Issue Details

I have forgotten or lost the password on my Windows PXI Embedded Controller. Does National Instruments have a tool to let me get back into my controller or reset my password?


National Instruments does not have any tools that would allow you to circumvent entering the user password. 

Unfortunately, there is not a method supported by Microsoft for logging into a Windows system for which you have lost the password. In this situation, Microsoft recommends that you reinstall the operating system.

It is possible that the password for the user name "Administrator" was left blank; a blank password field with this user name is a good thing to try first. However, there is no guarantee that this will work.

If this doesn't work, you can restore the operating system on a National Instruments PXI controller using the built-in Acronis True-Image or Phoenix Firstware. Additionally, you can use the recovery media that was shipped with your PXI controller, but this option should be used after attempting an Acronis or Phoenix Firstware recovery.
