Windows 7 x64 have two explorer.exe

My windows 7 sometimes uses two explorer.exe and then it starting to freeze a lot.
What can I do to have only one explorer.exe?

Hi,
found this:

"Explorer.exe is known to keep crashing in Windows 7 x64. Fortunately, it's really easy to fix it. The problem is that explorer.exe is located in the SysWOW64 directory, but Windows looks for it in Windows\System32. Since there is no explorer.exe there, it keeps crashing. To fix this all you need to do is copy (not move!) explorer.exe from the SysWOW64 folder and paste it into the Windows\System32 folder. That should eliminate the crashes."

I tried to do that, but when I want to copy explore.exe from SysWOW64 to windows it says if I want to overwrite the file, but the file in the windows folder is not the same size as it is in SysWOW64. What should I do?

Do you have a copy of explorer somewhere? Kill one of explorer.exe in taskmanager, if its the wrong one, go to file, new task, write explorer, hit enter

Yes I can to that, but I want solution.

Ups I tried to copy it from SysWOW64 to windows not windows/system32.

Will ty to copy to syste32(there is no explorer.exe ,and see what will happen

I think thats not true. You should allways have only one explorer.exe, no matter what.
Today it showed three instances of explorer.exe

Welcome to Microsoft Answers Forum.
I would suggest you to run online virus scan to see if any virus is causing the problem, Both 32 bit and 64 bit has the same base for its design. No matter how many explorer windows you have opened, it should show only one instance of explorer.exe in task manager, the following link will help you to run online virus scan.
