What are computer operating system updates? Why do I need them?
Apple and Microsoft frequently release updates for their Operating Systems. You must keep your computer current with these updates to protect against vulnerabilities. Many viruses and worms spread rapidly because this essential task is postponed, putting your data at risk.
NOTE, operating system updates are automatically installed on computers that are managed by the C&IT DeskTech team. You may have to restart the PC afterwards. Learn more in kb.wayne.edu/684 .
