How to Install Windows 11 Updates & See What Changed

Keeping Windows 11 up to date is essential for security, stability, and access to new features. This guide walks you through installing updates via Windows Update and then shows you how to check the update history to see exactly what was changed on your PC.

What You’ll Need

• A PC running Windows 11 (version 21H2 or later)
• An internet connection (broadband or mobile hotspot)
• Administrator rights on the PC (you’ll need to confirm a User Account Control prompt)
• At least 10–20 GB of free disk space, depending on the update size
• Your PC plugged into power (especially for laptops) to avoid interruptions during installation

Step-by-Step

1. Open Windows Update settings. Press Win + I to open Settings, then click Windows Update in the left sidebar. Alternatively, right-click the Start button and select Settings, then navigate to Windows Update.
2. Check for updates. In the Windows Update page, click the Check for updates button. Windows will scan Microsoft’s servers for available updates, including security patches, driver updates, and optional feature updates.
3. Review what’s being installed. If updates are found, you’ll see a list with names like “2024-10 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems.â€� Click on Download & install (or Install now if already downloaded). Some updates may install automatically without this prompt.
4. Start the installation. Click Install now and wait. Windows will download the update files and then begin installing. You may see a progress bar and a percentage. Depending on the update size, this can take anywhere from a few minutes to over an hour.
5. Restart if prompted. Many updates require a restart to finish. Click Restart now when the prompt appears. If you’re busy, you can schedule the restart for a specific time by clicking Schedule the restart and choosing a time.
6. Wait for the restart cycle. During restart, Windows will show a spinning circle and a message like “Working on updates.� Do not turn off your PC. It may restart several times. Once it boots back to the login screen, the installation is complete.
7. Verify the update was installed. Go back to Settings > Windows Update. You should see a message like “You’re up to dateâ€� or “Updates available.â€� If you see “Updates available,â€� repeat steps 2–6 until no more are offered.
8. Check update history. In the Windows Update page, click Update history. This shows a list of all recent updates, separated into categories: Quality Updates, Driver Updates, Definition Updates, and Other Updates.
9. See what changed. Click on any update to expand it and see a short description. For cumulative updates, you’ll often see a link that says “Learn moreâ€� or a KB number (like KB5031354). Click that link to open Microsoft’s official support page, which lists the specific fixes, improvements, and known issues for that update.
10. Check for feature updates. In Windows Update, click Check for updates again. If a major feature update (like 23H2 or 24H2) is available for your device, it will appear as a separate, larger download. You can click Download & install to get it. Feature updates often bring new interface changes and functionality.

Common Mistakes

• Ignoring the restart prompt. Some updates only apply after a restart. If you keep postponing, the update may not finish installing, and you’ll keep seeing the same update in the list.
• Turning off the PC during installation. This can corrupt the Windows installation. Always let the update process complete, even if it seems stuck.
• Not checking for updates after a failed attempt. If an update fails, Windows will usually retry automatically. But if you manually cancel, you may need to click “Check for updatesâ€� again.
• Confusing “Update historyâ€� with “Installed updates.â€� Update history shows recent installations, while “Installed updatesâ€� (in Control Panel) shows a longer list of all updates ever installed. Both are useful but serve different purposes.
• Skipping optional updates. Optional updates are not installed by default. If you want the latest drivers or feature previews, you need to click “Download & installâ€� on them separately.

Tips

• Set active hours. In Windows Update settings, click Advanced options and then Active hours. This tells Windows when you’re usually using the PC, so it won’t restart during that time.
• Pause updates if needed. If you’re in the middle of important work, you can pause updates for up to 5 weeks (in the Windows Update page, click Pause updates). But don’t pause indefinitely—security updates are critical.
• Use a wired connection. Large updates download faster and more reliably over Ethernet than Wi-Fi.
• Keep your system clean. Use the built-in Disk Cleanup or Storage Sense to free up space before a big update.
• Bookmark the KB page. When you click “Learn moreâ€� for an update, save that page. It’s the official source for what changed.

Troubleshooting

If an update fails to install, you’ll see an error code (like 0x800f081f) in the Windows Update page. Here’s what to do:

• Run the Windows Update troubleshooter. Go to Settings > System > Troubleshoot > Other troubleshooters, then click Run next to “Windows Update.â€� This automated tool can fix common issues like corrupted files.
• Restart your PC and try again. A simple reboot often clears temporary glitches.
• Check disk space. If you’re low on space, the update may fail. Free up space by deleting temp files or moving large files to external storage.
• Use the Windows Update Assistant. If the standard update fails, download the Windows Update Assistant from Microsoft’s official website. It can install the latest feature update manually.
• Reset Windows Update components. Open Command Prompt as administrator and run the following commands one by one: net stop wuauserv, net stop cryptSvc, net stop bits, ren C:\Windows\SoftwareDistribution SoftwareDistribution.old, net start wuauserv, net start cryptSvc, net start bits. Then restart your PC and try updating again.
• Check for known issues. If an update is causing problems (like a blue screen or app crashes), go to the KB page and see if Microsoft lists a known issue and a workaround. You can also uninstall the update via Settings > Windows Update > Update history > Uninstall updates.

Frequently Asked Questions

Q: How long does a Windows 11 update take?
A: Small security updates take 5–15 minutes. Feature updates (like 23H2) can take 30–60 minutes or more, depending on your hardware and internet speed.

Q: Can I use my PC while updates are downloading?
Yes, you can keep working while updates download. Installation usually requires a restart, but you can schedule it for later.

Q: Why does Windows 11 force restart after an update?
Some updates change core system files that are in use while Windows is running. A restart is necessary to apply them safely.

Q: How do I see the exact changes in a specific update?
Click the “Learn more� link next to the update in Update history. It opens the official Microsoft support page (KB article) with a detailed changelog.

Q: What if I don’t want a certain update?
You can hide a specific update using the “Show or hide updatesâ€� troubleshooter tool from Microsoft, but it’s not recommended for security updates. For driver updates, you can use the “Pause updatesâ€� option temporarily.

Q: Do I need to install optional updates?
Optional updates are not required for security, but they can fix bugs or add features. If you’re having a specific issue, installing the relevant optional driver update may help.
