Common use of ERUNT is at Start-up.
If the computer crashes with a broken register ten minutes later,
then ERUNT can restore the registry as it was,
and it restarts - and possibly crashes 10 minutes later, Ad Nauseum.
Would it be better to assume that the registry was fine when the computer had been running all day,
and something went wrong during the shut-down/power-up chaos and confusion,
and it would be better to use a registry backup made BEFORE the corruption of the registry ?
That way if the registry is broken on start-up the backup should give you another good day.
Is there any situation in which a backup at shutdown would be worse than a backup at start-up ?
I cannot remember ever needing to use an Erunt backup.
Perhaps that says more about the effectiveness of my memory than the quality of Windows ! !
My principle motivation is that after a BIOS delay I wait for the opportunity to type my password,
and then my desktop appears and lots of start-up stuff happens plus my start-up script that delays A.V. updates whilst the notification tray populates.
Perhaps 15 seconds after typing my password there are enough CPU cycles and disc accesses to spare for loading Firefox and doing what I want to do.
That 15 seconds is stretched out by another 10 of 15 seconds at the start of the day - because of the ERUNT backup creation.
I will avoid that extra 10 or 15 second delay by removing ERUNT from my start-up script when I am most impatient to get going,
and instead launching it from my shutdown script when there is no hurry - I am now the kitchen for a coffee/meal break and the PC can take it's own sweet time.
That is my motivation, but please tell me of any errors in my analysis.
