KMSAuto may be flagged by antivirus software due to its nature as an activator. This is a false positive. We recommend temporarily disabling your antivirus during download and activation, then re-enabling it afterward. Our files are thoroughly scanned and completely safe.

Expert answers to common KMSAuto questions
KMSAuto stands out with its advanced emulation technology that more accurately replicates Microsoft's official KMS servers. Unlike basic activators, it includes automatic renewal, detailed logging, and support for specialized products like Project and Visio. The software maintains better system stability by avoiding unnecessary file modifications and includes self-repair capabilities for the KMS service.
Yes, KMSAuto 2025 has been specifically updated to maintain compatibility with all Windows 11 feature updates, including the latest 23H2 release. The activation persists through updates because it establishes a permanent KMS client configuration that Microsoft's own update process recognizes as valid. If any issues occur after major updates, simply rerun the activator.
KMSAuto can convert Office 365 subscription installations to volume license versions, effectively making them permanently activated without requiring a subscription. This process doesn't remove any features and actually provides more control over updates. The activation remains valid indefinitely with our automatic renewal feature that refreshes the KMS activation every 180 days.
This common error indicates a KMS communication issue. Follow these steps: (1) Ensure you ran as administrator, (2) Temporarily disable Windows Firewall, (3) Verify system time/date is correct, (4) Run "slmgr /skms 127.0.0.1" in admin Command Prompt, (5) Try the "Advanced Activation" mode in KMSAuto. Most failures result from incomplete preparation steps.
KMSAuto can create a scheduled task that runs silently in the background to renew your activation before the standard 180-day KMS period expires. This feature uses minimal system resources and only activates when needed. You can configure renewal intervals (default is 160 days) through the "Settings" tab in KMSAuto's interface.
KMSAuto activations pass all standard validation checks because they use Microsoft's own KMS protocol exactly as intended. The activation appears identical to enterprise volume licensing. However, for business use, we always recommend proper licensing to ensure compliance during audits.
