Microsoft’s August 2025 updates have turned into a nightmare for many Windows users. From vanishing SSDs to broken recovery tools, the latest patches are creating serious risks for data loss and system stability. Here’s a clear breakdown of what’s happening, who’s affected, and what you should do right now.
1. SSDs Disappearing or Failing
- Updates KB 5063878 and KB 5062660 are linked to SSD failures under heavy write workloads.
- Drives with Phison NAND controllers appear most affected, though other SSDs and even HDDs have been reported.
- Risk factors include:
- Transfers of 50GB+ at once
- Drives more than 60% full
- In some cases, drives reappear after reboot. In others, data loss is permanent.
2. Recovery Tools Disabled
- Updates, including KB 5063875, broke built-in recovery features such as:
- Reset this PC
- Fix problems using Windows Update
- Affected versions: Windows 10 (22H2, LTSC) and Windows 11 (22H2, 23H2).
- Not affected: Windows 11 24H2.
- On August 19, Microsoft released an out-of-band (OOB) patch (e.g. KB 5066189) to restore functionality.
What You Should Do
If You Use SSDs
- Avoid large file transfers until a fix is confirmed.
- Back up your files immediately using the 3-2-1 rule:
- 3 copies
- 2 different storage types
- 1 copy off-site or in the cloud
- Consider delaying installation of KB 5063878 and KB 5062660.
If Recovery Tools Are Broken
- Go to Settings → Windows Update → Check for Updates.
- Install the out-of-band fix for your version of Windows (e.g. KB 5066189).
- Restart your PC to restore reset/recovery tools.
- If you haven’t updated yet, install only the OOB patch, not the full August update.
Common Questions
Q: Should I uninstall the August 2025 update?
A: If your PC is stable, it’s safer to pause further updates rather than uninstalling. Removing security patches can expose you to vulnerabilities. Instead, back up data and wait for official fixes.
Q: How do I know if my SSD is affected?
A: Most reports involve SSDs using Phison NAND controllers, but other drives have been impacted too. If you notice disappearing drives after file transfers, stop using the system until you back up critical data.
Q: Is Windows 11 24H2 safe?
A: Yes — Windows 11 24H2 has not shown recovery tool issues. However, SSD risks may still apply if the problematic updates are installed.
Q: Can I still reset my PC after installing the OOB patch?
A: Yes. Once you install KB 5066189 (or the patch for your version) and reboot, the Reset and Recovery features should function normally again.
Q: What’s the safest next step if I haven’t updated yet?
A: Install only the OOB patch for recovery, avoid KB 5063878/5062660 for now, and back up your system before making any changes.
Why This Matters
- Without recovery tools, a major system failure could leave your PC unbootable.
- A broken or bricked SSD may mean permanent data loss.
- This update cycle underscores the importance of routine backups and cautious updating.
Final Thoughts
The August 2025 Windows updates are some of the most disruptive in recent memory. With SSD failures and disabled recovery tools, users should take immediate precautions: back up critical data, pause risky updates, and apply Microsoft’s emergency patches where needed. Until Microsoft and SSD vendors issue permanent fixes, treat this update with extreme caution.
