Many of you never switch off your main computer. If so this post is for you.
This is not good practice. What happens is that many of the updates and patches, the computer requires a reboot to complete. If this reboot does not occur weird things happen.
The other problem is memory leaks. What is happening here is that you are building up useless data, chunks, software, etc. in memory. This will slow down the computer and in the worse case can cause parts of the computer to fail e.g. one of your printers no-longer work.
As such it is recommended that all computers, get a restart once a week.
