When you reinstall the operating system, a Kaspersky application is removed from your computer along with the license information. To avoid losing the license and maintain computer protection, we recommend that you connect your application to My Kaspersky before reinstalling the operating system. For instructions, see this article.

If you cannot find the activation code or connect the application to My Kaspersky, see the guide below.

If you have already reinstalled the operating system and lost the license information, see this article for instructions.
