Almost all organisations have Password Expiry set via Password Policy in the Domain. They also have an Account Lockout Policy implemented.

Almost all organisations have users who save and cache their passwords, with the hope that once their passwords are saved, they wont be prompted for passwords again. As if it takes too much of toll and work to enter password and validate credentails !!

The result of saving and caching password is that once the User changes his password, he forgets that he has old passwords cached and that he needs to clear all those old cached passwords. When the User does not do so, applications may continue to use the old passwords behind the scene.

This will result in User's account being LOCKED because there is a working Account Lockout Policy which will lock the User-Account after say 5 bad password attempts.

All the above encouraged me to write this tool. What this tool -- wiper.exe -- does is:

This tool is simple to use and requires no special privilege to be granted to user-accounts. The zip file also contains screenshots.

Updated the tool with command line switches. Now this tool can be executed from command line as well. With the latest update this tool can be executed using SCCM or any other centralised manageability enterprise product. The administrator can use SCCM or other products and execute wiper.exe with command line switches to run on all target machines from one central location.

The command line switches are

Note: You must separate the EXE and the command switch with one blank space. For example: Wiper.exe "-ClearAll"

Please feel free to rate this tool.

Enjoy !!
