1 device license

[AFT 0]

I have already a license key for 1 device and it is working for my "windows" laptop. But what if I installed a new "WINDOWS" and then set up a new ESET smart security?? Is the license valid for the first "WINDOWS" only? Or I can use the remaining period of the license for the new "windows"??

As long as you keep ESET installed and activated on one computer, it's ok. If you would like to use it on both at the same time, you'd need to extend your license to 2 computers.
