Update Browser Browser Update Troubleshooting 2 — Questions and Answers
Question 1: If a browser update causes websites to display incorrectly, what is the quickest first diagnostic step?
- Reinstall the operating system
- Clear the browser cache and cookies (Correct answer)
- Downgrade the browser to the previous version
- Disable JavaScript
Correct answer: Clear the browser cache and cookies
Clearing cache and cookies resolves many post-update display issues caused by conflicts between cached old content and new browser behavior.

- Open Task Manager to check extension memory usage
Correct answer: Open the browser in private/incognito mode (which disables extensions by default) and test the issue
Private/Incognito mode disables most extensions by default, making it an easy way to test if an extension is causing the problem.

Error 4 usually means Chrome couldn't be updated because the browser is still running; closing all Chrome windows often resolves it.

The Services Manager (services.msc) allows you to view, start, stop, and configure Windows services including browser update services.
