Windows 11 Update Not to Blame for SSD Failures, Says Microsoft

Expert Verified By

Microsoft Is Monitoring Feedback To Investigate Any Future Reports!

Story Highlight
  • Microsoft says that the Windows 11 update isn’t the reason SSDs are getting bricked.
  • Instead, something else is causing it, and they’re investigating reports to monitor it.
  • The previous report claimed that storage devices with a Phison controller are at risk.

Recently, Windows 11 got a new security update that reportedly bricked SSDs and hard drives for some users. The update titled ‘KB5063878’ is the latest security update for the systems, but Microsoft has now denied the allegations. 

In a new statement, Microsoft says that they’ve thoroughly researched and found out that the new Windows 11 security update is not responsible for bricking users’ storage devices, and the reason is something else. 

Why it matters: Since the news broke, fans have been worried that they might run into the same issue if they update their systems, but Microsoft now claims that this won’t be the case.

Microsoft says Windows security update isn’t the reason SSDs are getting bricked.

According to the user who shared the story, the issue occurs if your SSD goes through an extended period of writing. They experienced it themselves while updating Cyberpunk 2077 right after installing the security update.

Now, according to Microsoft, their investigation resulted in no link between the update and storage bricking; instead, it happens due to something else. However, they are still taking feedback and trying to see why it happened.

They’re trying to investigate further to understand the issue.

After thorough investigation, Microsoft has found no connection between the August 2025 Windows security update and the types of hard drive failures reported on social media.

The issue reportedly occurs on SSDs and HDDs with Phison controllers onboard. However, since Microsoft says that the update isn’t causing it, everything becomes trickier because there is no definitive reason anymore
