This week, Microsoft updated the Windows 11 Insider builds. The Beta channel build, among other things, corrected high CPU utilisation and provided additional OneDrive notifications. A VPN status, new Taskbar search styles, and other new features were all included in the Dev channel version 25252, which was also feature-rich.
Along with adding additional capabilities, Windows 11 22H2’s critical fault that led to a pronounced slowness while copying large files remotely is been fixed in the Dev version 25252. This is fantastic news because many people have been whining and getting frustrated about this persistent glitch. According to the release note outlining this fix:
Unexpectedly delayed network-to-local copying for some users (for instance, while copying a file from a network share) has been fixed.
Ned Pyle, the Principal Program Manager in the Microsoft Windows Server High Availability and Storage group, later confirmed that the problem was in the kernel and had “nothing to do with SMB or compression,” despite the initial suspicion that it was connected to the Server Message Block (SMB) protocol. As a result, local file copy rates were also compromised. Additionally, some users complained that the performance hit was far worse than first believed.
Pyle reaffirmed that the problem was unrelated to SMB and that the remedy should be released later as a cumulative update for all customers. They claim:
After this is verified, the permanent production fix will be included in a regular monthly cumulative update. As I’ve previously stated, the fix is not in SMB, and as I don’t own the component, I don’t have any additional information on timing.
Microsoft has made other improvements recently in addition to the file copy issue. The business has fixed the bug(s) that were affecting Windows 11’s 2022 update’s gaming performance.
