How to Update Windows — A Complete Step-by-Step Guide for Windows 10 & 11

📅 Updated: April 2025📖 7 min read🌐 Worldwide audience🔌 Focus keyword: How to update Windows

Here is something most people never think about until something goes wrong — their Windows is out of date. Maybe your computer started running slow. Maybe a new app won’t install. Or maybe you just got a notification that says “Updates are available” and you have been dismissing it for weeks. Sound familiar?

Updating Windows is one of the simplest yet most important things you can do for your computer. It keeps your system secure, fixes annoying bugs, improves performance, and sometimes brings in exciting new features. And the good news? It takes just a few clicks. In this guide, we will walk you through exactly how to update Windows — step by step — whether you are on Windows 10 or Windows 11.

💡Why this matters in 2025 Microsoft ended support for Windows 10 in October 2025. That means no more security updates for Windows 10 unless you upgrade to Windows 11. If you are still on Windows 10, this guide will help you update or upgrade safely.

Why Should You Keep Windows Updated?

Before we jump into the how-to, let us quickly understand why this matters. A lot of people skip updates because they are afraid of something breaking, or they just do not want to deal with the restart. That is completely understandable — but here is the reality:

Every time Microsoft releases an update, it is patching holes that hackers and malware use to get into your system. An unpatched Windows PC is like leaving your front door unlocked. Beyond security, updates also fix software bugs that cause apps to crash, improve how your PC handles memory and battery, and sometimes even add new features like improved taskbar options, new settings, or AI tools built into Windows 11.

The bottom line is simple — updated Windows equals a safer, faster, and more stable computer.

How to Update Windows 11 — Step by Step

If your computer is already running Windows 11, updating it is quick and straightforward. Here is exactly what you need to do:

1. Click the Start button — the Windows icon at the bottom of your screen — and then click Settings (the gear icon).

2. In the Settings window, look at the left sidebar and click Windows Update. It is usually at the very bottom of the list.

3. You will now see the Windows Update page. Click the blue “Check for updates” button. Windows will start scanning for any available updates.

4. If updates are available, you will see them listed on the screen. Click “Download & install” to start the process. Larger updates may take a few minutes to download depending on your internet speed.

5.Once the download is complete, Windows will ask you to Restart your PC to finish installing the update. Click “Restart now” — or schedule a restart for a time that suits you so you do not lose any open work.

6.Your PC will restart and may show a screen saying “Working on updates — please wait.” This is completely normal. Do not turn off your computer during this stage. Once it finishes, you will be taken back to your desktop, fully updated.

✅ Pro tip: Get updates faster In Windows Update settings, toggle on “Get the latest updates as soon as they’re available.” This puts your PC at the front of the queue for new updates, including Windows 11 version 25H2 — the latest 2025 update from Microsoft.

How to Update Windows 10 — Step by Step

Still on Windows 10? No problem. The update process is slightly different but just as simple. Follow these steps:

1. Click the Start button and open Settings (the gear icon on the left side of the Start menu).

2.Click on Update & Security. This section is specifically for Windows Update and other security features.

3.On the left, make sure Windows Update is selected. Then click the “Check for updates” button.

4.Windows will look for available updates. If there are any, click Download and let the process run. You can continue using your PC while updates download in the background.

5.After downloading, you will be prompted to Restart to complete the installation. Choose a restart time that works best for you.

⚠️Important: Windows 10 support ended October 2025 Microsoft stopped providing free security updates for Windows 10 after October 14, 2025. If your PC meets the requirements, we strongly recommend upgrading to Windows 11 for continued protection and new features.

How to Upgrade from Windows 10 to Windows 11

If your PC supports Windows 11, upgrading is free. Microsoft makes it easy to check and upgrade through Windows Update itself. Here is how:

1. First, check if your PC is compatible. Download the free PC Health Check app from Microsoft’s website. It tells you instantly whether your device can run Windows 11.

2. If compatible, open Settings > Update & Security > Windows Update. You may see a banner that says “Windows 11 is ready for your device.”

3. Click “Download and install” under the Windows 11 upgrade option. The download is around 4–6 GB so a stable internet connection helps.

4.Restart your PC when prompted. The upgrade will install automatically and your files, apps, and settings will be preserved.

🔒Back up before upgrading Upgrades are generally safe and preserve your data, but it is always a smart idea to back up your important files to an external drive or OneDrive before any major Windows upgrade — just in case.

The 4 Ways to Update Windows — Compared

There is more than one way to update Windows, and each method works differently depending on your situation. Here is a quick overview to help you pick the right one:

Method	Best For	Difficulty	Notes
Windows Update (Settings)	Most users — everyday updates	Easy	Recommended for all users. Safe and automatic.
Installation Assistant Tool	Upgrading to a new Windows version	Easy	Download from Microsoft site. Guides you step by step.
Media Creation Tool	Multiple PCs or clean install	Medium	Creates a bootable USB. For advanced users.
ISO File Download	Manual / offline installation	Medium	Full Windows image. Best for IT professionals.

For most everyday users at home, the first method — Windows Update inside Settings — is all you will ever need. The others are there for special situations like upgrading a PC that is not receiving updates automatically, or when you are setting up a completely new machine.

Common Windows Update Problems and How to Fix Them

Updates usually run smoothly, but sometimes things do not go as planned. Here are the most common problems people face and how to solve them without needing a technician:

Updates stuck at 0% or not downloading

This usually happens when your internet connection drops mid-download or a previous update did not complete properly. Try restarting your router and your PC, then check for updates again. If the problem continues, run the built-in Windows Update Troubleshooter from Settings > System > Troubleshoot > Other troubleshooters.

Not enough disk space to install updates

Some Windows updates are large and require free space to install. Open File Explorer, right-click your C: drive, and check how much space is available. If it is below 10 GB, use the Disk Cleanup tool (search for it in Start) to free up space before retrying the update.

Update fails and keeps rolling back

If Windows tries to install an update, fails, and automatically rolls back to the previous version, it might mean the update has a compatibility issue with something on your PC. Wait a few days — Microsoft often releases a fix quickly. You can also check the Windows release health page on Microsoft’s website to see if your issue is a known problem.

PC running slow after an update

Occasionally, an update may cause temporary slowness while Windows finishes background tasks like indexing. Give your PC about 30 minutes after a fresh update and restart to settle down. If the slowness continues, check Task Manager (Ctrl + Shift + Esc) to see if any process is using too many resources.

🚫Never turn off your PC during an update Interrupting a Windows update mid-installation can cause serious system errors. Always let the update finish, even if it takes longer than expected. Keep your laptop plugged in to avoid a shutdown due to low battery.

How to Turn On Automatic Updates in Windows

If you want Windows to always stay updated without you having to remember, you can turn on automatic updates. This way, Windows will download and install updates in the background and only ask you to restart when it is convenient.

On Windows 11, go to Settings > Windows Update > Advanced options. Here you can enable “Download updates over metered connections” and set active hours so Windows knows not to restart your PC when you are in the middle of work. On Windows 10, the same settings are available under Settings > Update & Security > Windows Update > Advanced options.

Setting your active hours correctly is the single most useful thing you can do here. Tell Windows you are typically active from 9 AM to 10 PM, for example, and it will always schedule restarts for after that window — so updates happen quietly while you sleep.

Frequently Asked Questions

1 How do I check which version of Windows I have?

Press the Windows key + R on your keyboard, type winver, and press Enter. A small window will pop up showing your exact Windows version and build number. This tells you whether you are on Windows 10, Windows 11, and which specific version like 23H2 or 25H2.

2 Is it safe to update Windows?

Yes, absolutely. Microsoft tests updates thoroughly before releasing them. Very occasionally, a rare update may cause a minor issue on specific hardware — but these are quickly identified and Microsoft releases a fix. The risk of NOT updating is far greater, as your system becomes vulnerable to security threats.

3 What is the latest version of Windows 11 in 2025?

As of late 2025, the latest version is Windows 11 version 25H2, released in September 2025. It includes AI-powered features, an improved Start menu, and enhanced security. You can get it through Windows Update by enabling the “Get the latest updates as soon as they’re available” toggle.

4 Will updating Windows delete my files?

No. Regular Windows updates and even major version upgrades (like going from Windows 10 to Windows 11) do not delete your personal files, photos, documents, or installed apps. However, it is always a good habit to back up important files before any major upgrade just to be safe.

5 How long does a Windows update take?

Small security updates usually take 5 to 15 minutes including restart time. Larger feature updates like version upgrades can take 30 minutes to an hour depending on your PC’s speed and internet connection. Make sure your laptop is plugged in and you have a stable internet connection before starting a big update.

6 Can I pause Windows updates?

Yes. In Windows 11, go to Settings > Windows Update and you will see a “Pause updates” option. You can pause updates for up to 5 weeks. This is useful if you are in the middle of an important project and do not want any unexpected restarts. Just remember to unpause and update soon after — staying unprotected for too long is not ideal.

7 My PC says it is not compatible with Windows 11 — what should I do?

Windows 11 requires specific hardware — including a TPM 2.0 chip, a compatible 64-bit processor, at least 4 GB RAM, and 64 GB of storage. If your PC does not meet these requirements, Microsoft recommends staying on Windows 10 for now or considering purchasing a new PC that supports Windows 11. Do not try unofficial workarounds to force the upgrade as they can cause stability issues.

Final Thoughts — Keep Your Windows Updated, Keep Your PC Protected

Keeping Windows updated is honestly one of the easiest and most impactful things you can do for your computer. It takes just a few clicks and happens mostly in the background. In return, you get a more secure, stable, and capable PC.

Whether you are simply installing the latest monthly patch or making the jump from Windows 10 to Windows 11 version 25H2, the process is designed to be as smooth as possible. Follow the steps in this guide, let the updates run, and your computer will thank you for it.
