why do computers need to reboot after an update

703 views

I thought more recent OS had ways to update files currently in use and not require reboots.
Corporate policy of rebooting once a week and forcing it is killing me: I usually have tens of excel windows interlinked, and having to reboot daily just saps my will to live….

They don’t always! It depends what was updated.

When you turn on a computer, it has to go through A LOT of steps to get everything ready. One of those steps is to load all the software it needs into memory. A lot of this software is ONLY loaded into memory at this stage, because, for example, it might do something like control delicate/complicated hardware, and reloading or unloading it from memory, even temporarily, could cause it to malfunction.

So if you update software, then how to you activate the updated version? You have to do the thing that causes it to be loaded into memory. If it’s a piece of software that is only loaded when you turn on the computer, that’s what you have to do.
