Another problem was found in the Windows 11 22H2 operating system. This time it’s about file copy speed. Ned Pyle, the company’s chief program manager, explained this. Apparently, the process slows down when copying large files from a remote computer or server to a Windows 11 computer.

When copying several gigabytes of files, the speedometer dropped 40%, especially on the Windows 11 22H2 system. According to Pyle, this could be related to the operation of the SMB network protocol, which is the most likely scenario so far. However, the same was recorded even when copying local files to the computer itself.

The company is still looking for the cause of the problem, currently unknown. As for users, it is recommended to use the robocopy or xcopy utilities with the /J option to copy files. In this case, everything works as it should. An example code looks like this:

robocopy someserversomeshare c:somefolder somefile.ned /J

You can also use other copy utilities such as TeraCopy, FastCopy or CopyMaestro depending on the environment.

This is not the first issue in Windows 11 22H2. Earlier, it was reported about malfunctions of printers.
