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.

Businesses using this licensing system have the option of using Microsoft's activation servers or creating and managing their own. 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. Ĭertain versions of Windows and Office are available under a volume license, where a single product key is used for multiple installations. Throughout this grace period, the user will be periodically reminded to activate the program, with warnings becoming more frequent over time.

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. Use the interactive lookup tool to find product keys for your Autodesk products.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. With every new release, Autodesk publishes a list of the product feature codes for that year. Here is an example of a feature code in a log file entry:ġ1:00:04 (adskflex) OUT: "87393ACD_2021_0F" you create an options file to manage your network license usage, you must know which feature code maps to which product. Autodesk product feature codes appear in license files, debug log files, options files, support articles, and more. So, all products need unique identifiers. However, the last one is a unique feature code for every new product release.įeature codes are necessary because NLM administers licenses for hundreds of Autodesk products and versions. The first two don’t change from one release to the next: 64300ACD always indicates AutoCAD. For example:Ħ4300ACD_F indicates a perpetual license of AutoCAD on a maintenance plan.Ħ4300ACD_T_F indicates a subscription of AutoCAD with multi-user access.Ĩ7393ACD_2021_0F indicates a specific product and version: AutoCAD 2021. Feature codes come in three types: product-specific on a maintenance plan, product-specific subscription with multi-user access, and product version-specific.
