How to Update Windows (and Fix Updates That Won't Install)

Install Windows updates, set active hours so updates don't interrupt you, and fix common problems like low disk space and stuck or failed updates.

Illustration: How to Update Windows (and Fix Updates That Won't Install)

The short answer

Select Start › Settings › Windows Update, then select Check for updates and install what's available. Restart when asked. If an update won't install, free up disk space, restart and try again, and run the troubleshooter in Settings › System › Troubleshoot › Other troubleshooters › Windows Update.

Windows updates fix security holes, improve stability and update drivers. Windows installs most updates automatically, but it’s worth knowing how to check, schedule and troubleshoot them.

Install updates

  1. Select Start › Settings › Windows Update.
  2. Select Check for updates.
  3. If updates are available, select Download & install (or Install all).
  4. Restart when prompted. Save your work first.

Choose when Windows restarts

  • Active hours: in Settings › Windows Update › Advanced options › Active hours, set the hours you usually use your PC. Windows avoids automatic restarts during that time.
  • Pause updates: select Pause for 1 week on the Windows Update page if you need a short break, but don’t pause for long. Security updates matter.

If an update won’t install

Free up disk space

Updates need free space to download and install. Go to Settings › System › Storage and clean up temporary files, or turn on Storage Sense. See how to free up disk space on Windows.

Restart and try again

Restart your PC, then return to Windows Update and select Check for updates.

Run the troubleshooter

On Windows 11, go to Settings › System › Troubleshoot › Other troubleshooters, and next to Windows Update, select Run. (Newer versions may direct you to the Get Help app instead.)

Disconnect extra devices

Unplug external drives, docks and other hardware you don’t need, then try again. A device driver can sometimes block an update.

Check your connection

Make sure you’re connected to a reliable network, and avoid metered connections, which can limit downloads.

Update other Microsoft products

In Settings › Windows Update › Advanced options, turn on Receive updates for other Microsoft products to keep apps like Microsoft Office up to date too.

Before big updates

Back up your files first. See how to back up your Windows PC.

Before big updates, back up your Windows PC. If updates fail because the drive is full, see how to free up disk space on Windows.

The bottom line

Check Settings › Windows Update regularly, set Active hours so restarts happen at convenient times, and free up disk space if updates fail. Keeping Windows updated is one of the best things you can do for both speed and security.

Frequently asked questions

Can I stop Windows from restarting while I'm working?

Yes. In Settings › Windows Update › Advanced options, set Active hours to when you usually use your PC. Windows avoids restarting during that time. You can also pause updates for a short period.

What are optional updates?

Optional updates include some driver updates and previews of upcoming features. Install driver updates if you have a problem with a specific device; otherwise, regular updates are enough.

My PC runs Windows 10. Will it still get updates?

Microsoft ended support for Windows 10 on October 14, 2025. After that date, Windows 10 no longer receives free security updates, so upgrading to Windows 11 (if your PC supports it) or enrolling in Extended Security Updates is recommended.
