lsass.exe error

I got an lsass.exe error when i try to open windows xp on my netbook.  i understand this is a virus and the best thing to do is reinstall windows, however i have a couple of .mwp docs that i CANNOT lose in my current windows, that represent about a years worth of work. Also since i have a netbook i have no wiindows disc, and i'd like to know how i can go about obtaining the windows reg#.  thanks



The process lsass.exe is the Local Security Authentication Server. It is a safe file from Microsoft. Lsass.exe is responsible for security policy enforcement within the operating system, verifies users logging on to a Windows computer or server, handles password changes, and creates access tokens. It also writes to the Windows Security Log.


Follow the steps from “How to recover from a corrupted registry that prevents Windows XP from starting

“Error message that you receive when you restart a Windows XP-based computer: "lsass.exe unable to locate component" “
