Windows 11 Moment 2 Will Bring Long-Awaited Fix for File Copy Slowdown Bug

Microsoft’s upcoming Windows 11 Moment 2 update will bring a fix for a file copy slowdown bug that has been ongoing for months.


is putting the final touches to its Windows 11 Moment 2 update, which is due to launch in March. This is a mid-cycle feature update that will add plenty of new tools as well as performance and general improvements. Microsoft will also use the release to fix some long-standing issues, including a file copy slowdown bug.

A persistent bug that has been ongoing since October, some users with 2022 Update are reporting file copy slowdown, usually over a network. Microsoft opened an issue for this problem months ago and initially claimed it was because of a Server Message Block (SMB) protocol flaw.

However, the company later reported that the problem was deeper in the Windows kernel. A patch was set out to the Insider program and more fixes followed. So, Insiders have been able to solve this issue. Although, general users have not.

Microsoft recently rolled out a fix to the Release Preview channel on the Insider Program. This is the update that will become Windows 11 Moment 2. This latest update is Release Preview build 22621.1343 and includes the fix labelled as KB5022913.

In its release notes, Microsoft says the following:

“We fixed an issue that affected copying from a network to a local drive. Copying was slower than expected for some users.”


Windows 11 Moment updates are feature releases that will happen multiple times per year, with one big annual update. Moment 2 is expected in March, while we reported last month that Moment 3 is in development and ready to ship in May. It also emerged that Microsoft is planning a Moment 4 release that will become Windows 11 2023 Update this fall.
