When we turned on our computer, before starting Windows, a black screen appeared, mentioning "WINDOWS\SYSTEM32\CONFIG\S
YSTEM is missing or corrupt".
I tried to solve it with the Windows XP resolve console, according to instructions at Microsoft site.
I've made some changes at the console, such as: moving files as System, Software,Sam, Security, Default to a temp folder, and afterwards it was already possible to access Windows logged as administrator, in the safe mode.
We were not asked any password to enter Windows, but, for instance, if I logged out, it was impossible to re-enter, because I was asked a password I did not have.
The problem is that I knew my password, and apparently when I worked in such files, the password was lost and I do not know how to recover it.
I believe I have passed all necessary information, but if you need some more, please read the Microsoft instructions text, in address below, which I have used to proceed this.
I need to recover my password, and I thank you indeed for any help you could give me.
