I have the same issue. When selecting multiple files using CTRL, I move the mouse wrong and Windows thinks I want to copy them. I already know how to copy. I don't WANT to copy them or move them. I don't need to know other ways to copy, or other keyboard shortcuts, same as the gentleman who first posted. I may be selecting files to do something to the id tags, if they're music files, or there are a number of other things I might want to do that have no relationship to copying. I merely want to select them. I'm talking about folders that have hundreds of files in them, in which the files I want to select cannot be arranged any way to make the files I want contiguous. If I were looking for all of one file type, or all files created on one particular day, it would be easy to order them to select them without using CTRL. As it is, I usually compromise when manipulating large numbers of files by doing them in small batches, in the hope that I can select a reasonable number before I mess up moving the mouse, and have to undo the copies and then reselect the files. Isn't there some way to disable the default copy? We already have perfectly satisfactory ways to copy things. I had a similar issue one time with accidentally selecting "create shortcut"--which I use maybe once a year--instead of delete from the context menu, not a lot, but often enough that it was an annoyance, and someone came up with a registry fix to remove it. There's got to be a registry key somewhere that you can edit to keep Windows from copying.
