This is a conflicting problem related to the applications installed in your computer. If you have an HP laptop, try to uninstall everything related to protection tools:
-Device Access Manger for HP ProtectTools
-Privacy Manager for HP ProtectTools
-Drive Encryption for HP ProtectTools
Reboot the computer then come back and the errors should disappear. In case you still have problems, reboot the computer, press F8 and enter Safe Mode.
Open a Command Prompt and type: net user password. Change the info then reboot normally. The error should be gone now.
