Windows 7: Windows 7 freezes when copying large file

Hi all,

I have a really big issue with one of my computer when copying large file (about more than 1GB).



When I copy a large file, 10GB for instance, after the time calcution for copy, the copy begins but the progress bar never goes after 1%. Even if I let the copy working all the night, the status stays the same. I have this issue if I copy a file from a folder to another one or if I copy it from my computer to an external hard drive (both NTFS).

I have another computer with Windows 7 Enterprise which does not have this kind of problem.

Could you help me on this issue?

Thank you very much

Thank you for your answers.

That's true, I uninstalled my antivirus which was AVG Free and now the copy succeeds to finish

BUT, I remark the copies take too much time in this computer with Windows 7, it takes for instance about 4 hours to copy 20 Go ! I solved this issue by installing SuperCopier. Do not hesitate if you have any other suggestions.

Thanks for posting the solution. It helps me know what to recommend to future posters.

Fantastic ! It's something registered by Windows. The patch is downloadable at

You encounter problems when you move data over USB from a Windows 7 or Windows Server 2008 R2-based computer that has an NVIDIA USB EHCI chipset and at least 4GB of RAM
