OK, after some research I think that I got a few more clues.
Loggin out before shutting down is a workaround that has been
mentioned, but I would rather find a solution that allows me to
shutdown in a single step.
I am currently testing the system with the first of the following
applied:
KB 182086: http://support.microsoft.com/support/kb/articles/Q182/0/86.ASP
Set the value to "1" in:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management
KB 146092: http://support.microsoft.com/support/kb/articles/Q146/0/92.asp
Set the value to "20,000" [ms] in:
HKLM\SYSTEM\CurrentControlSet\Control\WaitToKillServiceTimeout
Shutdown seems to take forever (I have 1GB RAM), but once I select
"Start|Shut down", I go to sleep and leave the system do its course
until it shuts itself down. So far so good...
Still, I would like to find a more elegant solution - if such one
exists.
In the meanwhile, I have been wondering (perhaps an expert can answer
this):
If write caching was never enabled, why did I experience the problem
in the first place? Could it be that the "write caching" in Device
Manager refers to the one provided by the OS, while the on-disk 8MB
cache is another cache which the OS has no control over?
Thanks,
Sam
