If you have used Kmsauto and wish to switch to a legitimate activation, the first step is to uninstall any Kmsauto-related software from your system. Next, you should acquire a genuine product key from an authorized Microsoft reseller or directly from Microsoft. Once you have the key, you can enter it through the Windows or Office activation settings to validate your software. It’s also a good idea to run a full system scan with reputable antivirus software to ensure that no residual malware from the Kmsauto tool remains on your computer.
