Windows Update Issues
What are windows updates and software notifications?
Updates are additions to software that can help prevent or fix problems, improve how your computer works, or enhance your computing experience.
Software notifications will periodically let you know about new programs that can enhance your experiences with your computer and the Internet. You can choose to receive detailed notification messages letting you know when a new program is available for download and installation. When you get a notification, you can review what's being offered, and get more details. You can install the programs if you like what you see. The notification will appear for a limited time, and you can close it if you're not interested.
What are the different types of updates?
Security updates. A broadly released fix for a product-specific security-related vulnerability. Security vulnerabilities are rated based on their severity, which is indicated in the Microsoft security bulletin as critical, important, moderate, or low.
Critical updates. A broadly released fix for a specific problem addressing a critical, non-security related bug.
Service Packs. A tested, cumulative set of hotfixes, security updates, critical updates, and updates, as well as additional fixes for problems found internally since the release of the product. Service Packs might also contain a limited number of customer-requested design changes or features.
