One of the most annoying thing about Windows is the damn updates and what it might do to your PC. I do realize that they do some good but I feel like all their work is patchwork and not really fixing. Whenever I download I go through and customize the installation and read what exactly each install is going to do.
After all that it always asks you to reboot and sometimes after a little while it restarts on its own. To defeat this feature of Windows update just download Auto Reboot Remover to disable it completely. You can reboot on your own terms, after you have saved everything. Its simple and does the job!
