You can easily reinstall Windows 8 on your laptop without reactivation. Download this tool:

http/windows.microsoft.com/en-us/windows-8/create-reset-refresh-media

And use it to create a USB or DVD installer for Windows 8.1. After installation, Windows will automatically activate itself using an OEM signature found in your BIOS.
