Windows 10: 0xc00021a bootlop (also in safe mode) after installing OpenVPN

First of all, hello everyone... this is my first post, and I hope I chose the right subforum, in spite of not being able to provide a log *Think

My Windows 10 recently got stuck in a bootloop (BSOD 0xc00021a) since I installed OpenVPN client. Safe mode also crashes and for some reason I discovered I have no restore points (duh!). So I'm starting to get somewhat desperate, because I exhausted all the possible solutions I could find after quite some googling, using the console in the recovery mode:

• Tried WMIC to uninstall, but "wmic product get name" throwhs the error "invalid class".
• Tried browsing to the OpenVPN program folder searching for some other uninstall option (e.g. msi) with no success.
• Uninstalled a few drivers I thought plausible, from those offered to me by the DISM command: vonva-6.inf (Cisco Annyconnect VPN I guess), avmaura.inf (FritzBox remote USB interface) and qcm20q.inf (Quanta Computer, no clue where it comes from). No OpenVPN-related driver seemed to appear.
• Renamed the OpenVPN installation folder (yeah, I'm starting to get desperate, I urgently need my PC and a few things I recently worked on).

Any idea about how I could uninstall OpenVPN, or at least boot into safe mode? Maybe if someone could tell me the exact program name (for WMIC) or the driver files of OpenVPN that might already help. Or some workaround to edit startup services or drivers from this awful recovery command line?

Any kind of help will be greatly appreciated!

Regards!

Thank you for posting your query on Microsoft Community forum.

Have you tried all the above steps suggested by Sangeeta Sarkar on September 13, 2015.

I would suggest you to provide some information to help you better.

• Are you trying to login the Microsoft account or the Local account in safe mode?
• Did you try with only safe mode or safe mode with networking?

Safe mode problem

Hi,

To get better clarity on the issue, kindly answer the questions below:

• By saying that you have a "Safe mode problem," did you mean to say that your computer is stuck in Safe mode or are you unable to boot it to Safe mode?
• What troubleshooting steps have you attempted to resolve your concern?

If this is caused by recent programs installed on your computer, then we suggest you to run
System Restore to revert your system files to an earlier date. To run System Restore, follow the steps below:

• Press Windows key + R on your keyboard.
• On the run command box, type "RSTRUI.EXE" and hit enter.
• Follow the on-screen instructions.

Make sure that you choose the restore point date when your computer was working fine. Please be advised that programs and applications installed on your computer after the restore point will be removed.

Let us know how it goes.

 

Boot into Safe Mode on Windows 10  


I am stuck in Safe Mode in spite of following all the suggested steps to go back to Normal Startup - Like opening file location of msconfig.exe & running as Administrator. The computer I am trying to get out of safe mode has just been updated from Windows 7.
