How often should I reboot the M-Files server machine?

M-Files Server itself does not necessarily require the M-Files server machine to be rebooted, but you should schedule periodic reboots of the server machine because of the added benefit and security of installing Microsoft Windows updates. Keeping a server online without periodic updates and restarts leads to potential vulnerabilities and even failures due to pending operating system updates.

For best practices on scheduling periodic reboots, the article Best Practices with Microsoft Windows Server Update Services provides examples on better control on restarting the server after installing Microsoft Windows updates when avoiding a reboot is not an option.
