Now, the user specified "portable install," which means the installation isn't on the system and can be run from a USB drive or similar. I need to outline the steps for a portable installation. Let me think about the typical process for portable software. Usually, you extract the files, maybe there's a setup.bat or similar script. Since it's KMSAuto, there might be no installer, just a standalone executable.
But wait, since KMSAuto is a key generator and activation tool, it's important to remind the user that using it without a valid license is against Microsoft's policy. So I must include a disclaimer at the beginning.
After extraction, there's likely an executable file. The user just needs to run that. But KMSAuto might offer options like activating Windows or Office. The portable version should have all necessary components included.
Then, the activation process itself: selecting the product, applying KMS activation. Maybe there's a button to activate. Then confirming success.
Also, there might be alternative methods like using a legal KMS server if they have a volume license. I should suggest that as a proper method instead of using pirated tools.
Also, note that Microsoft provides volume activation methods for legitimate use. Users with a valid VLK can set up a KMS server and activate their own systems, which is the correct approach.
