New Windows 11 bug breaks Samsung PCs, blocking access to C: drive

Windows 11 updates have been causing all kinds of blood-pressure-raising issues over the last several months. That trend continues with the latest February update, with Samsung PCs now experiencing serious issues after installing update KB5077181.

Confirmed by Microsoft as a known issue in Windows 11, the Samsung Galaxy Connect app is causing “loss of access to the C: drive and app failures” on Samsung PCs running Windows 11 25H2 or 24H2. Without access to the C: drive, PCs are effectively inoperable.
