Almost everyone that uses a modern version of Windows is familiar with Windows Update. Maybe you've been right in the middle of your work and gotten a notification that Windows needs to install updates, or turned on your computer only to find that you had to wait for updating to finish. Microsoft regularly issues security patches to prevent your security from being compromised, but Windows 10 users will receive more significant changes to their system twice every year.
In a similar way, Mac users are likely to be familiar with Apple's yearly releases of new MacOS versions. Every year, Apple allows any of its users with compatible hardware to upgrade to the latest version of the operating system. New versions include additional features and support for newer software.
Recently, both Apple and Microsoft have released large updates like this. For Apple, it was 2018's Mojave operating system, while Microsoft released the 2018 Fall Feature Update for Windows 10. Both updates have had their own set of issues since they've launched, introducing bugs, software incompatibilities, and other problems for early adopters. With all of these problems, is it worth it to update your computer?
The simple answer is "not yet." While it is a good idea to upgrade your computer to have the most recent security patches, features, and software support, the risks that are currently come along with it aren't worth it. In the worst case, some Windows users have reported losing all of their user files. These kinds of problems can be costly in terms of data and time, and nobody wants to deal with those kinds of issues around Christmas or New Years.
It's a good practice for ordinary users to wait a couple of months after the release of a major update before installing it themselves. That way, software developers have time to prepare fixes to make sure everything goes smoothly. Given enough time, the issues will be ironed out and you can safely enjoy the new features of your operating system.
