I like to run Command Prompt in Safe Mode to do System File Check but I got to a screen that I need to input a password so I entered the password I use to login Windows but every time (5x) it told me the password is incorrect.
The Windows login password is still valid I just used it to login of the computer using to start this thread.
 
What password do I use? Edit: To answer my own question, the password needed was the Microsoft Live account password to login.
What if anything else should I know that I could be doing wrong?
 
Back story, I have already run sfc /scannow with Command Prompt as administrator with Windows fully running and some things are corrupt but could not be fixed next step is to do the above.
I have one restore point but it is after the last Windows Update that I suspect caused all of my issues.
 
Thank you for your help in advance.

I used How to Start Windows 10 in Safe Mode with Command Prompt to guide me.
Till I got to
"At this screen you should press the number 6 key on your keyboard to enter Safe Mode with Command Prompt.
Windows 10 will now boot and you will be presented with the normal login prompt. Enter your password, and you will be brought directly to a Windows Command Prompt rather than the normal Windows desktop as shown below."

I was using the Lenovo OEM wired USB keyboard and my guess is USB 2.0.
Edit: The keyboard is 100% working.

Just use normal safe mode.

Just use normal safe mode.

What's that?
 
By the way how can I use the CBS.log to help me?

Select option #4 (Enable safe mode) instead of option #6. (Enable safe mode with command prompt)
 
The cbs.log can help you track down exactly what the problem is.
 
For the system file checker error "Windows Resource Protection found corrupt files but was unable to fix some of them" try the following...
 
Try running offline system file checker... https://www.thewindowsclub.com/run-system-file-checker-safe-mode-boot-time
 
For the DISM 605 error try the following...
 
Insert your installation CD. From Command Prompt (Admin), run:
 
Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:X:\sources\install.wim:1 /limitaccess
NOTE: Replace X with the drive letter pointing to the installation CD
 
If you continue to have issues.... try Reset This PC or Fresh Start. 
 

As long as the repair disk has the install.wim file on it you can use it.

Thank you Sajin but I'm done for now messing around with this computer.
I am starting to believe that the last bit of broken stuff is superficial like the Mail and Calendar app, Xbox Game Bar, Reliability Monitor are left not fully functional and could be other things I have not noticed.
Besides I think I need a decoder ring (ha-ha) to read the Component-Based Servicing and the Deployment Image Servicing and Management logs. I do understand some of it but not all and don't know how to use it apply fixes. Would teach myself first.
At this point I'm just going to wait until the next Windows update in four days and cross my fingers the broken stuff gets replaced/fixed.
The last last ... last thing I want to do is rebuild my system drive after a resetting or doing a fresh start than trying to find and installing everything apps/programs. The last time it took almost a month.
 
Edit: This doesn't change my mind about Windows Updates will still be applying them and understand things can go wrong and this is the first time something has gone horrible wrong in a long time for me.

Using FF I went right to it from the link in your other post you mentioned above > https://support.microsoft...ates-or-driver-updates
 
 

Your favorites might be in the C:\Windows.old\Users folder or somewhere in Windows.old if it exists..Might be hidden and need un-hidden.
