could have possibly caused this...and then just now it came back again. I personally give up. lol. At least until Microsoft comes up with something to disable it...

    I do have to ask though, what do you guys use to connect to the internet...maybe that's where the problem is? I have Comcast ISP with their built-in wireless. I haven't connected to anything but a wireless connection with this computer.

    Tuesday, September 16, 2014 10:16 PM
  • Sorry, I don't live in the States, my ISP is a military owned company in my country. So I doubt it's the ISP.

    As to method of connection, my laptop is used mixed both with wired and wireless, and I've seen the thing pop up both times, so I'm not sure, could be me switching wired and wireless without checking.

    On a side note, still haven't seen it pop up, been a few days now. Maybe the last Microsoft update fixed it?

  • I do what this says, I think I have uninstalled the driver 20 times now, It just keeps comming back. so how can you have this as a sulution, you shouldn't have to keep uninstalling it everytime it shows up, then it's no way better then a spam in a mailbox.
    Monday, November 10, 2014 5:01 PM
  • It's not a solution. I untick all in IPv4 and IPv6 and disable all tap-adapters in ncpa.cpl. Then i uninstall all tap-adapters in devmgmt.msc. Over time (about a week or month) they coming back, it's like clean spam folder in my e-mail box.

    One time i've used OpenVPN client, but it was removed a long time ago.

    Is deleting WINDOWS\System32\DRIVERS\tap0901.sys and replacing it with a blank file helpful? Somebody testing it or this file come back again?

    P.S. sorry for my english.

  • Hi, I have the same problem....I saw this VPN devises and catch someone copying a file from my PC(I was working normally and next second a little window copying a file from my docs...was just a second)

    I'm trying this.... delete any file "tap0901", on safe mode also delete the folder named "vpnplugins" is in "Windows folder"(I'm not sure about this but since I'm not using VPN not need it(better safe than worry)).

    I ran a search on all my PC looking for "tap0901" and I found a folder on "C:\Windows\System32\DriverStore\FileRepository" with 4 or 5 files related to "tap0901"....Delete.

    THE F*** TAP-Windows Adapter V9 is GONE!

    NOTE: Norton Scan didn't see any problem but there is a big one. Disable and uninstall the devise doesn't work  you need to delete any little shit related to "tap0901".

    NOTE 2: When U make the Search for "tap0901" files be sure than check the Advance options : File Contents, System Files, Zipped (Compressed) folders... on view also check "hidden items"

  • I actually had the same problem, I'm looking for a solution since 2014 september.
    And now 4 month later, maybe has come a genius !

    Because since september, I've deleted around 40 "local network connection", then I give up. This shit is just like rabbits, they grow faster and faster. I currently have 66 unwanted "local network connection" (connexion au réseau local, because I'm french), with about a half of "TAP Windows adapter V9" and the other half "TAP Win32 Adapter OAS".

    Ok, so I deleted both "tap0901 and "tapoas" related files, and I hope it will work.

    If any of you wants free connections, I've a lot to give :)

    (If this works, I will send you chocolate !)

  • Hi, I don't think its gone dude please check your device manager (press view show hidden devices). I think their will be an unknown adapter in your network subtree.

    Please Reply Regards HRida.

  • For now i have the solution, i guess...

    Start windows in safe mode --> than delete the tap adapters from device manager --> show hidden files, go to this computer --> Search for *tap0901* (1 .sys file 2 dll files) delete these 3 files --> use regedit --> local machine -->system --> currentcontrolset --> services --> delete the whole folder tap0901

    This should do the job

    for the OAS adapter you need to delete your vpn client if using one....

  • @Bungelaar

    I have never installed a VPN client (I thought). 

    I tried your solution, but while researching for "tap0901" and "tapoas" in regedit, I found these two key :

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\PnpLockdownFiles\%SystemRoot%/System32/drivers/tapoas.sys

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\PnpLockdownFiles\%SystemRoot%/System32/drivers/tap0901.sys

    As they were protected, I modified security authorisations, and finally deleted them.

    And just after this, my WiFi connection showed "connected" but I was unable to load any page.

    And in the notification box, there was a message I've never seen before : AVAST VPN SecureLine : Deconnecté (Disconnected). So in fact, do I have a VPN Client ? I don't think because it's not a free option for AVAST Antivirus. Do you think it is the cause of problems ?

    I'm currently using my phone 4g->wifi connection sharing with my computer, and it works.
    Because even after restarting the computer, the normal WiFi Internet is still unable to load anything (but still shows it is connected).

    EDIT : A few minutes after, the Internet was working, but my TAP0901'friend is still here, but TAPOAS has gone.

  • Search your whole directory for tap09, it still has 2 more DLL files (show hidden files), AVAST VPN secureline will bring the aos adapter you deleted now. 

    All the items need to be deleted in safe mode(without any options in safe mode.

    register tap adapter

    whole directory(`s) tap0901

    device manager deinstall all tap adapters/aos adapter

    you can check your avast install by programms and software, choose avast, than choose change. this should let you see all the installed components of avast.

    If any questions just ask!

  • google chrome adds the adapter for profile syncing, as in favorites , settings etc 

    I think due to this each update recreates the adapter, but i'm have not confirmed this

    This deletes all of them, but they still come back.  ON my device manager, I had over 600 TAP adapters, so this bat file definitely beat deleting them one by one.  It's not a permanent solution though.

  • ok guys just want to say all you guys who have tap32 adaptors returning stop using bit torrent or similar clients. I got this slight ipv9 problem from running wampserver because I couldn't get localhost sorted I tinkered a bit all I do is right click open network and sharing connections in the bottom right corner of desktop, then click change adapter settings right click the tap32 connection and disable, make sure it says network cable unplugged, then right click your normal WiFi connection and select connect, then close. Right click network sharing centre again then select advanced sharing settings scroll down and expand ' Guest or Public ' in network discovery select turn off. OK now open your web browser in my ase internet explorer select tools, then  internet options, select connections tab then LAN Settings tick automatically detect settings, making sure proxy server is unticked. ok mine is not to remove it but to stop it interfereing with your normal connection. right click TAP32 adapter again and select properties, untick client for MICROSOFT networks TCP/IPv6 and TCP/IPv4. In the sharing tab select allow other network users to connect through this computers internet connection this lets you untick the allow other network users to control or disable the shared internet connection now untick both select ok to close no one can use this connection until you change it back I haven't had a dropped connection from my usual wifi connection since

  • This is easy no need to remove anything, in win 8, 8.1 nor 10 TP,

    u guys just need to uninstall the device driver thru device manager and refresh it.after that go to search box and type in change device installation setting, if found just click it. Select "No, let me choose what to do", Select "never install driver from Windows Update." and tick "Automatically get the device apps and info provided by your device manufacturer." and click save changes. then restart your computer .. that shud do it . :)

    netsh winsock reset catalog
    netsh int ip reset c:\resetlog.txt

  • I've been dealing with this from the start of Windows 8 just like a lot of others. Finally today on my 2008 r2 server I saw a firewall log as to what time the TAP-Windows Adapter V9 was installed and Uninstalled. 

    Installed on 8/10/2015 at 11:36 am 

    Uninstalled on 08/10/2015 at 11:36 am

    I looked at the Event Viewer under Windows and system. I saw the following.

    08/10/2015 11:35 am - The Windows Update service entered the running state.

    08/10/2015 11:36 - The Software Protection service entered the running state.

    08/10/2015 11:36 - The Device Install Service service entered the running state.

    08/10/2015 11:36 - Driver Management has concluded the process to add Service tap0901 for Device Instance ID ROOT\NET\0000 with the following status: 0. ( this is the event in which the adapter was installed.)

    08/10/2015 11:36 - The Device Setup Manager service entered the running state.

    08/10/2015 11:36 - Driver Management concluded the process to install driver oemwin2k.inf_amd64_5a1fec2fbbccefcc\oemwin2k.inf for Device Instance ID ROOT\NET\0000 with the following status: 0x0. ( WTF is this? I don't know yet.)

    08/10/2015 11:37 - The Software Protection service entered the stopped state.

    Anyway, I have tried disabling the Device Setup Manager and Device Install service services to see if this resolves the issue. Any feedback is welcome.

    As far as I know these services do the following.

    Device Setup Manager - Goes out and pings windows update every night to see if any devices that are installed and set up to use windows up date to update drivers. 

    Device InstallEnables a computer to recognize and adapt to hardware changes with little or no user input. Stopping or disabling this service will result in system instability. (We'll see I imagine it really might cause instability but we are going to try it.

    No VPN used and I have tried removing everything non-essential.

  • Go to C:\program files there should be a "TAP Windows" folder, open and uninstall the VPN Adapter, all is done

    this issue mostly happens because of a VPN app installation

  • Hi, I thought this might help. 

    In device manager the driver properties of the tap adaptors showed that it was installing from 

    C:\Windows\System32\DriverStore\FileRepository and with folder names staring with oemwin2k.inf_amd64_

    Not to sure if I should do this but what the heck I got nothing to loose, so I set a restore point before I deleted the folders. 

    So I thought I had won, and I was just checking to see if they had gone permanently before I pressed submit and they reappeared, with the oemwin2k.inf_amd64 folders back in C:\Windows\System32\DriverStore\FileRepository.

    Not sure what else to try next. I've tried everything suggested in this thread.

  • Hey.

    I had the exact same problem as everyone, but I think I finally found a solution for it (just did it few minutes ago, so cannot be sure, but it's the first time for a long long time that I'm able to reboot without seeing any TAP adaptor popping up in the device manager.

    So, I found a thread on reddit very similar to this one and this is what I read :

    "Actually I might have figured it out for my computer. I uninstalled the Microsoft Office 2011 suite and it appears to have fixed the issue. Those network adapters aren't being installed anymore."

    and

    "Do you happen to use AutoKMS for the activation of Microsoft Office products? KMS creates these Multiple TAP-Win32 Adapters to keep the license in check."

    I hope this will work for you too.

  • Had this issue for months and couldn't figure it out. Thought the issue was related to the fact I was running Server 2012R2 on VMware but as soon as I disabled by KMS and rebooted the TAP adapters stopped automatically installing.

  • The reason you are seeing these adapters might be due to activation of Microsoft Office with AutoKMS. This will cause interuptions in your wi-fi connection and might even cause Chrome and other browsers to freeze. If you did use it, uninstall it using the same tool, and then delete the drivers from your control panel. Reboot and you should be fine. Your office might stop working... in that case, if you can't afford the 7$/month get openoffice...

  • Hate to say this but this solution does not work. It will end up replicating itself over time until your network connection drags to a halt. I have tried disabling, deleting and even removing its system permissions. Something keeps reinstalling it. I have also gone into the drivers folder and deleted it from there, but it will just re-appear.

    At the moment I am going through the registry and system files, as well as task scheduler to find anything that could be linked to it. Programs that I have/had that could have caused it look to be Cyberghost, PIA and even Avast anti virus. I have found the Open VPN installer and ran the uninstaller, but this has made no difference.

    If anyone else knows a more permanent solution then it would be great to know. I'm going to keep searching through the registry and systems files deleting anything that could be triggering it until this stops.

    If none of this works then an image refresh may have to be my only option.

  • to everyone who gets unwanted tap adapters I found out how to stop it!

    so problem is that two unwanted network drivers install itself each reboot..

    to fix!

    go to device manager uninstall, wow fixed.. just kidding you know itl install again on reboot..

    so in computer management go to task scheduler library find what it is that the trigger is that runs at start up.

    read more about it because you wouldn't want to disable the wrong thing...

    then restart couple times the network adapter should be gone.

    I did this just now and worked for me.

    was searching online for a while and couldn't find a solution.

    hope this helps anyone else!

    then restart couple times the network adapter should be gone.

    I did this just now and worked for me.

    was searching online for a while and couldn't find a solution.

    hope this helps anyone else!

  • Sorry for the extremely late response, but I had the same problem for a long time after upgrading from 8.1 to windows 10.

    For no reason, random tap V9 and tap win32 adapters kept appearing, and after uninstalling them from the device manager, they'd appear back after reboot.

    The solution for this problem for me was to do a combination of things.

    1. Go to your device manager, and uninstall all the tap adapters if there are any.

    2. Go to your system32 directory, and search for tap0901 and tapoas. Delete all the files that show up using administrative rights if asked.

    3. Obtain a program called PsExec, it can be found on the windows support forums as well, but I'm not sure if I am allowed to link here. A simple google search will do the trick. 

    Run CMD with administrative rights, and use cd to navigate to the location where you've left the PsExec file. I had mine on the desktop, so for me  it was "cd C:\users\jurrian\desktop". After that you want to run PsExec from the command prompt, by typing "psexec.exe -i -d -s c:\windows\regedit".

    You'll notice a registry window pop up, now be VERY CAREFUL! If you remove a wrong file and/or folder, you might brick or damage your pc in multiple ways, I will not be held responsible for any other files you remove. If you are not sure what you are doing, please stop now.

    Once regedit is open, you'll notice 2 columns, the left one being the folder browser, and the right one being one that shows the files in the selected folder. Press edit, and than find. Search for "tap0901", once regedit has found your file, select the folder which the file is in on the left column and delete it entirely. Press f3 to search for the next file, and keep deleting the folders containing something with tap0901.

    Once no more tap0901 files can be found, do the same for a file called "tapoas", and delete all the folders if there are any left.

    Reboot your computer, and you should be permanently clean from those pesky files!

    If you have any questions, feel free to ask, and I'll try my utmost best to help.

  • Good day Jurrian

    Thank you for your explanation on this issue!

    I have the same issue regarding duplication of the same 2 files, namely TAP-Win32 AOS and  TAP-Windows Adapter V9. I don't know when it duplicates itself, but it ads a #2 or #3 etc.

    If I'm not mistaken, I installed a VPN Software as I'm concerned about Internet Security etc. as I was previously hacked.  So, my guess here is that these 2 files only started to view in my Device Manager since I started using this VPN Software! I can't think that it's THAT harmful? As my VPN software depends on both these files!

    My only issue is that it keeps duplicating itself.

    Thanks for your assistance in this matter and hope you could give me some clarity on this?

    Kind Regards

    Antonio

  • After many many tentatives I solved the problem in this way :

    1) Install Lockhunter

    2) With Lockhunter rename the files tap0901.sys in tap0901.sysa and tap0as.sys in tap0as.sysa

    3) Always with Lockhunter try to delete tap09.sysa and tap0as.sys, and lockhunter will tell you that will be deleted at the next reboot

    4) Reboot the machine

    With this system automaticall are disapperad more than 20 TAP Adapater that I tried to delete many times !

    Now everything is fine

  • Its the Muslim who work in the ISP as mole. You cant catch them and you cant protect your network. I just find out I had this unwanted Tap-windows adapter installed days ago, it show up as ethernet2 which I didn't installed when I check with IPconfig /all. They did it because I was using CyberGhost to hide my IP + changed my public DNS to Norton. So they use this new method to hack our network. It has to come from the ISP, because I got a replacement router from Verizon 3 weeks ago, because I told them about the hack on my network, he suggested there might be virus on the router, but this is a brand new replacement right out of the box refresh. So it has to be someone from the ISP. Muslim did so much more than just hacking people.

    I reinstalled Wins8 6-7 times with software to format the harddisk for 6 hours every time. So Virus is not suppose to be on my hard disk or the new router. I did all this because I cant get the code by Hotmail in order to change password where there is two Microsoft remote tech working on my laptop right in front of my eye, but they both cant fig out whats wrong. My files from my flush drive got deleted. My email not showed up correctly when I used the laptop to login, but it showed up correctly with a cell phone login. Facebook account settings changed itself. Youtube and google comments never there after logout. When I checked my Youtube settings, middle east teens subscribe on my channel where I got no video for them to subscribe at all, so I block them. They did all this because they want to suppress our freedom of speech against Islam(no where close to peace). They also follow/stalk people in the local neigborhoods, they work in groups so is very hard for cops to catch them. So use your logic guys, if you see something, say something. Tell the cops whats want by using FBI Tips hotline. These people want us to shut up, so they can do whatever they want and screw our country. Don't be a ghost, check your comments if it still there once you logout out. Play smart guys !!!!

  • Its pretty much useless if the Muslim got mole who work in your ISP as an employee.

  • Get devcon.exe from Microsoft.

    Run it.

    Type "devcon remove =Net *tap0901*"

    It'll remove them all.

  • Guys, I too have this problem.  I really want to keep my TAP driver, though because it's used by Ivacy VPN.  I want to use my VPN.  I've noticed that Windows 8.1 or Windows 10, whichever it is, will regularly refresh the whole system.  This too is very irritating because it kicks my graphics card and I have to restart the game I'm playing.  However, one of the advantages of this regular refresh is that it also kicks the wifi back into place.

    Is there any way I can manually get Windows to do this refresh?

    Do you have any ideas on how I can keep my VPN but still use the TAP drivers?

    How do I uninstall and reinstall the TAP drivers?

    Thanks for any help you can give.
