Which registry cleaners can repair the blue screen error that is free to use? I have already used ccleaner and that doesnt work and perfect optimizer is not free

BSOD: Copied over /repair/software and now can’t login!?
My work computer recently stopped working. When I boot it up, it gives me blue screen with hive message can’t find system32\config\system. I went into recovery console but it wanted admin password which I don’t have and corporate won’t give me. I don’t want to send it in and wait to get it back, so I hooked up hdd to a desktop and copied c:\windows\repair\software to c:\windows\system32\config\sof… Put hdd back into laptop and booted up and it boots into windows! However, it doesn’t recognize my username/password anymore. What can I do to fix this?

Thanks!
i’m not hacking it; i’m simply fixing it like i would if it were mine, but now my username/pw no longer works; i’m in IT, but i’ve never run into this problem before; they can’t give me the admin pw because it’s the same for the entire company, but i can fix it on my own to save the company a lot of money; and i’ve made backups so everything i do is reversible; i simply need this to work so I can do my job
Well this is the answer I get? And from a "top contributor" at that.

I have Windows Vista Home Premium. My computer has become very slow. I know this is because of my registry, because I uninstalled most of my slow programs, and my computer still isn’t running the way it should. Where can I find a high quality registry cleaner that will get deep down into my system and fix it, but won’t get deep down into my pocket and empty it. In other words, where can I find this registry cleaner for free? Also, what do you recommend?

Please no answers for free points, because I will report them. Also, do not answer with an "I don’t know" unless you have some valuable information following it.
