This isn’t the first time Windows 11 updates have caused problems. Recently, users of Samsung Galaxy Book 4 and other Samsung devices have reported significant access issues following the February 2026 security updates. Specifically, users have encountered the error message “C:\ is not accessible – Access denied” after installing these updates, which has raised concerns among the affected user base.

The issue primarily affects devices running Windows 11 versions 25H2 and 24H2, with reports coming in from regions including Brazil, Portugal, South Korea, and India. Microsoft is currently investigating the matter in collaboration with Samsung, but as of now, no official fix has been provided. The exact root cause of the C:\ drive access problem remains unconfirmed, leaving users in a state of uncertainty.

In addition to the access issues, users have also reported crashes and freezes linked to the KB5079473 update. Microsoft has stated that the issue is not directly caused by Windows updates but is related to Samsung software, particularly the Samsung Galaxy Connect application. This has led to the temporary removal of the Galaxy Connect app from the Microsoft Store to prevent further complications.

Microsoft has advised users against utilizing unofficial workarounds that have surfaced online, as these may compromise Windows’ built-in security protections. A spokesperson for the company emphasized, “Microsoft strongly advises against using this workaround as it weakens Windows’ built-in security protections.” This caution underscores the importance of maintaining system integrity while addressing the current issues.

As users continue to face difficulties, the focus remains on the Samsung Share application, which may be linked to the C:\ drive access problem. However, the exact relationship has yet to be confirmed. The situation has prompted widespread concern among users, particularly those who rely on their Samsung devices for daily tasks.

Microsoft has not yet confirmed a widespread issue with the KB5079473 update, but the company typically monitors feedback after each update release. Observers are keenly watching how the situation unfolds, especially as Microsoft works with Samsung to understand the issue better and prevent similar problems in the future.

As of now, the timeline for when a resolution might be available is unclear. Users are left to navigate these challenges while awaiting further updates from both Microsoft and Samsung. The ongoing investigation aims to provide clarity and restore functionality for affected users as quickly as possible.
