[Solution] Windows Vista Explorer Hangs while Copying Files from External Media

I'm getting numerous e-mails asking for solution of this problem. This problem exists in Windows Vista SP1. The problem occurs when you copy a large file or lots of files from an external media like CD/DVD, flash drives and sometimes from network drives.

In this problem, the explorer window which is being used by the copy process hangs, also the progress dialog box hangs if you try to move it, click on it or if you click somewhere else and returns to it.


Although the explorer window and progress dialog box hang, Windows still keeps continue copying the files and when the copy operation finishes, the explorer window and the progress dialog box become available again.

So if you are also facing this problem, use following simple steps and your problem will be solved:

1. Click on "Start button -> All Programs -> Accessories". Right-click on "Command Prompt" and select "Run As Administrator". If you are prompted to enter password, enter the password and continue. You can also open Command Prompt in Administrator mode by typing "cmd" in Start Menu Search box and press "Ctrl+Shift+Enter".

2. Now provide following command:

bcdedit.exe /set {current} nx AlwaysOff

3. Restart your system and now you should not face any problem while copying files.

  • Hi, thank you for your solution.
    I was trying to copy around 70,000 files from an SD card to a removable USB HD, Vista still frozen during the copying even if I followed your solution. So this doesn't work for me.
