What is creating the hex folders (hex names in curly braces) that are piling up in my user's appdata/local folder?

I am running Windows 7 on a recently bought HP PC (AIO-200-Quad).  I only have one user name defined on this PC.  I have one printer installed, plus Windows Live Mail, IE8, and Office 2010 H&S, and Norton Internet Security 2011.

The appdata/local folder for that user keeps getting new hex folder names (Long names containing Hex digits and dashes, surrounded by curly braces) created in it.  From 1 to 3 folders are created each day since the day after this PC was first powered up.  All of these folders are empty.  I haven't been able to directly correlate it to any specific activity that I'm doing yet, although there is some evidence that Norton scanning for spam e-mails is one of the culprits.

What application(s) or OS function(s) are creating these folders?  Can something be set so they are deleted when they are no longer needed? (Disk Cleanup does not delete them)  Are they safe to delete directly via Windows Explorer?

These folders are created by Windows Live Essentials programs. There is not fix yet.

I did a VB Script to clean this mess.

Enjoy it.

E.F.

Copy and paste into a VBS file.

'Script to clean bug folder - Windows Live Essentials Programs.
Dim oShell
Set oShell = CreateObject( "WScript.Shell" )
strLOCALAPPDATA=oShell.ExpandEnvironmentStrings("%LOCALAPPDATA%")
Dim objFSO
Set objFSO = CreateObject("Scripting.FileSystemObject")
Dim objFolderSource
Dim objFolders
Dim objFolder
Set objFolderSource = objFSO.GetFolder(strLOCALAPPDATA)
Set objFolders = objFolderSource.SubFolders
For Each objFolder in objFolders
If Left(objFolder.Name,1) = "{" Then
If objFolder.Files.Count = 0 And objFolder.SubFolders.Count = 0 Then
objFSO.DeleteFolder objFolderSource & "\" & objFolder.Name
End If
End If
Next
Set objFolderSource = Nothing
Set objFolders = Nothing
Set objFolder = Nothing
Set objFSO = Nothing
Set oShell = Nothing

I think you'll find that at least some of these folders are created each time Windows Live Setup performs its twice-daily version check. You can compare the timestamps on the folders with the log files created at the same time at %localappdata%\Microsoft\WLSetup\Logs.

The product team say (via PM) that the folders are supposed to be deleted when setup is finished, and if they aren't, it might be because AV software has a lock on them. I don't believe that.

So long as they're empty, they can safely be deleted.
