Give physical access to the machine, it’s pretty trivial in Linux/Unix as long as the root partition is mountable on a running system . In fact, if the Windows file system is mountable on a Linux machine, the passwords don’t matter. If the file system or the files in question are encrypted, the problem is non-trivial but not impossible. There is only one truly unbreakable crypto system, but the key is the same length as the plain text and is impractical to implement. Pretty much all other crypto systems depend on the ability to factor very large composite numbers. Do that quickly and... Bob’s yer uncle.
