Operating system and software patches and updatesThere is no such thing as perfect software. Programs often have compatibility issues or vulnerabilities that compromise your computer's security. Software patches, updates, and drivers are made available, often for free, to consumers to help keep a software program and operating systems running properly and securely. A program with no method of checking for updates requires you to verify the program is up-to-date. Often this can be done by visiting the website of the developer who created the program.
