SIDDecode

SIDDecode is a small software application whose sole purpose is to help you find out the username and domain of a custom SID (Security Identifier). Each account has a unique SID value of variable length and is issued by an authority (such as Windows domain controller) in order to identify a user account, group account or logon session.

The advantages of being portable

The utility comes wrapped up in a portable package which can be deployed on your system by simply running the EXE file and bypassing the installation process. In addition, you may copy it on any USB flash drive or other devices and open it on the target computer without administrative privileges.
The portable running mode ensures your Windows registry doesn’t get clogged up with extra entries. Uninstalling the tool from your computer implies only the deletion of the files that you have grabbed from the Internet.

Minimalist looks

SIDDecode adopts a simplistic and clean layout that doesn’t hide any intricate configuration settings under its hood. It doesn’t offer support for a help manual but the dedicated parameters are highly intuitive so even rookies can venture into tweaking the entire process on their own.

How it functions

SIDDecode gives you the possibility to enter the SID value in a dedicated panel. You can either opt for manually typing in the data structure in binary format or paste the information from third-party applications. Upon decoding the SID value, the tool reveals information about the username and domain in the main window.

Bottom line

All things considered, SIDDecode provides a straightforward way for helping you decode SID values, and is suitable for all types of users, regardless of their experience level.
