RawCopy is a open-source console-based tool which copies files using low-level disk access, and so bypasses all the usual restrictions. It doesn't matter whether it's locked by an application, Windows (a Registry hive, maybe, or $MFT), or you just don't have the right permissions: RawCopy ignores all of that and simply copies the file regardless.
To try this out, first open a command prompt as an administrator (right-click cmd.exe, "Run as administrator"). Change to the folder where you've unzipped RawCopy, and enter your copy command in this form:
RawCopy "C:\Source\Folder\File.exe" "C:\Destination\Folder"
Simple? Yes, but there are some rules you need to follow.
Please note that you must specify the full path of the source. A command like RawCopy File.exe "C:\Destination\Folder" wouldn't work, even if you were in C:\Source\Folder already.
The destination can't include a file name, it must be a path only.
If either the source or destination parameters contain spaces then you should surround them with quotes.
If you're running 64-bit Windows then you should use RawCopy64.exe; the program will issue a warning if you forget.
