June 2025 Windows 11 Update Errors – Complete Guide for Troubleshooting

Introduction

The June 2025 Windows 11 updates have brought new features, security improvements, and refinements. However, shortly after release, many users worldwide have encountered unexpected issues during or after installing the updates.

Are you seeing sudden app crashes? Update installation failures? Blue screens?

You’re not alone.

In this guide, we will walk you through the most common errors reported after the June 2025 updates, explain why they happen, and offer step-by-step solutions that anyone can follow—even if you’re not a tech expert.

What Happened in the June 2025 Updates?

The major updates in June 2025 include several cumulative and optional preview patches. Some key updates are:

• KB5039302 (Preview Update)
• Security patches and vulnerability fixes
• Improvements to Windows Copilot, Start Menu, and Explorer
• USB and Bluetooth compatibility refinements
• Kernel-level security enforcement updates

While these updates are designed to improve stability and security, they have unintentionally caused system instability for certain users depending on hardware, drivers, and specific configurations.

Common Errors Reported After the June 2025 Updates

Here’s a summary of the main issues users are encountering:

👉 These problems are not universal but tend to appear under specific hardware and driver combinations. Early reports show a higher occurrence on certain manufacturer models or custom-built PCs.

Devices and Configurations Prone to Issues

Some hardware environments seem to be more prone to these issues:

• Fujitsu, NEC, Dell, GIGABYTE (Japan and Asia-Pacific markets)
• Custom-built PCs with GIGABYTE or ASRock motherboards
• Intel 12th Gen and newer CPUs
• Overclocked systems or XMP-enabled memory profiles
• Older drivers that haven’t been updated for a while
• Extensive use of USB or Bluetooth peripherals

Note: These are patterns based on public reports; not all devices within these categories are affected.

Likely Causes Behind the Errors

The errors seem to stem from multiple contributing factors:

• Driver compatibility issues with newer kernel-level security
• Secure Boot or BIOS setting conflicts
• System file corruption during update processes
• Missing or outdated Visual C++ runtime components
• Memory hardware instability or physical RAM defects

Microsoft continues to refine updates, but given the wide variety of PC configurations worldwide, occasional incompatibilities are inevitable.

Solution 1: Repair System Files

First, check and repair system files using these built-in tools:

1．Open Command Prompt as Administrator

2．Run:

3．After completion, run:

These commands repair missing or corrupted system files and restore Windows to a stable state.

Solution 2: Update or Roll Back Device Drivers

Drivers play a critical role in these update-related errors.

• Update drivers for graphics (NVIDIA, AMD, Intel), chipset, network adapters, USB, and Bluetooth.
• If the problem started after a recent driver update, roll back to the previous version.

👉 Keeping drivers up-to-date—but not always the absolute newest beta version—is often the safest practice.

Solution 3: Check Physical Memory (RAM)

RAM issues can cause instability, especially after security updates that enforce stricter memory protection.

• Search for “Windows Memory Diagnostic” in the Start Menu
• Reboot and allow the tool to scan your memory
• If errors are found, consider replacing faulty RAM modules

Solution 4: Review BIOS Settings

BIOS (UEFI) configurations can contribute to instability post-update.

• Disable overclocking temporarily to rule out instability
• Turn off XMP profiles for RAM temporarily
• Check if your BIOS version is outdated and update via the manufacturer’s website following official instructions

👉 Proceed carefully with BIOS updates; follow your device manufacturer’s guidelines.

Additional Workarounds and Tips

Visual C++ Redistributables Reinstallation

Some application crashes (especially 0xc0000005) may be caused by missing or outdated Visual C++ runtime libraries.

• Download and install all supported versions (2005 through 2022) from Microsoft’s official site.
• It’s safe to have multiple versions installed simultaneously.

Disable DEP for Specific Apps

Data Execution Prevention (DEP) sometimes conflicts with older applications.

• Go to: System Properties → Performance → Data Execution Prevention
• Add specific apps as exceptions (avoid disabling DEP entirely)

Pause Windows Update Temporarily

If issues persist:

• Go to Settings → Windows Update → Pause updates
• Wait for additional patches or fixes from Microsoft before retrying

Should You Uninstall KB5039302?

Since KB5039302 is a preview update, uninstalling it is safe if you are experiencing severe problems.

• Go to Settings → Windows Update → Update history → Uninstall updates
• Remove KB5039302 and restart

Often, Microsoft addresses issues in the following month’s cumulative update based on user feedback.

Additional Workarounds & Hidden Tips

Try Installing Updates in Safe Mode

If you repeatedly fail to install the June 2025 updates under normal conditions, try applying updates while booted into Safe Mode.

Safe Mode disables most drivers and background services, which can help prevent conflicts during the update process.

• Go to Settings → System → Recovery → Advanced Startup → Restart now, and select Safe Mode.

• Once in Safe Mode, retry the Windows Update installation.

Use Standalone Installer from Microsoft Update Catalog

If Windows Update consistently fails, consider manually downloading the update package directly from the Microsoft Update Catalog and installing it offline.

• This method often works better after running SFC and DISM repairs.

• Manually installing the KB package can bypass some background conflicts that cause automatic updates to fail.

Check Windows Update Logs for Deeper Diagnosis

For more advanced troubleshooting, checking Windows update logs can reveal specific error details:

• C:\Windows\Logs\CBS\CBS.log

• C:\Windows\WindowsUpdate.log

Even if you’re not familiar with reading these logs, you can share them with technical support or community forums to get more targeted assistance.

Summary Table

Windows update errors like these are understandably frustrating, but they’re not uncommon given the incredible variety of devices running Windows worldwide. If you methodically work through these troubleshooting steps, most issues can be resolved without requiring drastic measures. Stay calm, take one step at a time, and you’ll likely find your system stabilized soon.
