Create Value: Right-click in the right pane, select New > DWORD (32-bit) Value, and name it EnablePeriodicBackup. Set Value: Double-click it and set the value data to 1.

Restart: After rebooting, Windows will again populate the \System32\config\RegBack folder. 2. Manual Backup via Task Scheduler

Once the registry key above is set, you can force a backup immediately:

Step-by-Step Solutions to Fix "RegBack Copy Not Working"

Let’s move from the simplest to the most effective solutions. Do not skip steps.

Solution 5: Check Volume Shadow Copy Service

If your RegBack folder never generates anything (even after enabling periodic backup), the Shadow Copy service might be broken.

  1. Open Services.msc.
  2. Ensure Volume Shadow Copy is running (Startup Type: Manual).
  3. Run vssadmin list writers in an admin CMD. Ensure no writers are reporting errors.
  4. If errors exist, run sfc /scannow followed by DISM /Online /Cleanup-Image /RestoreHealth.
