Known Error - WIN 11 slowing down SSD

• Some users who have upgraded from Windows 10 to Windows 11 are experiencing reduced performance with their computers' solid-state drives (SSD). Reddit communities and Microsoft's support forum are filled with complaints of the upgrade affecting SSD write speeds. According to BetaNews, the drop in performance has been verified by benchmark tests like CrystalDiskMark. The results show reduced random write speed approaching 50 percent that of earlier performance with Windows 10 with the same hardware.

• Thankfully there's a very easy fix to this head-scratching problem courtesy of an official patch from Microsoft: the KB5007262 patch. The update will not be automatically pushed out to all the Windows 11 systems – so it'll have to be installed manually. Anyone experiencing the issue with SSD speed can head over to the Microsoft Update Catalog and download the patch. The description of the update says the update patches the issue with NVMe, SSD, and hard drive performance which occurs due to NTFS USN journaling being enabled. Apparently, the USN journal on disk C: is enabled by default.
