How to Update the Operating System on Windows 11

Install the latest OS version to get security patches and performance fixes.

Last verified: February 21, 2026

Windows Update is the most comprehensive update system of any desktop OS, handling OS patches, security fixes, driver updates, and feature releases through a single interface, though the distinction between quality updates (monthly patches) and feature updates (twice-yearly major releases) matters for planning. Major Windows 11 feature updates can take 30–45 minutes and require a restart, while monthly quality/security updates on a fast machine usually complete in under 15 minutes. The Settings > Windows Update > Pause Updates option lets you delay updates for up to 5 weeks if you need system stability during a critical period, which is preferable to ignoring driver update prompts entirely.

Quick Steps

Follow in order for the fastest result.

  1. 1Go to Settings > Windows Update and click Check for Updates. Install all listed updates and restart when prompted.
  2. 2Connect to Wi-Fi and plug into power before starting a major update.
  3. 3After restart, check Settings > About for the new OS version number to confirm the update was applied.

Frequently Asked Questions

Why is my Windows 11 OS update taking so long?
Major Windows feature updates can be 4–8 GB and require time to download, extract, patch, and restart. On slower HDDs the process can take over an hour. Connect to Wi-Fi, plug in power, and leave the device alone — don't force restart during the update.
Is it safe to use my Windows 11 while an OS update is downloading?
Downloading is safe to continue using the device. The actual installation phase (after download completes) requires restarting and you must not interrupt it. Install updates when you can afford 15–60 minutes of downtime.
What happens if I don't update my Windows 11 OS?
Security vulnerabilities accumulate over time. Operating systems receive regular security patches that close exploits discovered after launch. Running an outdated OS leaves those holes unpatched. After Microsoft or Apple end support for a version, no further patches are issued — at that point the OS becomes genuinely risky for internet use.
Why does my Windows 11 say it's up to date but others have a newer version?
Microsoft staggers Windows updates — some machines receive updates weeks before others. You can force it by going to Windows Update and clicking Check for Updates, or using the Media Creation Tool to install the specific version manually.
