Still don't see it with properly shutting down, noting I've programmed a delay for Windows shutdown, to give BOINC and the system time to write the progress files to storage. Long forgotten, but there's a registry key that can be set, somewhere in the Vista FAQ in Start Here.

Same time, set a multi minute delay [in cc_config] before BOINC can resume computing after a power cycle. Race conditions during a boot is a strong co-suspect cause of tasks resetting.

BTW, who's powering down these days [?], when the non-power consuming ibernation is available, which permits resume without a CPU cycle progress lost.

The misnomer with LAIM understanding is, the OS -will move- portions to disk [VM], if RAM is needed for other applications [when tasks are paused]. With running tasks of course there could develop lots of disk swapping if RAM is in short supply. This is why default settings are to only compute when system is idle... which then requires LAIM to not exit the task app.

Ibernation often needs to be 'activated' somewhere in the Windows settings. Default it's not. Here's the W8 way: http://www.askvg.com/how-to-enable-missing-hi...-in-windows-8-power-menu/

Other than what I provided in fix info, to clarify on your "I have noticed that some CEP tasks stay in memory nonetheless. I will keep track of this.", tasks will be retained in memory until they've completed first checkpoint, regardless if LAIM is on or off. Standard BOINC which cannot be overruled.
