I found the below problem on another forum and it explains the problem probably better than I could. I have the exact same problem as described, 30 seconds to a minute to create a new folder in Windows 7 Explorer, and then the same thing again after entering the name of the folder. I've also had the 'Refresh' problem described below. I have not tried using Command Line. All updates are installed. I'm running an HP Pavilion p6230f with Windows 7 x64, and 8 GB of RAM.
Any idea why this is happening?
I've been experiencing this very annoying behavior for awhile now where Explorer will hang for several seconds (sometimes as much as a minute or two) when creating new folders, renaming existing folders, and copying/moving files into a new folder. I noticed that similar issues were reported by a couple of other people, and tried the solutions they suggested (disabling any non-Microsoft shell extensions, disabling Windows Search, disabling AntiVirus, running chkdsk /r), but none of them have helped. Perhaps related to this, Windows Explorer has also been slow to pick up on changes when adding/deleting files in a directory, to the point where it's necessary to manually hit "Refresh" (or go up one level in the filesystem, and then back into the folder) to see the changes.
One other interesting thing I noticed is that these same operations all work normally if I use a command line to do them instead of the Windows Explorer application. From the command line I can create/rename directories and manipulate files just fine, and when I do it that way the changes are picked up in Windows Explorer almost instantly, without me needing to hit "Refresh" or otherwise force them to show up.

I also have several other systems (2 desktops, 1 laptop) that are still running the RC build of Windows 7, and they have never encountered this problem.
