Anyone who's ever tried to open or edit an important Microsoft Word or Excel document, only to find it's protected by a long-lost or never-known password, will appreciate PasswordUnlocker's Office Password Unlocker. It's a handy tool that unlocks password-protected Word, Excel, PowerPoint, and Access documents so they can be opened and edited by anyone. You can also use it to recover forgotten Office passwords. It's compatible with all versions of Microsoft Office from 97 to 2007.
Office Password Unlocker opens with a basic gray dialog box typical of the Office family, which means functional but unexciting in an efficient, businesslike way. You can select one of three password attack modes: Brute-Force Attack, Brute-Force with Mask Attack, for when some password symbols are known, and Dictionary Attack. The Dictionary Attack mode is based on a customizable dictionary that you create to your specifications. There's a Help file in the File Menu and functional control icons. You enter the full file path to the locked document, click OK, and Office Password Unlocker gets cracking. There's an option to save a recovery process to resume it later, if it's interrupted or runs long. In tests, the program quickly unlocked Word documents for opening and editing.
Office Password Unlocker is free to try and $18.69 to buy. The trial version won't display passwords longer than three characters, and it disables the Password to Open and Password to Modify command. It works in all versions of Windows from 2000 to 7, including NT and Vista.
