Some users have encountered a failed fast startup issue in Windows 10 and 8.1. When that issue arises, the Fast Startup mode fails. Events Viewer logs that issue with a 0xc00000d4 error code. One user described this issue in a Microsoft forum post as follows:

I have been facing this issue for a while now. While Fast Startup is enabled, my laptop has very rarely fast startup, and when checking the Events Viewer, it would always state the following:
(error) Event 29, Kernel boot: Windows failed fast startup with error status 0xC00000D4.

What is Windows’ Fast Startup mode?

Fast Startup is a feature available in Windows 10, 8.1, and 8 that quite simply makes your PC start quicker. It does that by saving system states to a hibernation file when you shut down Windows.

Then a full system initialization sequence isn’t needed during startup, which makes Windows start faster.

What are the causes for fast startup error 0xc00000d4?

However, the Fast Startup mode doesn’t always work ok. Error 0xc00000d4 is just one Fast Startup mode issue that more typically arises on PCs with SSD (solid-state drive) storage. This issue can arise for the following reasons:

  • System file corruption: A PC crash might have corrupted some system files.
  • External hardware devices: Error 0xc00000d4 can arise because of external hardware devices connected with your PC, such as external USB storage drives.
  • System changes: Recent Windows 10 system changes made by updates can also feasibly cause error 0xc00000d4.

The most obvious way to resolve error 0xc00000d4 is simply to disable Fast Startup. That solution will stop the error from occurring, but it won’t fix the Fast Startup mode. Thus, some users might prefer to try and fix Fast Startup mode with these potential resolutions first.

How can I fix error 0xc00000d4?

1. Run a system file scan

  1. First, click either the magnifying glass or search box on Windows 10’s taskbar to bring up a search tool.
  2. Next, type Command Prompt in the search box.
  3. Right-click the Command Prompt search result to select Run as administrator.
  4. Now input this Deployment Image command and press Enter: DISM.exe /Online /Cleanup-image /Restorehealth
  5. Then type in this System File Checker command: sfc /scannow
  6. Press the Return keyboard key to run the System File Checker scan.
    sfc scan windows failed fast startup with error status 0xc00000d4
  7. Wait for the scan’s verification to reach 100 percent complete. Then you can read the scan’s outcome in the Command Prompt.

Alternatively, you can give a try to Restoro that will scan your PC and automatically repair any error associated with broken registry files, missing DLLs or malware.

2. Disconnect non-essential external hardware devices

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

If you have any external hardware connected with your PC (hard drives, gamepads, USB sticks, etc), disconnect those devices. Make sure just the mouse is plugged into the PC when you start it.

Thereafter, check Events Viewer to see if error 0xc00000d4 arises without any peripherals connected.

3. Run the Startup Repair Tool

  1. Click Start on the left side of the taskbar.
  2. Select Power on the Start menu to bring up shut down options.
  3. Click Restart while holding the Shift key at the same time. Thereafter, your desktop or laptop should restart at the blue menu shown directly below.
    Choose an option menu windows failed fast startup with error status 0xc00000d4
  4. Select the Troubleshoot option.
  5. Then select the Advanced options button to bring up the menu in the screenshot directly below.

  6. Press the Startup Repair button.
  7. Next, select a user account for which to utilize the Startup Repair tool.
  8. Then input the account password, and click Next to proceed.

4. Roll Windows back to a restore point

  1. Press the Windows keyboard key and X simultaneously to open the quick menu, which includes various shortcuts.
  2. Click Run to open that accessory’s window.
  3. To open System Restore, type the following text in the Open box and click OK: rstrui
  4. Select the Choose a different restore point option, and click Next to continue.

  5. Then click the Show more restore points checkbox to select that option if it’s available.
    System restore points list windows failed fast startup with error status 0xc00000d4
  6. Choose a restore point that will roll Windows 10 back to a date that predates error 0xc00000d4 on your desktop or laptop. If you’re not sure what one to choose, just select the restore point that goes the furthest back.
  7. Select the Next option to continue.
  8. Press the Finish button to confirm the chosen restore point.

Note: Restoring Windows 10 to a previous time will remove software installed on your PC after the system restores the point’s date. Thus, you might need to reinstall the software after rolling back Windows 10. To check what software a restore point removes, click Scan for affected programs in System Restore.

How to disable Fast Startup

  1. If none of those potential resolutions fix the issue, you might have to settle for disabling Fast Startup instead. It’s recommended that users with PCs that include SSDs disable that feature. This is how you can disable Fast Startup in Windows 10.
  2. First, bring up the search box with the Windows + S keyboard shortcut for it.
  3. Type Control Panel in the Type here to search utility’s text box.
  4. Select the Control Panel search result.
  5. Next, click the Category menu to select Small icons.
  6. Then click Power Options to open the applet shown directly below.

  7. Click Choose what the power buttons do on the left of that Control Panel applet.

  9. Thereafter, uncheck the Turn on fast startup (recommended) option to deselect it.

  10. Press the Save changes button to apply the new setting.

How can I speed up the Windows startup with Fast Startup disabled?

Enabling the Fast Startup option isn’t the only way to make Windows start up quicker. Third-party startup programs also slow down system startup.

Therefore, disabling superfluous startup programs can also make Windows start faster. You can disable third-party startup programs and services as follows.

  1. Right-click Windows 10’s taskbar to select a Task Manager shortcut.
  2. Click the Startup tab in Task Manager.
  3. Then select unneeded startup items on that tab, and click the Disable button. The Startup impact column there tells you what programs have the most impact on the startup time.

  4. To disable third-party services starting with Windows, you’ll need to open Run first by pressing its Windows key + R hotkey.
  5. Type this text in Run’s Open box: msconfig
  6. Click OK to open the System Configuration window for MSConfig.
  7. Select the Services tab in the screenshot directly below.

  8. Make sure you select the Hide all Microsoft services checkbox.
  9. Then you can manually disable third-party services you don’t need by deselecting their checkboxes. To disable all third-party services, press the Disable all button.
  10. Select the Apply option, and click the OK button.
  11. A dialog prompt box will open that includes a Restart option. Click that Restart button.
