Kevin:
I would think that you would be able to update your shell since its a file
in use like any other system file.
This is what I do... I have DUA in TD setup to not run at start and
everything in the poll date/time table is unchecked. At boot time the DUA
Service starts but does nothing.
When I want to install a QFE for example I have a bat file that does the
install. This install copies the dup file to the place that DUA is looking
based on my TD configuration. I then run a reg file that tells DUA to run:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DUAgent\Parameters\Con
fig]
"RunOnStart"=dword:00000001
Now, to actually get DUA to run and install the contents of the dup file I
stop then restart the DUA Service via:
net stop "device update agent"
net start "device update agent"
For updating a file in use, this is a snippet from a dus file from one of my
QFE updates:
MOVEFILE,0,1,C:\dua\working\gdi32.dll,1,C:\Windows\System32\gdi32.dll,DAMOVE
FILE_DELAY_UNTIL_REBOOT|DAMOVEFILE_REPLACE_EXISTING
Also, you don't mention EWF. If you use EWF then this gets a little more
complicated.
