Windows 10: Windows 10 stuck on Diagnostic Mode, tried safe mode and it won’t accept my password

Alright to make it short, yesterday I tried diagnostic startup since I was having some problems with my PC, and now I’m stuck on it since I can’t enter a PIN. I’ve read every solution saying to “recover PC” or “restore previous configuration”, everything in safe mode, but when I choose any of these options I’m asked to choose an account and enter the account password. I tried it and it won’t accept it even when it’s completely correct. I’ve changed it 2 times trying to figure out if it’s a bug or something and it still won’t work! Help please I’m desperate!

Password not accepted in Safe mode

Hi,

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?
• What is the critical error you are getting?

If you are using Windows 10. To go to safe mode you have to follow the below steps.

If you are able to go to login screen in normal mode try the below steps to go to safe mode with networking.

• 
  At the login screen click on the power symbol.
  
• 
  Hold SHIFT + Click Restart.
  
• 
  After restarting your system, select the Troubleshoot option.
  
• 
  Select advanced options under
  Troubleshoot screen.
  
• 
  Click on Startup Settings.
  
• 
  Click Restart and follow the onscreen steps to go to
  Safe Mode with networking and check if you are able to login.

Stuck in diagnostic mode, PIN # not accepted, please help

I had no issues with my computer prior. I simply was following some online suggestions for ways to reduce lag in an online game we like to play. The suggestion was to turn diagnostic mode on, which I did. I shut my computer off and when I turned it back on and entered my PIN # it said it was incorrect, yet, it is indeed correct. This started a week worth of nonstop research on how to undo this mess. I can hold the shift key down while restarting my computer and I get a blue screen where I have several options. I have tried restarting my computer to previous version, does not work. I have gone to troubleshooting, advance, options and I get to the point that I can see a list of options like safe mode and etc. but cannot click on any options in the list, instead it says restart computer to get me to those options which when I restart takes me right back to the Windows login screen. I tried to pull up command prompt and it asks for my PIN # which it will not accept. I click on forgot password and it restarts PC and takes me right back to the windows login screen where my PIN is still not accepted. I try to get to safe mode, it asks for the user account and then the PIN # that again, it will not accept. I have turned the PC on and off 3 times to start the auto repair and it just takes me to the same screen as holding down the shift key when restarting. I don't know what else to do, I cannot get to safe mode because it requires a PIN # that it does not accept, I cannot get into command prompt because it requires a PIN # that again says is incorrect, I cannot get anywhere with any of the online options or directions I see that works for many people. WHAT DO I DO? Any help or suggestions??
