Is Enable_changing_lock_screen_background.reg safe?
No antivirus engine detected this long-established registry file, and available external intelligence contains no malware family, rule, or known-bad reference.
None of 74 antivirus engines flagged the file, including 17 tier-1 engines, and it has been known since 2018. Available external intelligence also found no matching malware record or YARA rule, although no runtime analysis was completed to validate the registry changes.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
None of 74 antivirus engines flagged the file, including 17 tier-1 engines, and it has been known since 2018. Available external intelligence also found no matching malware record or YARA rule, although no runtime analysis was completed to validate the registry changes.
The strongest evidence is the complete absence of detections across 74 antivirus engines, with all 17 reporting tier-1 engines finding nothing. The sample has existed for more than eight years and has nine recorded submissions, reducing concern that it is an unrecognized new threat. MalwareBazaar, CIRCL, and YARAify provide no corroborating malware intelligence. Code signing is not meaningful for this registry-file format, so its absence does not count against it. No sandbox execution or complete contacted-host check is available, so the conclusion rests primarily on static scanning and historical evidence.
What We Detected
None of 74 antivirus engines flagged the 648-byte registry file. All 17 reporting tier-1 engines, including Avast, BitDefender, ESET-NOD32, Kaspersky, and Microsoft, returned no detection. The file has also been known since 2018, and no matching malware record or YARA rule was found in the available external intelligence.
Threat Behavior
No completed sandbox observation is available, so the exact registry keys and values applied by importing the file were not dynamically verified. A complete contacted-host reputation result is also unavailable, although registry files normally contain configuration data rather than directly executing network activity.
What To Do Now
Before importing any registry file, open it in a text editor and confirm that its keys only affect the intended lock-screen policy or setting. Create a restore point or export the affected registry branch first, and keep endpoint protection enabled.
Where this verdict could be wrong2 caveats
- behaviour=null, so no completed runtime observation confirms what registry changes occur when the file is imported.
- contactedHosts=null, meaning no complete contacted-host reputation result is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 antivirus engines detected malware or suspicious content.
- 17 tier-1 engines reported no detection.
- The sample has been known since 2018.
- MalwareBazaar, CIRCL, and YARAify returned no hits.
- No brand mismatch or adversarial input indicators were detected.
- No completed runtime observation is available.
- The actual registry keys and values were not included in the evidence.
- No complete contacted-host reputation cross-check is available.
Review the registry contents before importing and back up the affected keys or create a restore point. Keep antivirus and endpoint protection enabled.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open it only when its sender or download source is one you independently trust.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
