Yes of course. Just select an attack type and leave the whole task to the program will be OK. There is no human interaction needed. When the attack is finished, the program supports to shut down the computer automatically. So, it is quite easy to use.

For example the possible password length, the possible characters in the password, the cases of the password, etc. Brute-force with mask attack is to look up the password according to the hints you offered to the program. When compared to brute force attack, this brute-force with mask attack is based on password clues, which is time-saving.

Dictionary is a commonly used terminology in the field of password attack. The dictionary is a text file that the program is based on to attack the password. A dictionary is listing characters, numbers and character sets and the like which may be the most frequently used as password parts, like a, ab, 12, 09, ab1, etc. The program is to look up the password based on the dictionary. This dictionary can either be the integrated dictionary file or a dictionary user creates.

Changing Program Priority allows you to control the allocation of processing resources on your computer. A multi-tasking operating system such as Windows, allows you to run multiple programs simultaneously, but most computers have only one central processor. This means the OS must divide the total amount of work, and the processor must perform between those programs. While each application has a priority that is automatically determined by the OS, the default allocation of resources among running tasks doesn't always provide maximum system productivity. So you may set the program priority for preferred system productivity.

A computer processor is described as Idle when it is not being used by any program. If you choose Idle here, it means the processor will only perform Office Password Recovery.

While the computer processor is performing multiple programs simultaneously, if you set the PDF Password Recovery as High, it indicates the processor will allocate more processing resources to it. This will definitely increase its performance. However, in this case, other programs on the system won't receive an appropriate share of processing resource, which may reduce their performances.

For the demo version, passwords longer than 3 characters can't be displayed. Remove all passwords from the file is not available either. The full version can attack passwords of any length and supports to remove all passwords from the file for editing.
