Yes, KMSPico can be used on multiple devices, but it’s important to note that each activation only lasts for 180 days unless renewed. If you plan to use KMSPico on different computers, you can run the software on each one, but this may require administrator access. Keep in mind that Microsoft may detect multiple activations from the same KMS server, which could lead to software deactivation or penalties. For ongoing use across multiple devices, it’s advisable to consider legitimate licensing options for stability and compliance.
