220-1102 Operating Systems Practice Question
A user accidentally deleted an important file on Windows 10 and emptied the Recycle Bin. The file is needed urgently. Which built-in feature should the technician attempt to use FIRST to recover the file?
⚠ Common exam trap
Many candidates confuse System Restore (which affects system state) with file recovery, or assume File History is always active by default, when in fact Previous Versions can recover files from existing VSS snapshots without any prior user configuration.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Previous Versions
Previous Versions, because this feature leverages Volume Shadow Copy (VSS) snapshots to restore earlier copies of files or folders, even after the Recycle Bin has been emptied. It is the first-line recovery method for accidentally deleted files on Windows 10, as it does not require a separate backup solution or system state rollback.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
System Restore
Why it's wrong here
System Restore creates restore points that snapshot system files, drivers, and registry settings, but it does not track user data files in profile directories like Documents or Desktop. Deleting an important document does not alter the system state in a way that System Restore would capture, and even a restore point made before the deletion would not contain the file's contents. Therefore, rolling back to a restore point cannot resurrect the deleted file.
- ✗
File History
Why it's wrong here
File History is a configurable backup feature that continuously copies versions of files in monitored folders such as Libraries, Desktop, and Contacts to an external or network drive. However, it must be explicitly turned on before the deletion, and if it was never enabled or the file was not in a monitored location, no version history exists. Even when enabled, the recovery process requires browsing through File History timestamps, not an automatic restore.
- ✓
Previous Versions
Why this is correct
Previous Versions uses Volume Shadow Copy (VSS) to create point-in-time snapshots of entire folders or volumes without requiring an explicit backup routine. While Windows automatically creates shadow copies as part of system restore points or scheduled system tasks, these snapshots are not guaranteed on all files, but when available, right-clicking the parent folder and selecting 'Restore previous versions' can retrieve a deleted file from the shadow copy taken before the deletion. This makes it the only option listed that can recover a user file without prior user configuration.
- ✗
Backup and Restore (Windows 7)
Why it's wrong here
Backup and Restore (Windows 7) is a legacy utility that requires the user to have previously created a system image or file backup to a separate storage device; it does not perform continuous capturing or shadow-copy-based recovery. On a typical workstation, this feature is rarely configured unless someone manually set up a scheduled backup, and without an existing backup it cannot recover the deleted file. Even with a backup, it restores from the last scheduled snapshot, which may not include the exact latest version of the file.
