The answer is MRU lists in the registry. This is the correct choice because the Windows MRU list registry artifact is specifically designed to track the most recently used files for individual applications, storing paths and timestamps under keys like NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSavePIDlMRU. On the Computer Hacking Forensic Investigator CHFI exam, this artifact tests your ability to trace user file activity through registry forensics, often appearing in scenarios where an examiner must prove which documents a user accessed. A common trap is confusing MRU lists with Jump Lists or Prefetch files—remember that MRU lists live exclusively in the NTUSER.DAT hive and are application-specific, not system-wide. Memory tip: MRU stands for “Most Recently Used,” and think of the key “ComDlg32” as the common dialog box that logs every file you open or save.

Which Windows artifact is specifically designed to track the most recently used (MRU) files for specific applications and can be found in the NTUSER.DAT registry hive?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
MRU lists in the registry
MRU lists are stored in the registry under NTUSER.DAT\(various keys such as \Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSavePIDlMRU). They track recently opened files.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Prefetch files
Why it's wrong here
Prefetch files are stored in C:\Windows\Prefetch and track application startup, not MRU files.
✗
Jump Lists
Why it's wrong here
Jump Lists are stored in %APPDATA%\Microsoft\Windows\Recent\AutomaticDestinations and are separate from registry MRU.
✓
MRU lists in the registry
Why this is correct
MRU lists are registry keys that store recently accessed files for applications like Notepad and WordPad.

✗
LNK files
Why it's wrong here

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
