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.
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. kmsauto net 2015 v140 portable install
So putting it all together: disclaimer, steps for portable install, activation process, warnings, and alternatives. But wait, since KMSAuto is a key generator
Also, compatibility: KMSAuto 2015 might not work on newer Windows versions. If the user is on Windows 10 or later, maybe it's outdated. But the user is asking for KMSAuto Net 2015, so perhaps they have a specific need for that version. I need to outline the steps for a portable installation
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.
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.
Wait, does KMSAuto 2015 v140 have a portable version? Maybe the user is referring to a version where the portable option is part of the download. So maybe after extracting, running the .exe as is is enough. Also, portable usually means no registry changes or installations.
