Atomic Word Password Recovery is the tool of choice, it supports most of the document encryption algorithms available in MS Office. There are several different methods of attack available in Atomic Word Password Recovery.

There are two recovery modes available in Atomic Word Password Recovery :

Extensive search - automatic mode which just removes your password. If this mode is set, the program modifies the password protected document in such a way that the document becomes unlocked and the password is not required anymore. It's a slow method, but can guarantee 100% password recovery. This method is easier to use, there are no options to tune, the only thing you should do is to select your password-protected Word document.
Password template - manual user-defined mode to recover your password. You can try to start this user-defined mode if you have any idea about words, and characters you think were involved or surmise what was password's length etc. The program will generate a large number of possible symbols combinations exhaustively working through all of them, checking one-by-one in order to find the right password. This mode will take less time then the first one.

Dictionary attack - under this mode, the program finds passwords by using special word lists, all provided passwords are checked. If your password is a known word (not name or so) then you can use Dictionary attack as this method could speed up things to about 1/2 an hour. You can get Dictionaries (word lists) on the Internet, some dictionaries are available in Dictionaries section of our website.

The following MS Word versions are supported: Word 97, 2000, 2002 (XP), 2003. 100% password recovery for most of file types.
