Windows 10: WIN 10 Admin password not working.

As much as I wish I had a solution for you I must admit to being a not real smart techie as I never assign a password to the hidden Administrator account, maybe because it is Hidden on purpose, by default. A suggestion would be to find a password removal tool on the 'net that can be used to create a bootable CD then remove any passwords without Windows actually running.

 

I don't know if this will help with your situation or not but this is a guide to convert a Microsoft account to a local account. It was written for Windows 8 but I read it will work on Windows10. I have not tried this myself. This thread was posted in another forum. On page 2, posts 14 and 15 is the guide.

Windows 8 Microsoft Account password hack.

If you decide to try this make a backup image of your hard drive. Just in case something goes wrong. Also backup the Windows registry.

Good luck

 

I was in the same boat where I had set my Win10 machine to safe mode, but forgot the password since I had been using a 4 digit passcode. Here's a solution that worked for me after trying a bunch of other things. Download pcunlocker from here: Reset Lost or Forgotten Windows Password with PCUnlocker

I unfortunately did have to pay $29 for it, but it saved me a lot of headache. When you download the unlocker, you'll get an iso file that you have to copy as an image to a usb key. I used a program called iso2disk which is free to do that. There were a few other steps that I had to do in the bios of my notebook to allow me to boot to usb. That involved switching the boot mode to classic.

Once you boot with the unlocker program, you can simply remove the password from that account, then you will boot back up to windows.

 

There's a program on Kyhi's Recovery Tools that is called NT Password Changer or NT Password Unlocker...and it's free.

Dude...

you saved my dumb as after enabling "SafeMode" via msconfig to initially solve some "System Recovery Issues". I tried several USB-Sticks with MS-DART, all gave me an error editing the BCD back to normal mode, sometimes they could find the BCD or had no acces.

After downloading the Windows Rescue PE from your Link an using NTPW, i've managed to Unlock the stadard Adminaccount and reset the Systemstart to Normal.

I Love you and thx so much for the provided Link. Hope someone reads this to who has the same Problems!
