I described a way to compress the Windows registry manually yesterday. The process itself was not really complicated but it involved booting into DOS to complete the changes to the registry that have been made by the process. Tehmul (more of that please) commented in that article pointing to a software named NTREGOPT (NT Registry Optimizer) which would optimize the full registry and perform the replacement during the next system boot automatically.
How to display all Windows passwords
Just a few days ago I was describing a method that would allow anyone to change passwords for all windows accounts using a boot cd and a program called NT Passwords. This is great if it does not matter if you change the password for, lets say, the administrators account. It might however be sometimes important to get into an account without the owner of the account knowing – and he would surely find out if his password would not be working anymore.
