Check Kaspersky Windows Version Support

This guide shows you how to confirm that your version of Windows is compatible with your Kaspersky product before you install or update it. You’ll learn where to find the official compatibility information, how to check your Windows version, and what to do if your system isn’t listed.

What You’ll Need

Your Windows version (find it in Settings > System > About, or by pressing Win + R, typing winver, and pressing Enter).
Your Kaspersky product name (e.g., Kaspersky Standard, Plus, Premium, or a standalone product like Kaspersky Anti-Virus).
Internet access to open the Kaspersky support website.

Step-by-Step

Identify your exact Windows version. Press Win + R, type winver, and press Enter. A small dialog shows the Windows edition and version number (e.g., Windows 11 Pro, version 23H2). Write this down.
Open the Kaspersky support website. Go to support.kaspersky.com in your browser. This is the official support portal.
Find the system requirements for your product. Use the search bar on the support site. Type your product name followed by “system requirements” (e.g., “Kaspersky Standard system requirements”). The first result should be an official Kaspersky support article.
Open the system requirements article. Look for a page titled something like “System requirements for Kaspersky Standard” or “Technical support for Kaspersky applications.” These pages list all supported Windows versions.
Compare your Windows version to the list. The article will list supported versions, e.g., “Windows 11 Home/Pro/Enterprise,” “Windows 10 (versions 21H2, 22H2, 23H2),” etc. Check whether your exact Windows version (from step 1) appears. Note that both the edition (Home, Pro) and the version number (22H2, 23H2) matter.
Check for any special notes. Some products may have exceptions, such as “not supported on Windows 10 LTSC” or “requires a minimum build number.” Read the footnotes carefully.
If your version is listed, you’re good. You can proceed with installation or update. If it’s not listed, your Windows version is likely unsupported.

Common Mistakes

Mixing up Windows edition and version. “Windows 10” is the edition, but “22H2” is the version. Both must be supported. For example, a product may support Windows 10 but only versions 21H2 and later.
Relying on third-party websites. Only the official Kaspersky support site has accurate, up-to-date compatibility data. Other sites may be outdated or incorrect.
Ignoring the difference between 32-bit and 64-bit. Some older Kaspersky products only support 64-bit Windows. Check the system requirements for architecture support.
Assuming all Kaspersky products have the same requirements. Kaspersky Standard, Plus, Premium, and standalone tools (like Kaspersky VPN Secure Connection) each have their own system requirements. Always check for your specific product.

Tips

Keep your Windows updated. Even if your current version is supported, older builds may lose support over time. Kaspersky typically supports the latest Windows feature updates within a few months.
If you’re about to buy a new computer, check the system requirements before purchasing to ensure future compatibility.
Bookmark the system requirements page for your product so you can quickly re-check after Windows updates.
If you’re using Windows 11, note that Kaspersky generally supports the latest version and the two most recent feature updates, similar to Microsoft’s own support policy.

Troubleshooting

Your Windows version is not listed. This means Kaspersky does not officially support it. You have a few options:

Update Windows. If your version is older (e.g., Windows 10 21H2), update to a newer supported version via Windows Update. Once updated, re-check the requirements.
Use Windows built-in protection. If you cannot update, Microsoft Defender Antivirus is a built-in alternative that works on all supported Windows versions.
Contact Kaspersky support. In rare cases, a product may work on an unlisted version, but it’s not guaranteed. Ask support for clarification.

The support page won’t load. Try a different browser or clear your cache. If the site is down, you can also check the Kaspersky forum, which often mirrors system requirements.

You can’t find your product name. Open the Kaspersky application, go to Settings > General > About (or similar), and note the exact product name and version. Search using that exact name.

Frequently Asked Questions

Does Kaspersky support Windows 11 version 24H2?

Yes, Kaspersky products released after October 2024 generally support Windows 11 24H2. Always check the current system requirements for your specific product, as older builds may not be listed.

My Windows 10 is version 1809. Can I install Kaspersky?

Probably not. Kaspersky dropped support for Windows 10 versions older than 21H2 in recent product versions. You’ll need to update Windows 10 to at least version 21H2 or consider upgrading to Windows 11.

Does Kaspersky support Windows 10 LTSC?

Some Kaspersky products support Windows 10 Enterprise LTSC, but not all. Check the system requirements for your specific product. For example, Kaspersky Endpoint Security for Windows supports LTSC versions, but consumer products may not.

Is 32-bit Windows supported?

Most current Kaspersky consumer products are 64-bit only. If you have 32-bit Windows, you may only be able to use older versions, which are no longer updated. Check the system requirements for your product to confirm.

What if I’m using a Windows Insider Preview build?

Kaspersky generally does not support Insider Preview builds. They recommend using stable, released versions of Windows. If you use a preview build, you may encounter compatibility issues.

My Windows version is supported, but the installation fails. What now?

First, ensure your Windows is fully updated. Then, uninstall any previous Kaspersky product using the official removal tool. Restart your PC and try again. If it still fails, contact Kaspersky support with your product version and Windows build number.
