Knowing what service pack or major update your version of Windows is running at is important because you need to know that you have the latest available security updates and features installed.

Service packs and other updates improve the stability, and sometimes the functionality, of Windows. Making sure you have the latest updates installed ensures that Windows, and the software you run on Windows, is working to its fullest.

You can see what service pack or major update you have installed in most versions of Windows via Control Panel. However, the specific way you go about accessing the area in Control Panel where you can view this information depends on which operating system you have.

If you're not sure which version of Windows you're using, see What Version of Windows Do I Have? so you know which set of steps to follow along with below.

Note: If you're using Windows 10 or Windows 8, you'll notice that you don't have a service pack installed. This is because with these versions of Windows, Microsoft releases updates on a continual basis in smaller chunks instead of infrequent and in large packs like is the case with the other Windows versions.

Tip: You can always install the latest Windows service pack or update automatically via Windows Update. Or, if you're needing a service pack for Windows 7 or earlier versions of Windows, you can do so manually via the links we keep updated here: Latest Microsoft Windows Service Packs & Updates.

What Windows 10 Major Update Is Installed?

You can find basic Windows 10 information in the System section of Control Panel but the specific version number of Windows 10 (like you see in the image above) is found in Settings:

Tip: A much faster way to skip through these first three steps to find the Windows 10 version number is through the winver command, which you can invoke in Command Prompt or the Run dialog box.

  1. Open Settings in Windows 10 with the Windows Key + I keyboard combination. Note that that's an uppercase "i" and not an "L."
  2. When the Windows Settings screen opens, choose System.
  3. From the left pane, click or tap About at the bottom.
  4. The Windows 10 major update you have installed is shown on the Version line.
  5. The latest major update to Windows 10 is Windows 10 Version 1709.

    Windows 10 updates can be had automatically through Windows Update.

What Windows 8 Major Update Is Installed?

  1. Open Control Panel. The fastest way to open Control Panel in Windows 8 is to select it through the Power User Menu (Windows Key + X).
  2. Click or tap System and Security.

    Note: You won't see this option if you're viewing Control Panel in the Large icons or Small icons view. Instead, select System and then skip down to Step 4.
  3. Click/tap System.
  4. At the top of the System window, under the Windows edition section, is where the Windows 8 major update version is listed.
  5. The latest major update to Windows 8 is Windows 8.1 Update.

    If you're still running Windows 8 or Windows 8.1, it's recommended to update to the latest Windows 8 version via Windows Update. If you don't want the most up-to-date Windows 8 version to be installed automatically, you can instead download Windows 8.1 Update manually here.

    If you are running Windows 8.1 Update, subsequent updates and new features, if there are any, are released on Patch Tuesday.

    What Windows 7 Service Pack Is Installed?

    1. Open Control Panel. The fastest way to do this in Windows 7 is to click on Start and then Control Panel.

      Tip: In a hurry? Type system in the search box after clicking the Start button. Choose System under Control Panel from the list of results and then skip to Step 4.

    2. Click on the System and Security link.

      Note: If you're viewing the Large icons or Small icons view of Control Panel, you won't see this link. Simply open the System icon and proceed to Step 4.

    3. Click on the System link.

    4. In the Windows edition area of the System window you'll find your Windows 7 edition information, Microsoft's copyright information, and also the service pack level.

      Take a look at the screenshot on this page for an idea of what you should see.

      Note: If you don't have any service pack installed (as in my example), you won't see "Service Pack 0" or "Service Pack None" - you just won't see anything at all.

    1. The latest Windows 7 service pack is Service Pack 1 (SP1).

      If you find that Windows 7 SP1 is not installed, I recommend that you do so as soon as possible, via Windows Update or manually via the correct download here.

      Note: Windows 7 service packs are cumulative. In other words, you only need to install the latest Windows 7 service pack available because it contains the patches and other updates for all previous service packs as well. For example, if the latest Windows 7 service pack is SP3 but you don't have any installed, you do not need to install SP1, then SP2, then SP3 - just SP3 is fine.

    What Windows Vista Service Pack Is Installed?

    1. Open Control Panel by clicking on Start and then on Control Panel.

      Tip: Skip the next few steps by typing system in the search box after clicking Start. Then choose System from the list of results and then move on to Step 4.

    2. Click on the System and Maintenance link.

      Note: If you're viewing the Classic View of Control Panel, you won't see the System and Maintenance link. Instead, double-click on the System icon and proceed to Step 4.

    3. Click on the System link.

    4. In the Windows edition area of the View basic information about your computer window you'll find see information about your version of Windows Vista, followed by the service pack that's installed. See the screenshot on this page for an idea of what you're looking for.

      Note: If you don't have a Windows Vista service pack installed then you won't see anything at all. Unfortunately, Windows Vista doesn't specifically note it when you don't have a service pack installed.

    1. The latest Windows Vista service pack is Service Pack 2 (SP2).

      If you don't have Windows Vista SP2 installed, or don't have a service pack installed at all, then you should do so as soon as you can.

      You can install Windows Vista SP2 automatically from Windows Update or manually by downloading it via the correct link here.

    What Windows XP Service Pack Is Installed?

    1. Open Control Panel through Start and then Control Panel.

    2. Click on the Performance and Maintenance link.

      Note: If you're viewing the Classic View of Control Panel, you won't see this link. Simply double-click on the System icon and proceed to Step 4.

    3. In the Performance and Maintenance window, click on the System Control Panel icon at the bottom of the window.

    4. When the System Properties window opens it should default to the General tab. If not, choose it manually.

    5. In the System: area of the General tab you'll find the operating system version and the service pack level. See the screen shot on this page for an idea of what you're looking for.

      Note: If you don't have any service pack installed, you won't see "Service Pack 0" or "Service Pack None" - there will be no reference to a service pack at all.

    6. The latest Windows XP service pack is Service Pack 3 (SP3).

      If you only have SP1 or SP2 installed, I highly recommend that you install Windows XP SP3 immediately, either via Windows Update or manually via the correct link here.

      Important: If you only have Windows XP SP1, or if you have no Windows XP service pack installed at all, you must first install Windows XP SP1a before installing Windows XP SP3.
