How To Solve Error Code 0xC0000278

There are several troubleshooting steps you can take to address this error:

Run System File Checker

Open Command Prompt as an administrator by right-clicking on the Start menu and selecting Command Prompt (Admin). Then, type the following command and press Enter:

sfc /scannow

This utility scans for corrupted system files and attempts to repair them.

Check RAM Modules

Use a memory diagnostic tool like Windows Memory Diagnostic to test your RAM modules for errors. Access it by typing "Windows Memory Diagnostic" in the Search bar and pressing Enter. Follow the on-screen instructions to run the scan.

Update Drivers

Ensure all device drivers are up to date. You can update drivers through Device Manager: right-click on the Start menu, select Device Manager, expand the relevant categories (e.g., Display adapters), right-click on the specific device, and choose "Update driver".

Check Hard Drive Health

Use a tool like CHKDSK to scan your hard drive for errors: open Command Prompt as an administrator and type:

chkdsk c: /f /r Replace "c:" with the letter of your system drive. This command checks the disk for errors and attempts to repair them. Consider using a third-party tool like CrystalDiskInfo for more detailed hard drive diagnostics.

Run Startup Repair

Insert your Windows installation media (USB or DVD) and boot from it. Access the Advanced troubleshooting options and select "Startup Repair". This feature automatically detects and fixes potential startup problems.

Perform System Restore

If the error recently started, you can attempt a system restore to revert your computer to a previous state when it was working correctly. Access System Restore through the Control Panel.

Reset Windows

As a last resort, consider resetting Windows to its factory settings. This will erase all data on your hard drive, so be sure to back up important files beforehand. You can access this option through the "Recovery" settings in Windows.

Remember to consult Microsoft's support documentation for additional troubleshooting steps and guidance specific to your Windows version.
