KMS ACTIVATOR WINDOWS 7,8,8.1, MS OFFICE 2013,2010 ACTIVATOR




Microsoft Product Activation is a DRM technology used by Microsoft Corporation in several of its computer software programs, most notably its Windows operating system and its Office productivity suite. The procedure enforces compliance with the program's end-user license agreement by
transmitting information about both the product key used to install the program and the user's computer hardware to Microsoft, inhibiting or completely preventing the use of the program until the validity of its license is confirmed.

The procedure has been met with significant criticism by many consumers, technical analysts and computer experts, who argue that it is poorly designed, highly inconvenient and ultimately does nothing to prevent software piracy. The process has been successfully circumvented on multiple occasions.

When installing a retail copy of Windows or Office, the user is asked to input a unique product key supplied on a certificate of authenticity included with the program, which is later verified during activation. Immediate activation is not required following installation, but the program must be activated within a specific period of time in order to continue to function properly. Throughout this grace period, the user will be periodically reminded to activate the program, with warnings becoming more frequent over time.


Certain versions of Windows and Office are available under a volume license, where a single product key is used for multiple installations. Programs purchased under this license must still be activated, with the exception of Windows XP and all versions of Office released prior to Office 2010. Businesses using this licensing system have the option of using Microsoft's activation servers or creating and managing their own.

If Windows is pre-installed on a computer by an original equipment manufacturer (OEM), the operating system is automatically activated without the need for interaction from the user.[10] In this case, the copy of Windows installed does not use the product key listed on the certificate of authenticity, but rather a master product key issued to OEMs called a System Locked Pre-installation (SLP) key. On each boot, Windows confirms the presence of specific information stored in the BIOS by the manufacturer, ensuring the activation only remains valid on that computer, even if the product key is used on another machine.

After grace period

If activation is not performed within the grace period or fails because of an illegal or invalid product key, the following restrictions will be imposed on the user:

    In Windows XP, Windows Server 2003 and Windows Server 2003 R2, after a grace period of 30 days, the operating system cannot be used at all until the activation process is completed successfully.


    In Windows Vista, after a grace period of 30 days, the operating system will boot only into a reduced functionality mode. The reduced functionality varies based on whether the operating system is simply out of grace or has undergone a failed activation. In the former case, built-in games and premium features like Windows Aero are disabled, and the system is rebooted every hour; in the latter case, certain premium features are disabled and some content is not available from Windows Update.

    In Windows Vista SP1, Windows 7, Windows Server 2008 and Windows Server 2008 R2, after a grace period of 30 days (60 days for Windows Server 2008), the operating system will add a text message in the bottom-right hand corner of the screen stating that the copy of Windows in question is not valid, set the desktop background to black, allow only critical and security updates to be downloaded from Windows Update and give periodic reminders to activate the operating system. However, the operating system otherwise functions normally.
    In Windows 8, Windows 8.1, Windows Server 2012 and Windows Server 2012 R2, the 30-day grace period has been removed. If the operating system is not activated, there is a watermark showing the edition of Windows (although it does not show to activate) on desktop, personalization features in PC Settings like changing the lock screen is disabled. Entire Screen notification appears periodically. However, the operating system otherwise functions normally.[citation needed]
    In Office XP, Office 2003, Office 2007, Office 2010, and Office 2013, after a grace period of 30–60 days for Office 2010 and 14–60 days in Office 2013 or opening the program 25 times for Office 2007 and 50 times for Office 2003 and XP, the programs will enter a reduced functionality mode, where files can be viewed but not edited.

When activation takes place, the program saves a record of the verification data in the user's computer. If the system is booted up with significant hardware changes, the application will likely require reactivation to prevent the same copy of the program being installed on two different systems.


During activation
Activation is performed with a utility supplied with Windows and Office called the Activation Wizard. It can be performed either over the Internet or by telephone. When activating over the Internet, the Activation Wizard automatically transmits and receives verification data to and from Microsoft servers, completing the process without any interaction by the user. Activation by telephone requires that a user and a Microsoft agent verbally exchange activation information. In this case, an installation ID is generated, which is then read to the agent. The agent verifies the information and replies with a confirmation ID, which is then typed into the Activation Wizard.
The Activation Wizard generates verification data primarily based on information about hardware in the computer. In Windows XP, information about the following eight categories of hardware is included:


    Display adapter
    SCSI adapter
    IDE adapter
    Network adapter MAC address
    RAM amount range (e.g. 0-512 MB)
    Processor type and serial number
    Hard drive device and volume serial number
    Optical drive (e.g. DVD-ROM)

The verification data is also based on the product key entered during activation. In some cases, the product key is checked against a list of known illegally distributed keys.

Certain retail copies of Windows and Office sold in certain countries classified as emerging markets have geographical activation restrictions, which only allow the user to activate the product within the indicated region.

After activation

If activation completes successfully, the user can continue to use the application without any further issues or impediments.
