Shutting down your PC every now and again is essential. I hear many times how often people leave their computers switched on when they leave the office, this is usually because it takes time to come back on again. It’s not only a fire hazard leaving your computer on, but it’s also a security risk. It stops your computer installing vital security patches, as many need a reboot and process to complete the installation. There is nothing worse than Windows deciding it wants to update in the middle of a working day, you also find this refreshes the operating system and associated data it will feel better for it. If your computer is updating, don’t try shutting down your PC and force it off because you want to go home, just leave it to it as it could cost you hours of downtime if they get corrupted for any reason.
