I’m not sure I follow so I’ll answer the question I think you’re asking.
- Get him to reset his password to whatever he wants using this site (if he’s happy with his existing password then ignore this step)
- If he’s got files encrypted under another password then as long as he knows that password then he can decrypt his files
- Drag and drop all of the files which are encrypted – with the password that he doesn’t want – and decrypt them
- Now re-encrypt all of the files that you’ve just decrypted (it’ll use the new password by default)
AxCrypt doesn’t use the Windows Registry to store user passwords; it’s a security risk. AxCrypt retains the password in memory until the user logs out of AxCrypt or restarts his computer.
