Every month Microsoft distributes critical security updates for Windows computers. If you have Windows Update configured to automatically install these updates, it will do so. Unless something goes wrong. Your computer may have been offline. Something may have interrupted the process. You may already have a virus that prevents updates.
Here's how to check that a specific update is installed:
- Go to Control Panel > Add or Remove Programs.
- Check the box Show Updates.
- Scroll down to find the update you want to verify.
Everything Microsoft does is affiliated with a Knowledge Base article. When the techie community writes about a bug in Windows, they say "this is related to the flaw in KB123456." If an article says "you're toast without update KB123456," you need to check your updates. You can find out more by browsing to support.microsoft.com and searching on the KB number. Maybe you'll find it only applies to some esoteric program you never use anyway, so you don't have to worry.
