Surface-Laptop-Studio-Windows-11

Earlier this week, we reported on performance issues in Windows 11 that stem from NVMe SSD write speeds. While a Microsoft spokesperson confirmed the issue on social media, no official word came until now. Microsoft has now officially acknowledged the issue and says it is working on a fix.

Windows 11 is facing a new performance problem with users complaining about slower NVMe since the launch of the platform. It seems the issue is varied and not affecting all users, with several drivers showing different symptoms.

Some users have taken to Microsoft’s own forums to complain. For examples, there are some who say they SSD write performance, reducing to around half what it was when running on Windows 10.

One interesting aspect of this problem is Microsoft shipped Windows 11 with the issue. This is a problem users have been facing since early previews of the platform during the summer.

Confirmation

Either way, Microsoft now confirms this issue and has updated the support document for Optional Update KB5007262:

“Addresses an issue that affects the performance of all disks (NVMe, SSD, hardisk) on Windows 11 by performing unnecessary actions each time a write operation occurs. This issue occurs only when the NTFS USN journal is enabled. Note, the USN journal is always enabled on the C: disk.”

Microsoft seems to confirm that the issue affects all drives and not just NVMe SSDs. This means more users may be affected than previously thought. Users can install KB5007262 to see if the fix works.

Despite the company promising massive performance gains from Windows 10, Windows 11 seems to be not quite what Microsoft was offering. The company recently promised it will make improvements to Windows 11 performance, but not until 2022.
