It was reported last week that a large number of Windows 11 users were experiencing SSD performance degradation bug. And now Microsoft announced that this problem has been fixed.
Microsoft has released Windows Preview Update KB5007262 for Windows 11, which fixes a number of bugs related to slower write speeds. It turned out that the error concerns only the “C” drive, and it is connected with the functioning of the journal – NTFS USN.
The performance degradation bug has been observed in Windows 11 for several months. It was reported on the Windows Insider program before the release of the OS. The error is significant as it halved the performance of the C drive. Microsoft found the problem and released the KB5007262 update. This update resolves a fairly large number of issues and bugs that annoyed Windows 11 users.
