When you delete a file, create a new folder etc the screen does not update until
you press F5 (for refresh) or close/open the folder. You can automate this
Hive: HKEY_LOCAL_MACHINE
Key: SYSTEM\CurrentControlSet\Control\Update
Name:
UpdateMode
Type: REG_DWORD
Value: 0
This change is immediate and the next time you start Explorer the new auto
update will be in effect.
