A few months after the bug was discovered, Microsoft released an update that aims to fix an issue with large file copying speeds in Windows 11. Especially those who work with network drives can benefit from the fix.

Microsoft is releasing an optional update that fixes copy issues in Windows 11. In September last year, a bug became known that in some cases slows down the copy speed in Windows 11 2022. Especially when users want to copy large files from a network drive to their system, this would not work as smoothly as expected. Microsoft itself states that the copy time slows down and users claim that the error sometimes doubles it.

Soon for everyone

KB5022913 should solve this problem. The update is now in preview and has no impact on computer security. Therefore, the administrator has to install the patch manually. Microsoft will integrate the solution in the upcoming Patch Tuesday, so you can wait and see.

The error appears to be related to using the cache manager during a copy job. Until patched, you can work around the problem by copying a command that doesn’t use this cache manager. That’s concrete Robocopy And xcopywhere you enter the command from the command prompt.
