How to Find Which Windows Service Pack or Update You Have Installed

Windows 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 well and is secure from malicious attacks.

How to Tell Which Windows Service Pack Is Installed

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

Start by determining your version of Windows, so you know which set of steps to follow along with below. If you're using Windows 11, Windows 10, or Windows 8, you'll notice that you don't have a service pack installed. This is because, with these Windows versions, Microsoft releases updates on a continual basis in smaller chunks instead of infrequent, large packs as was the case with earlier versions.

Windows 11 & 10

You can find basic Windows information in the System section of Settings (W11) or Control Panel (W10), but the specific version number of Windows is found in Settings:

1. Open Settings by pressing the WIN+i key combination.

2. Select System when the Settings screen opens.

3. Choose About from the right side at the bottom (Windows 11), or the left pane at the bottom (Windows 10).

4. The major update you have installed is shown on the Version line.

Windows 11 and Windows 10 updates can be easily installed through Windows Update.

Windows 8, 7, Vista, and XP

The System area of Control Panel is where you can find this information for Windows 8, Windows 7, Windows Vista, and Windows XP.

1. Open Control Panel. The fastest method in Windows 8 is to select it through the Power User Menu (Windows Key+X). For other versions, open the Start menu and select Control Panel.

2. Select System and Security (8 and 7), System and Maintenance (Vista), or Performance and Maintenance (XP).

   You won't see this option if you're viewing Control Panel in the large icons, small icons, or classic views. Instead, select System and then skip down to Step 4.

3. Choose System.

4. At the top of the System window, under the Windows edition section, is the Windows major update version or service pack level.

   On Windows XP, from the General tab, look for the service pack details at the top, under System.

Things to Remember

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 the Windows 8.1 update manually.

The same is true for Windows 7, Vista, and XP: Windows 7 SP1, Vista SP2, and XP SP3 are the latest major updates for those operating systems, so you should update to them if you're not already.
