Windows 10: Password not working in System Recovery Options

My OS is failing to boot and also to automatically repair itself. I am then greeted with this System Repair page:But every option I select needs my MS Account password.I am using the correct password but it does not work...I am now completely stuck. I need to enter the command prompt in order to fix the issue. Edit: I uploaded screenshots, but they are somehow not visible....

hdd password recovery

howdy. if this isnt the right forum please move it.
a friend has a 3 year old hp or compaq tower. they called me to help. they are not able to get into the admin accound, because the password was changed. it was changed by them when a popup told them for security they should change thier password.
after it was changed they could no longer get into the admin account with the password they changed it to, and the computer started sending out emails to everyone on her address list with porn and viagara type adds.
i ran anti virus and we found 20 trogans, virus, ect. everything comes back clean now, but we still cant get into asdmin account to format drive.she doesnt have a vista system disc, just the recovery partition.
1.. is there a way to get the password?

2... if not can i install a new hdd and install from her recovery partition?

3...will i be able to install new hdd and install vist from my disc or is the mb set up to not alow that?

thanks for any help, they are on a limited budget and are true friends to me and i would like to help them. thanks! sam

 

Windows 10 recovery options ?.

When the password is wrong and the pin number is wrong is there a way recover the data or even the OS ?.

The extra added issue to this is that the systems running UEFI so no inputs working on boot, so how do you get in to the recovery options.


Could it be as simple as plugging in a USB drive with windows 10 on it and hoping it boots up off it ?. It's the only option not tried as yet as the owner of the system as just got out of hospital wanted to try passwords and pins which seemed to fail every time even though he\she is pretty sure are right.

I am thinking that's the way to go is there any other ways to gain access other than taking the drive out of the system. Data on the system is important too.

 

Lost password and lost recovery option

Regarding this concern, we’d like to confirm also if you’ve already tried resetting your password. If you haven’t done it yet, click this link for

In case that resetting of password will be unsuccessful, we suggest that you use theaccount recovery form as the
last option to get you back and access your account. Recover your account
