Being a Windows expert doesn't mean you have to memorize every shortcut and secret. You just have to know where to find those details when you need them.
That's the point of this page, where I've collected the links I regularly use to find information and download tools and utilities. These include essential information, troubleshooting tools, and download sites, as well as some of my most popular FAQ pages and tips.
Here's everything you need to know before you repair, reinstall, or upgrade Windows 10, including details about activation and product keys.
If you've spent years mastering the ins and outs of Windows Update, prepare to do some unlearning. Windows 10, with its emphasis on "Windows as a service," rewrites almost all the rules of updates and upgrades. Here's what you need to know.
Microsoft's much-hyped free upgrade offer for Windows 10 ended in 2016, and the extension officially expired at the end of 2017. But you can still get a free digital license using these instructions.
You've got a new PC running Windows 10 Home. You want to upgrade to Windows 10 Pro. Here's how to get that upgrade for free. All you need is a Pro/Ultimate product key from an older version of Windows.

Windows 10 release history (official)
Use this Microsoft-provided list to look up the availability date, OS build, and latest revision date for all currently supported Windows 10 versions. Scroll down for availability dates and links to KB articles for all cumulative updates.
Always check this page before installing a new feature update manually. It lists the current status of the latest release and provides details about known issues, including those that Microsoft has designated as serious enough to block installation on affected devices. The page is updated regularly as issues are identified, investigated, and resolved.
With each new Windows 10 version, Microsoft adds a new page with version-specific information about new features in that release. The list focuses mostly on features that are of interest to professionals who support Windows in the enterprise: security, deployment, update, and management.
With each new Windows 10 version, Microsoft publishes a marketing-focused blog post highlighting a few new features. If you want a more detailed list of changes, you'll find them in an unlikely place: The Windows Insider Program archive captures details about each new feature, often with an explanation of why it was implemented the way it was. When a release leaves the Insider program and goes to general release, these notes are all archived under the "What was new" heading.
Each new version includes a long list of new features, but it typically also marks the end of the road for some features, which can be removed, replaced, retired, or deprecated. The two lists of features here includes "Features we're no longer developing" and "Features we removed."
