Title : MS Office 2013 / Windows 8 Latest Activator
Microsoft Toolkit - Official KMS Solution for Microsoft Products

This is a set of tools and functions for managing licensing, deploying, and activating Microsoft Office and Windows. All output from these functions is displayed in the Information Console. All functions are run in the background and the GUI is disabled to prevent running multiple functions, as they could conflict or cause damage if run concurrently. The Microsoft Office Setup Customization Functions (Customize Setup Tab), AutoKMS Uninstaller (if AutoKMS is installed), AutoRearm Uninstaller (if AutoRearm is installed), Office Uninstaller and Product Key Checker work even if Microsoft Office or Windows is not installed/supported. For information about individual functions, see the program readme.
Requirements:
Microsoft .NET Framework 4.0 or 4.5 (Not 3.5)
Microsoft Office 2010 or Later for Office Toolkit Support

Windows Vista or Later for Windows Toolkit Support
Note: If you have already installed MS Office 2013 in your computer and activated it with any other license key, then I recommend you to uninstall MS Office 2013 completely from your computer and again do a fresh installation of MS Office 2013. After installing MS Office 2013, download the MS Office 2013 and Windows 8 activator from the link given below and run it to activate MS Office 2013 for lifetime.
