Windows BSOD Error 0x00000064 — SYMBOLIC_INITIALIZATION_FAILED Fix

What Does This Error Mean?

The 0x00000064 blue screen means Windows failed to set up the symbolic link objects it needs during early startup. This is called SYMBOLIC_INITIALIZATION_FAILED. It almost always happens at boot time and prevents Windows from starting. Corrupted system files, failed Windows updates, or registry damage are the most common causes.

Affected Models

Windows 10
Windows 11
Windows 8.1
Windows Server 2016

Common Causes

Critical Windows system files that handle object manager initialization have become corrupted
A Windows update failed mid-installation and left the system in a partially updated state
The Windows registry has been damaged, preventing the object manager from creating required symbolic links
A third-party security tool or antivirus has quarantined or deleted Windows system files by mistake
A sudden power loss or hard shutdown during a Windows update corrupted boot-stage system files

How to Fix It

Boot from Windows Recovery Environment. Restart your PC and press F11, F8, or hold Shift while clicking Restart from the login screen. Navigate to Troubleshoot > Advanced Options > Startup Repair.

Startup Repair can automatically detect and fix symbolic initialization failures caused by corrupted or missing system files. Let it run completely — it may take 10 to 15 minutes.
From the Advanced Options menu, open Command Prompt and run System File Checker in offline mode: sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

Running SFC offline (before Windows fully loads) allows it to replace corrupted files that cannot be replaced while Windows is running. Use the drive letter where Windows is actually installed — it may be D: in recovery mode.
Also run DISM from the recovery Command Prompt: DISM /Image:C:\ /Cleanup-Image /RestoreHealth

DISM repairs the Windows component store which SFC uses as its source for replacement files. Running both together is more effective than running either alone.
Try a System Restore. From Advanced Options > System Restore, select a restore point from before the error first appeared.

System Restore is particularly effective when a bad update caused this error. Choose the most recent restore point that predates the problem.
If your antivirus recently flagged and quarantined files, open the antivirus software from a working computer's remote management console or boot into Safe Mode and restore the quarantined items.

Some antivirus programs mistakenly identify legitimate Windows system files as threats. If yours recently moved files to quarantine around the time this error started, restoring them may immediately fix the boot failure.

When to Call a Professional

If Startup Repair and System File Checker both fail to fix this error, the Windows installation may need to be repaired using installation media. A technician can perform an in-place upgrade repair that reinstalls Windows system files without deleting your data. This is a more advanced procedure but is very effective for deeply corrupted Windows installations.

Frequently Asked Questions

What are symbolic links and why does Windows need them at startup?

In Windows, symbolic links are internal pointers that connect one system object to another. For example, a symbolic link might connect a device driver path to the actual hardware object it controls. The object manager sets these up during the very first phase of boot. If it cannot create these links — because required files are missing or corrupted — Windows has no way to proceed and stops immediately.

Can a power outage cause this error?

Yes. If power is lost while Windows is updating or writing important system files, those files can be left in a corrupted or half-written state. When Windows tries to boot next time and finds corrupted initialization files, it crashes with this BSOD. A UPS (Uninterruptible Power Supply) is the best protection against this — it keeps your PC powered during brief outages.

How do I know which drive letter Windows is on in Recovery Mode?

In recovery mode, Windows assigns drive letters differently than during normal operation. To find the right drive, open Command Prompt and type: dir C:\ — if you see Windows files, it is C:. If not, try dir D:\ and so on. Look for a folder named 'Windows' — whichever drive contains it is the one to use in your repair commands.
