Laptop unable to use BitLocker on drive with VSS service timestamp tampering
4.5
The VSS service detects inconsistent timestamps in its metadata, blocking encryption.
Symptoms
- BitLocker error
- VSS metadata error
- System lag
Possible Causes
- Clock manipulation
- Dual-boot conflicts
- Malware
Step-by-Step Fix
1
Sync System Clock
Ensure Windows Time service is running and synced with an NTP server.
2
Clear VSS Metadata
Run "vssadmin delete shadows /all" to reset the state.
3
Check BIOS Time
Ensure the hardware clock matches the OS time.
When to See a Technician
VSS is extremely sensitive to time; even a few seconds of drift can cause metadata mismatches.
