If Windows starts, run DISM and sfc /scannow, then chkdsk C: /scan, update storage and chipset drivers, and uninstall the most recent update or app. If it won't boot, use Troubleshoot → Advanced options for Startup Repair, System Restore or Uninstall Updates.

What CRITICAL_PROCESS_DIED means

CRITICAL_PROCESS_DIED doesn’t point at a driver the way many stop codes do. It says that a core Windows process terminated. Windows can’t continue without it, so it stops.

The process usually dies because its files are corrupted, the storage it’s reading from is failing, or a driver or security tool interfered with it. That is why system-file repair, disk checks and undoing recent changes are the main fixes.

How it shows up

  • Blue screen: “Stop code: CRITICAL_PROCESS_DIED”.
  • Crash during startup, sign-in or shortly after.
  • May follow a Windows update, a sudden power loss or a new driver.

Common causes

  • Corrupted Windows system files.
  • Failing SSD/HDD or file-system errors.
  • Faulty storage, chipset or security drivers.
  • A failed or incomplete Windows update.

How to fix it, step by step

  1. Repair system filesFix damaged Windows files with the DISM and SFC commands below. From recovery, use sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows in Command Prompt.
  2. Check the diskRun chkdsk C: /f (schedule it and restart) and check the drive's health with the maker's tool. Back up immediately if the drive reports problems.
  3. Update storage and chipset driversInstall the latest chipset/storage (Intel RST, AMD chipset, NVMe) drivers and SSD firmware.
  4. Undo recent changesUninstall the latest update (Settings → Windows Update → Update history → Uninstall updates) or use System Restore to a point before the crashes.
  5. Use recovery if it won't bootInterrupt startup three times to open Windows Recovery, then try Startup Repair, System Restore or Uninstall Updates. Can't stay in Windows long enough? Hold Shift and click Restart, then go to Troubleshoot → Advanced options → Startup Settings → Restart and press 4 for Safe Mode.
  6. Reset Windows as a last resortSettings → System → Recovery → Reset this PC → Keep my files reinstalls Windows while keeping personal files.

Command

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Run in an elevated Command Prompt (Run as administrator). DISM can take 10–20 minutes; run sfc after it finishes, then restart.

How to confirm the fix: Windows starts and runs without crashing, and SFC reports no integrity violations on a second run.

Keeping it from coming back

Use a UPS or avoid hard power-offs during updates, keep backups, and watch drive health warnings.
