I saw this first in the 8.1 RT preview (never ran the 8.0 RTM) and had hoped that it would be gone in RTM, but it's still there and now I've experienced it on 8.1 Pro as well.
Essentially, if I'm logged in and running Task Manager and I've changed the settings from their defaults (e.g. I tend to switch to more detail, low refresh and display kernel CPU times) and then, for what ever reason windows shuts down unexpectedly (windows crashes, runs out of battery power, etc, even when already in [connected] standby) then when windows starts up again and I login, Task Manager will have reset it's settings to the defaults.
It doesn't seem to matter if I've successfully rebooted (potentially saving the settings) before the unexpected shutdown/restart. If Task Manager is open at the time, it will lose it's settings.
Anyone else seeing this?
I've got it on my Surface RT 8.1 (Gen 1) and HP Pavilion dv 6 [Recent, clean install of Win 8.1 Pro x64].
Anyone got any ideas on fixing it?
I haven't noticed any other apps/programs forgetting their settings.
