Windows 10: File copy is atrocious since 1909

Hello everyone,


This is getting out of hand so I had to come and ask. I see on different forums that this problem is out there. When I copy a file; particularly a larger file; on an NVME SSD RAID0 array!!! HP EX950; copying starts at 1.5-1.6GB/s for the first couple seconds, and then it drops to a mere 9MB/s and it takes >60seconds to recover to 800-900MB/s just to drop back again to 9MB/s. I formatted the SSDs, tested them separately there and back, the problem is there only on Windows 10. On Unix systems, this is not an issue, copying larger files is smooth around 1.5GB/s from start to finish either in RAID array or distinct drives. On Windows 10 however, it doesn't matter. Copy drops in whatever configuration, whatever drive EX950, 860QVO, 970 EVO plus...

Is a fix planned for this issue?

Java.nio.file - Copying files

You can't copy a folder, thats why it generates an exception (you are trying to copy a folder using a copy file function).
You probably need to list all the files inside that folder and copy one by one

Issue was the above, so thanks temp02.

 

User.000 issue after updating to 1909

I'm one of the many people suffering from issues with user profiles after applying Update 1909 to Windows 10. I've read all the threads I can find on the topic here and have followed the suggestions, all to no avail. Any other thoughts are appreciated.

After applying Update 1909, the ProfileImagePath was changed to c:\users\User.000
One file that was always in use and couldn't be removed was left in c:\users\User (can't recall or find the exact file now), so I could never rename or remove the c:\user\User directory.

I followed the multiple suggestions from Brink and others:

• Rebooted at least 6 times
• Enabled hidden Administrator
• Booted into Safe Mode
• Changed ProfileImagePath
• Tried to rename c:\users\User but couldn't because a file was still in use
• Copied all data from c:\users\User.000 into c:\users\User
• Rebooted and had temporary profile
• Followed steps in Brink tutorial to change ImageProfilePath; rebooted with no change
• Restored using Restore Point from before Update 1909 - returned to single profile state (User.000)
• Removed each update that was installed individually and rebooted after each update removal - profile state never changed
• After all updates were removed, repeated the steps above with hidden Administrator, changing profile, etc. - same issue with file in use in c:\users\User
• Followed all steps above with hidden Administrator but without copying files from User.000 to User - same results

Any suggestions are greatly appreciated!
