Comprehensive Guide: Computer Shuts Down Automatically During Windows 10 Version 1803 Installation
Understanding the Windows 10 Version 1803 (April 2018 Update) Shutdown Problem
The Windows 10 version 1803, also known as the April 2018 Update, introduced several new features but also brought significant installation challenges for many users. One of the most frustrating issues reported was computers automatically shutting down during the update process, often without any error messages or clear indicators of what went wrong.
This problem typically manifests in several ways:
- System powers off completely during the “Getting things ready” phase
- Computer restarts unexpectedly at various percentages (commonly between 30-70%)
- Blue screen errors (BSOD) followed by automatic shutdown
- Endless reboot loops after failed installation attempts
Primary Causes of Automatic Shutdown During Update 1803 Installation
1. Insufficient Power Supply
The most common hardware-related cause is an inadequate or failing power supply unit (PSU). The version 1803 update process is particularly demanding on system resources, and many users reported that their systems would shut down when the PSU couldn’t handle the increased power draw during installation.
Key indicators of PSU issues:
- Shutdowns occur at similar progress percentages
- System restarts immediately when power button is pressed
- No error logs in Event Viewer (sudden power loss)
- Other power-related issues (random shutdowns during gaming/stress tests)
2. Driver Incompatibilities
Version 1803 introduced significant changes to the Windows driver model, particularly for:
- Storage controllers (especially older Intel RST drivers)
- GPU drivers (NVIDIA and AMD)
- Network adapters (particularly Killer Networking and some Realtek chips)
- Audio drivers (Creative Sound Blaster, some Realtek versions)
Microsoft documented several known driver conflicts that could cause installation failures and subsequent shutdowns. The most problematic were storage drivers that would cause the system to lose access to the boot volume during the update process.
3. Insufficient Disk Space
While Microsoft officially stated that 20GB of free space was required for the update, many users found that having less than 30GB could lead to installation failures. The update process creates multiple backup points and temporary files that require significant space.
| Component | Microsoft Minimum | Recommended | Optimal |
|---|---|---|---|
| System drive free space | 20GB | 30GB | 50GB+ |
| Recovery partition | 300MB | 500MB | 1GB+ |
| Temp folder space | 5GB | 10GB | 15GB+ |
4. Thermal Issues and Overheating
The intensive update process can push CPUs to 100% utilization for extended periods, particularly during the “Working on updates” phase. Systems with inadequate cooling or accumulated dust in heat sinks may overheat and trigger automatic shutdowns as a protective measure.
5. Corrupted System Files
Pre-existing system file corruption can prevent the update from completing successfully. The Windows Update process attempts to verify system integrity before proceeding, and if critical files are corrupted, it may trigger a shutdown to prevent further damage.
6. Antivirus and Security Software Conflicts
Several third-party antivirus programs were known to interfere with the version 1803 update process, including:
- McAfee (particularly versions before 2018)
- Norton Security (2017 and earlier)
- Avast (specific versions with behavior shield enabled)
- AVG (conflicts with Windows Defender integration)
Step-by-Step Troubleshooting Guide
Phase 1: Pre-Installation Preparation
- Verify System Requirements
- 64-bit processor with at least 2 cores
- 4GB RAM minimum (8GB recommended)
- 64GB storage (20GB free space minimum)
- DirectX 9 compatible GPU with WDDM 1.0 driver
- Check Power Supply Adequacy
- For desktop PCs: Ensure PSU is at least 400W for basic systems, 500W+ for gaming/workstations
- For laptops: Connect to power adapter and ensure battery is charged >50%
- Test with a known-good PSU if available
- Create System Backup
- Use Windows Backup or third-party tools like Macrium Reflect
- Create a system restore point
- Back up important documents to external storage
- Free Up Disk Space
- Run Disk Cleanup (cleanmgr)
- Remove temporary files (%temp% folder)
- Uninstall unused applications
- Consider moving files to external storage
Phase 2: Driver and Software Preparation
- Update Critical Drivers
- Storage controllers (Intel RST, AMD RAID, etc.)
- GPU drivers (use DDU to clean old drivers first)
- Network adapters
- Chipset drivers
- Temporarily Disable Security Software
- Uninstall third-party antivirus (use Windows Defender temporarily)
- Disable firewall temporarily during update
- Disable any VPN or proxy software
- Check for Known Incompatible Software
- Old versions of iTunes
- Certain anti-cheat software (e.g., BattlEye, Easy Anti-Cheat)
- Some disk encryption tools
Phase 3: Alternative Installation Methods
- Use Media Creation Tool
- Download from Microsoft’s official site
- Create bootable USB (8GB+ recommended)
- Select “Upgrade this PC now” option
- Perform Clean Installation
- Backup all data first
- Boot from USB and select “Custom install”
- Format system partition during setup
- Use Windows Update Assistant
- Alternative to Media Creation Tool
- Often better at handling driver conflicts
- Available from Microsoft’s update catalog
Phase 4: Advanced Troubleshooting
- Check Windows Update Logs
- Location: C:\Windows\Logs\CBS\CBS.log
- Look for errors with codes like 0x80070002, 0x80070003, 0x80240020
- Run System File Checker
sfc /scannow dism /online /cleanup-image /restorehealth
- Check Event Viewer
- Look for critical errors in System logs
- Filter for Event ID 6008 (previous shutdown was unexpected)
- Test Hardware Components
- Run memtest86 for RAM testing
- Check SMART status of storage drives
- Monitor temperatures with HWMonitor

Preventive Measures for Future Windows Updates
To avoid similar issues with future Windows updates, consider implementing these proactive measures:
1. Hardware Maintenance
- Replace PSU every 5-7 years for desktop systems
- Clean dust from cooling systems every 6 months
- Monitor hardware temperatures regularly
- Replace thermal paste every 2-3 years
2. Software Preparation
- Keep all drivers updated, especially storage and GPU drivers
- Uninstall outdated or unused software before major updates
- Temporarily disable non-essential startup programs
- Ensure at least 50GB free space before updates
3. Update Strategy
- Wait 2-4 weeks after major update release before installing
- Check Windows release health dashboard for known issues
- Consider using Media Creation Tool instead of Windows Update
- Schedule updates during periods of low system usage
4. Recovery Planning
- Maintain current system backups (weekly recommended)
- Create system restore points before major updates
- Keep Windows installation media available
- Document your system configuration and drivers
