2. RunMRU Start->Run


RunMRU is a registry key that records the commands executed through the Start -> Run feature in Windows. This key is located within the NTUSER.DAT hive at the following path:


NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU\


Through cmd query


reg query HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU


and Manual extraction of registry through cmd and take home to analyze


Reg Save HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU C:\Users\User\Downloads\output1.hiv



By analyzing the RunMRU key, forensic investigators can gain insights into the actions performed by users on the system, including the commands they executed via the Run dialog.

3.UserAssist

UserAssist is a crucial component of Windows systems, particularly for tracking GUI-based programs launched from the desktop. Located within the NTUSER.DAT hive, specifically under


NTUSER.DAT\Software\Microsoft\Windows\Currentversion\Explorer\UserAssist{GUID}\




One notable aspect of UserAssist is that all values are encoded using ROT-13 encryption, adding a layer of security to the data. This encryption ensures that sensitive information about program execution remains protected.

Understanding UserAssist involves deciphering the GUIDs associated with different functionalities.
