在 Windows 10 推出之前，網上就有人對於免費升級有不同的解讀，有人甚至誤以為 Microsoft 把 Windows 10 變成免費，翻版也可以變正版甚麼甚麼。不過，最終 Microsoft 仍然把 Windows 升級，正版維持正版，盜版維持盜版不變。
正如激活狀態不變，故此在 Windows 8 中使用 Microsoft Toolkit 以 AutoKMS 激活的 Windows 8 或者 Windows 8.1 可以升級至 Windows 10。早前，激活工具 Microsoft Toolkit 2.6 Beta 1 正式推出，同時宣告攻破了 Windows 10 及 Office 2016 的激活系統。
Microsoft Toolkit 2.6 BETA 1 更新内容：
- Office 2016 Support (WARNING: Preliminary – Assumed to work, but may fail if unexpected changes/assumptions about Office install are introduced by Office 2016 RTM).
- Windows 10 Support.
- Added Licensing State message “Store License”. Occurs when getting the free permanent Windows 10 Upgrade.
- Disable KMS Online Ticket Validation (Windows 8.1+) when activating
- Disable Windows Vista Rearm Count (OS doesn’t support it)
- Fixed Backup of Windows Vista due to lack of cache.dat
- Fixed KMS Server Service crash on XP due to corrupt HWID
- Improved TAP Drivers
- Improved WinDivert Uninstall
- Remove Trial and Grace Keys when using EZ-Activator.
- Support for KMS PID with 5 Digit Build Number (EX: 10240).
