The correct answer is the SYSTEM hive, specifically the key `CurrentControlSet\Control\Windows\` and the value `ShutdownTime`. This works because the ShutdownTime value records the exact timestamp of the last system shutdown in Windows 10, and since a boot event immediately follows a shutdown, querying this value effectively reveals the last boot time. On the Computer Hacking Forensic Investigator CHFI exam, this tests your knowledge of core Windows registry artifacts for timeline analysis, often appearing in scenario-based questions about determining system uptime or correlating user activity with boot events. A common trap is confusing this with the `SYSTEM\Select` key, which tracks the last known good configuration but not shutdown timestamps. Remember the mnemonic: “Shutdown tells you boot” — the last shutdown time is the start of the next boot.
CHFI OS and File System Forensics Practice Question
This CHFI practice question tests your understanding of os and file system forensics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A forensic analyst is examining a Windows 10 system and needs to determine the last boot time of the system. Which registry hive and key should the analyst query to find this information?
Why wrong: NTUSER.DAT stores user-specific settings, not system boot information.
B
SYSTEM hive, key 'CurrentControlSet\Control\Windows\', value 'ShutdownTime'
The 'ShutdownTime' value in this key records the last system shutdown time, which can be used to infer the last boot time (as the system boots after shutdown).
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SYSTEM hive, key 'CurrentControlSet\Control\Windows\', value 'ShutdownTime'
The SYSTEM hive stores system-wide configuration data, and the key 'CurrentControlSet\Control\Windows\' contains the 'ShutdownTime' value, which records the last system shutdown time. Since the last boot time is effectively the time after the last shutdown, querying this value provides the necessary information. This is a standard forensic artifact for determining system uptime and boot events on Windows 10.
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.
✗
NTUSER.DAT hive, key 'Control Panel\Desktop\'
Why it's wrong here
NTUSER.DAT stores user-specific settings, not system boot information.
✓
SYSTEM hive, key 'CurrentControlSet\Control\Windows\', value 'ShutdownTime'
Why this is correct
The 'ShutdownTime' value in this key records the last system shutdown time, which can be used to infer the last boot time (as the system boots after shutdown).

Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the misconception that the SOFTWARE hive or NTUSER.DAT hive stores boot-related timestamps, but only the SYSTEM hive's 'CurrentControlSet\Control\Windows\' key contains the official 'ShutdownTime' value for determining last boot time.
Detailed technical explanation
How to think about this question
The 'ShutdownTime' value under 'CurrentControlSet\Control\Windows\' is a 64-bit FILETIME structure representing the last system shutdown in UTC. In forensic analysis, this value can be correlated with event logs (e.g., Event ID 6005 for boot, 6006 for shutdown) to reconstruct system activity timelines. A subtle behavior: if the system crashed or experienced an unexpected power loss, the 'ShutdownTime' value may not be updated, requiring alternative artifacts like the 'LastBootTime' from the 'HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters' key or the 'BootTime' in the 'HKLM\SYSTEM\CurrentControlSet\Services\EventLog\System' key.

→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.
