When Win7 copying files, it appears: "You need permission to perform the operation!" (The ultimate solution!)

Then copy the following content to Notepad:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT*shell unas]
@="Acquire the administrator's ownership"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT*shell unascommand]
