Sync programs (Eg: OneDrive or Google Drive) cause file naming bug
There is a bug in Windows 10 when renaming files and I believe it is being caused by OneDrive or any other sync platform. This problem has been present for at least a year. It's difficult to describe this issue, but basically in Windows 10, if you want to rename a file without replacing the entire file name, you double click the file name or hit F2. Then you click within the file name to deselect the name so that you can make partial edits. However, Windows 10 reselects the entire file name again a second later. With OneDrive closed, this issue isn't present.
