Microsoft fixed the bug that made copying large files up to twice as slow in Windows 11 patch KB5022913
Windows 11 should finally get a fix for a bug caused when copying large files. The flaw causes slowdowns when performing the action on larger files, taking twice as long as it should.
- Windows 11 23H2 is already in production, indicates a leak
- The change leaves Windows 11 looking like Windows 2000
The problem has existed since December 2022, but the Microsoft still hadn’t solved it. With the future arrival of Moment update 2, for Windows 11 22H2, the issue will be resolved. So far the update is optional and exclusive to testers, but the company is expected to release it with an update rollout next Tuesday (14th).
Anyone installing the KB5022913 patch should recover the file copy at normal speeds. The Windows Latest site did some testing with the preview version and found the issue resolved.

What caused the slowness?
It’s not clear how big a file needs to be to slow down the transfer, nor how many machines were affected by the disruption. The first reports were made by business users, who deal with large files on a daily basis, although home networks were also slow.
Microsoft didn’t detail the cause, but it was clear that this was a bug unique to Windows 11. Since it took nearly three months for a fix, it can be assumed that this is a complex fix issue.
No issues other than slowness have been reported, so data on affected machines should not be corrupted or lost. Even so, it’s a good idea to make a backup before installing the patch to ensure data integrity.
Moment 2 is expected to fix other bugs, such as File Explorer errors and Bluetooth keyboard pairing, as well as bring new expected features. Linking to mobile support with iOS devices should be one of the most celebrated introductions as it will benefit iPhone owners. However, it is expected that the upgrade pin Bing with ChatGPT permanently to the system tray.
