Windows 10: My PC won't start and to do anything in advanced repair I need a password which I don't know.

Recently my windows 10 pc wasn't able to start because of bad system config info. I messed up and changed security file in D:\Windows\System32\Config\Security\and now if I try to do anything in Advanced repair it asks for password, I type in the password and it doesn't work. I have a ton of my personal files in this computer and I don't want to lose it. Please help

Dolby advanced audio v2 (Windows 10 don-t work)


Hello guys!I have a problem with advanced audio v2 on windows 10 don-t work

 

Volume Mute Light won´t change color

I can´t find anything that addresses my actual problem.I have seen that others have also experienced this problem but I have not found a solution that works. My ProBook was originally Win 7 pro, updated to Win 10 pro but HP won´t update because of its age (for me, brand new-just bought it a few days ago) so I don´t really know what to do. Sure, just a minor glitch but a very irritating one (that orange is just way too bright!) that should be a snap to fix (or not-I don´t know, I think my 4 year old granddaughter has better computer skills than I do!) English is not the default language so many of the commands must be translated-just another hassel to deal with. I finally found the systemconfig. box. Selective start and discovered that ALL the service boxes are checked. Good, bad, doesn´t make a difference: I just don´t know.
