When software (software) is running on a computer, most of it is loaded into the device’s memory. And if we update the software on the hard drive or SSD, due to the changes made, the software will no longer be able to find the files in the memory that were there a minute ago. This is because the version of the software in memory is incompatible with the version on the hard drive or SSD. As a result, even the computer may fail.
To prevent this from happening, operating systems often offer to restart the computer after installing major software updates. This way, you can prevent errors from appearing when running after the update.
