Windows 10: How to unlock desktop PC without password?

I am trying to unlock my desktop PC that has not been used for several years. I forgot a password so I'm not able to access my computer.I was looking for a solution online, and found some. I tried to open Command Prompt via "Advanced options" but after I click Command Prompt my PC restarts and nothing is happening for a long time, the screen is just black. Also, it happened that I got "Choose your keyboard layout" screen, but when that happened I wasn't able to proceed keyboard and mouse weren't responding to any clicks

Desktop unlocking puzzle


I have a GKChain Gatekeeper device. It consists of a USB dongle and a separate battery powered key which I keep on my belt. I suspect the key and dongle communicate via BlueTooth protocol, but I may well be wrong. It makes no difference though.

The USB device locks my desktop when the signal from the key falls below a pre-set level. When the signal comes back, it unlocks my desktop (by knowing my ID and password).

However, the unlocking sequence seems a little erratic. I can approach my PC, and I hear the "Notification" sound, which I presume is associated with the Desktop Unlock event. Usually, the desktop unlocks, as it should. But occasionally, I end up at the login screen instead, and am obliged to select my userid and enter my password. The whole point of installing the Gatekeeper was to avoid having to enter my password... (whilst remaining secure)

It's hard to see what might be going on, as I use the desktop lock/unlock events to trigger a program which turns the display power off/on as appropriate. I'm going to suppress the display off part of my program after I've submitted this thread, in case it sheds light on what's going on.

In the interim, does anyone have any suggestions why I should be getting the sound that I associate with Desktop Unlock, but without the desktop locking?

Might I find some clues in the system Event Log?

 

How to disable bitlocker auto unlock when my windows account password was changed?

How to prevent auto unlocking drives from my laptop when my windows password changed? Hack or change my account password to much more easy than decrypt disk, but why windows doesn't provide such functionality from the box? I looking for any scripts to auto unlock from powershell also.

I'm not going to "just disable unblock". It's very useful thing. I have too many things which starts from encrypted volume. I want to prevent access to my volume only just getting my account. If my system administrator account could be hacked, all sensitive data would be lost.

Steps to reproduce:

1. Login into your account
   
2. Set up bitlocker, auto-unlock
   
3. Restart PC and login into account
   
4. Drive unlocked
   
5. Logout from account (I switched off whole PC)
   
6. Ask sysadmin to change your password to new one
   
7. Login into your account with new password
   

Expected result: bitlocker drive locked

Actual result: drive unlocked
