How to update a Microsoft Windows computer
Since the introduction of Microsoft Windows 98, Microsoft has greatly improved the way users can update their computer. Below are steps on how to perform these updates, as well as additional recommendations to help update your computer.
Microsoft Windows Update
If you are running Microsoft Windows 98 or later, at least some updates should be available for your computer. In most cases, automatic updates and the latest drivers are available online. To update your software through Windows, follow the steps below.
Note: Users on a corporate network or running an illegal copy of Microsoft Windows may be unable to perform Microsoft Updates. If you are on a corporate network, contact your administrator if you are concerned about updating your computer. If you are running an illegal copy of Microsoft Windows, we recommend you purchase a valid copy of Microsoft Windows to download updates.
Windows Update is automatically turned on in Windows 10 and cannot be turned off for home users. Only enterprise users (Windows 10 for business) can delay the installation of Windows updates.
Windows Vista, Windows 7, Windows 8, Windows 8.1
- Open the Control Panel.
- If using Small icons view, click on the Windows Update option. If using the Category view, click on the System and Security option, then click on the Windows Update option.
- Windows Update will check for any available updates for your computer. If any updates are found, you should be able to view the available updates. It is highly recommended that you first install all important updates and service packs that are available. In some cases, you may only be able to do a few important updates or service pack updates each time, if some updates are dependent on other updates being installed first.
Windows XP and earlier
- Visit http://windowsupdate.microsoft.com.
* For this page to work, you must view it in Internet Explorer.
- On the Microsoft Windows Update page, select the option Scan for updates. If prompted to install a plug-in, click Yes. Not installing this plug-in will prevent you from scanning for updates.
- Because this feature must query your computer, Microsoft will gather information from your computer allowing the software to know what it needs to update. There are several urban legends about Microsoft attempting to inspect your computer for illegal software, install unwanted the programs, and steal your private information. None of the practices are true. Unless otherwise stated in Microsoft's Privacy statement, Microsoft collects information from your computer during this process. Collected information includes:
- After Windows Update has completed scanning, you should be able to view the available updates for your computer. It is highly recommended that you first install all critical updates and service packs that are available. In some cases, you may only be able to do a few critical updates or service pack updates each time.
- Although Microsoft does provide some driver updates for hardware devices, it is important to realize that they will not have all the latest drivers. You may want to consider updating the drivers directly from your computer manufacturer. See the computer drivers page for a listing of computer hardware manufacturers and a link to their drivers page.
Note: Whenever you are prompted to reboot the computer, reboot the computer. Rebooting is an important step and in some cases may be required several times before you have installed all the Windows updates available. After the computer has rebooted, make sure to visit the Windows update page again to make sure all the files you need are downloaded.
Microsoft Windows XP and later users
Users of Microsoft Windows XP and later versions can have Microsoft Windows automatically update their computer.
Other hardware drivers
To get the best performance from your computer, it is recommended that you make sure you have the latest drivers for the hardware devices in your computer.
Unable to view Windows Update page
Below are some reasons why you may be unable to view the Microsoft Windows Update page.
- If you've just installed Windows XP, 2000, or older version of Windows the update page is no longer compatible unless you're running the latest service pack. See KB 2497281 for additional information and links to the appropriate service packs.
- Your time, date, or year on your computer is not set properly. See our page for setting date and time on a computer.
- You are trying to access the Microsoft Windows Update page through a web browser other than Microsoft Internet Explorer.
- If you are on a Corporate Network, your administrators may have disabled this feature. If this is the case, you should receive a message indicating that the Windows Update feature has been disabled.
- You are using an illegal copy of Microsoft Windows.
Every time I run the Windows Update my computer has problems
Although Microsoft tests the updates before they are released with numerous computer configurations, you may have issues after running an update. Usually these problems are caused by other software programs, a unique computer or software configuration, or third-party drivers.
If you have already ran an update and are have a problem not documented try uninstalling the updates through the Add/Remove Programs or Programs and Features in the Control Panel.
Below are recommendations for helping to prevent problems.
- Temporarily disable any virus and spyware protection programs.
- Disable any disk software utilities or performance tools running on the computer.
- Let the updates run without using the computer. Step away from the computer while updates are being installed.
- Clear your Internet History and Cache.
- If you are encountering problems after installing driver updates, we recommend you try updating the drivers from the hardware manufacturer's website instead of through Microsoft. A listing of driver manufacturers can be found on our computer drivers page.
- If the update is not a critical update, do not run the update immediately after it has been released. In some rare cases, Microsoft discovers issues with its updates after they are first released that may cause your computer issues.
Although problems may occur after running the Microsoft Windows Update. It is still highly recommend you always update your software using this valuable service because of the problems and security issues they can fix.
How do I know if my computer has all the Windows updates?
If you're uncertain if your computer has all the Microsoft Windows updates installed on your computer, visit http://windowsupdate.microsoft.com/ and have your computer scanned for any available updates. If no updates are found, your computer is up-to-date.
Alternatively, you can download software utilities such as Belarc Advisor that will list the updates installed on your computer and any critical updates you may be missing.
