After the recent issue affecting some Galaxy Book laptops, Microsoft confirmed that some Windows 11 users were suddenly unable to access their “C” drive. The company has also identified the likely cause and temporarily removed Samsung’s Galaxy Connect app from the Microsoft Store.

Microsoft pulls Samsung Galaxy Connect from the store temporarily

First spotted by BleepingComputer, Microsoft Store recently removed the Galaxy Connect app to prevent the problem from spreading across more devices. According to an official statement from Microsoft, affected users started seeing an error message saying “C:\ is not accessible – Access denied.” This error prevented them from opening files or launching common applications.

It mainly blocked users from accessing their C: drive, which is the main storage location for Windows system files and applications. In some cases, the issue also stopped administrative actions such as uninstalling updates or collecting system logs. This occurred due to permission failures.

Samsung Galaxy Connect is a tool designed to connect Galaxy phones and Samsung PCs for features like screen mirroring, file sharing, and data transfer. It was the main culprit of the problem. Because the C: drive typically contains Windows and installed apps, the bug created major problems. Users reported being unable to open programs like Outlook, Office apps, web browsers, and even some system utilities. 

Only certain Samsung Galaxy Book models were affected

The bug mostly impacted specific Samsung devices running Windows 11, including several Galaxy Book 4 laptops and Samsung desktop models. Microsoft said the problem appeared after reports of app failures and file access issues on those devices. Examples of affected models include:

• NP750XGJ
• NP750XGL
• NP754XGJ
• NP754XFG
• NP754XGK
• DM500SGA
• DM500TDA
• DM500TGA
• DM501SGA

Microsoft removed the app to prevent more problems

After investigating the issue with Samsung, Microsoft pulled the app from the Microsoft Store to stop more users from installing the problematic version. Also, Samsung has reportedly republished an earlier stable version of the app. This aims to prevent the issue from spreading further. Meanwhile, both companies are still working on solutions for devices that have already experienced the problem.

For now, Microsoft recommends avoiding the affected version of the Galaxy Connect app and keeping Windows and Samsung software fully updated.
