Error: Windows 11 22H2 Bug: Windows 11 2202 Update Slowing File Transfer

Some customers may experience difficulties installing the Windows 11 2022 update when copying large files via SMB. When customers copy large files from remote computers to their PCs, replication performance suffers, according to Microsoft, who confirmed this problem. The business added that it could also be present when copying data to a local drive.

Microsoft warns that copying large files of many gigabytes (GB) in size may take longer than anticipated to complete on Windows 11, version 22H2. "Local file copy may also be affected," the statement reads. "You are more likely to experience this issue copying files to Windows 11, version 22H2 from a network share using Server Message Block (SMB)."

Users allege that system performance has decreased by 40%, while others assert that file copies take twice as long to complete as they should. However, Microsoft's Principal Program Manager for Windows Server Engineering Group noted that depending on the user's equipment and living situation, this can differ from one user to the next.

Although the firm claims to be working on a fix for its upcoming version, Microsoft has still not offered a long-term fix for this problem. Users can test out Microsoft's suggested solutions in the meanwhile.

Method 3: Revert Windows 11 (22H2) to the Previous State to Get Rid of Large File Transfer Slow Issue

As challenging as it might appear, rolling back a Windows feature update is relatively simple. Every time you apply a significant update, Windows 11 makes a backup of your system files and keeps it on your computer for ten days so you can revert to Windows 11 previous version. You only have a limited time to complete it because the files are erased after 10 days.

Also, remember that you can erase these files using the Disk Cleanup tool or the Settings app to get rid of temporary files, so try to wait until the ten days have gone before utilizing these programs.

If the old files are still present on your computer, you can roll back to Windows 11 version 22H2 by simply following these instructions: 

Step 1. You might wish to make a backup of your files before you begin. Although they shouldn't vanish, it's usually safer to be safe.

Step 2. Launch the Settings app. To discover it, use Windows Search, enter the Start menu, and select Settings.

Step 3. Click Recovery after scrolling down to the System section, which automatically opens.

Step 4. Click on 'Go back.' The temporary files for rolling back are no longer available if it is grayed out.

Step 5. When prompted, check any practical reasons for wanting to roll back, then click Next.

Step 6. You must select No, thanks when prompted to determine whether you want to check for updates before rolling back. After reading the following two cautions, click Next, and your computer will restart to start rolling things back.

Step 7. Depending on how quick your computer is, the process could take some time, but for the majority of PCs, it should just take a few minutes. You'll need to sign in using the password you used to upgrade to Windows 11 version 22H2 after it's finished (if you were using one).

This method will help you move to an earlier build but you should still stay with 22H1 until Microsoft fixes this bug.

Method 4. Compress and Transfer Large Files on Windows 11

Zipped (compressed) files are smaller in size and transfer faster to other computers than uncompressed files. To share a collection of files more conveniently, combine them into a single zipped folder. To do that, follow the steps given below:

Step 1. Find the folder or files you wish to zip.

Step 2. Holding down the Shift key while clicking the files or folder will allow you to select the Compressed (zipped) folder from the 'Send to' menu.

Your compressed folder is ready to be transferred! Now send it to the destination location and un-compress it to access your files.
