Folder View Does not Refresh with Windows 7
Many people are reporting Windows 7 does is not refreshing the folder view when changes are made such as adding or renaming a file or folder. Hitting the F5 key forces a refresh and immediately updates the view. There are dozens of suggestions scattered about the internet to change this setting or that setting which in many cases seems to resolve the problem. After reviewing many of these the common solution seems to be to enable or disable any folder option under Computer | Organize | Folder and Search Options | View | any setting
such as “Show hidden files, folders, and drives” and apply. You may need to log off and back on.
This is not a proper solution to the problem, nor does it explain why the problem occurs, but it does seem to resolve the problem in a large number of cases.
