Windows Activation Confirmation Id







































This post will explain what the Windows 10 activation confirmation ID is, how to find it, and why you might need to refer to it. Microsoft introduced new technology in Windows 10 that changed the game when it comes to software licensing. In some ways it's a blessing as people can now download and install as many copies of Windows as they would like without having any worries about violating their license agreement - but on the other hand, Microsoft have also increased its ability to generate revenue from these licenses by introducing some very sophisticated mechanisms for tracking them. One of those mechanisms is a string of letters and numbers called a "Activation Confirmation ID" which identifies your unique installation of Windows on your computer. If you didn't change the default installation settings this ID will be pre-populated by Microsoft during the install process and it will be used as part of the activation process. If your computer is ever deactivated (taken offline) however, this ID can no longer be used and any future installations of Windows 10 will require a new ID. This is how it works: You first install Windows 10 on your computer. The installer adds a unique Activation Confirmation ID to your system, and saves it in an XML file (think of this as a registry key for software). This information may also be stored in OneDrive or similar cloud storage systems if you choose not to save it locally. The installer then runs a KMS (Key Management Server) service that generates a new Activation ID and uploads it to Microsoft's activation servers. (How does this work? There are now thousands of servers around the world that communicate with each other using complex algorithms to try to match the ID from your local machine against those in Microsoft's servers, and if two match, you're activated. In order for Windows 10 to be activated on your machine, you have to update this ID.) You then install any updates or new software, and once again run an installer that adds a new version of the same file, but now with a new Activation Confirmation ID appended to it. The installer then uploads this ID to Microsoft's activation servers. This will be compared to the previous one, and if they match you'll be activated. You may also want to update your computer's settings once in a while (for example, when you install an updated version of Windows). To do this you'll need to install the latest updates (currently available for Windows 10 version 1607), and then run the setup program that adds another version of the same XML file, but now with a new Activation Confirmation ID appended. This time around you're able to change your settings manually (if you've allowed it in the past), otherwise it will use Microsoft's defaults again. Once the installer has wiped the drive and added a new version of the registry, it will then upload that XML file to Microsoft's servers. The Activation ID you saved in the registry should be replaced by Microsoft with a new one, and any future installations of Windows 10 will require a new ID. Note: When you install Windows through a product key from an OEM, this ID is usually not pre-populated by Microsoft - therefore there may be no need to worry about it. eccc085e13
