I just want to ask about logging out of windows on a domain. We have a user who goes weeks (even months) without logging out of Windows. Does Windows tend to become unstable if it isn’t rebooted or even logged out for that length of time? He has occasional issues with freezing in excel. Tried driver updates, Office updates, Windows updates, disabled hardware acceleration, disabled Live preview, all without fixing the issue. Wondering if never logging off or rebooting would play into it.
