Activation and Product Licensing Policies
How many installations can be made with one product license? Has this changed with the introduction of Product Activation?
The underlying principles of Microsoft's software licenses have not changed. Microsoft's End User License Agreements (EULAs) have always stipulated the number of PCs that software can be installed on. Product Activation does not change that. Office XP or Office 2003 may be installed on one PC. The primary user of Office may also install one copy on a laptop computer for their exclusive use. To install Office XP or Office 2003 on more than these two devices, another license of the product must be acquired. Licenses for Office XP or Office 2003 acquired preinstalled on a new PC are single-PC licenses that cannot be transferred or installed a second time on another PC or laptop computer. Windows XP may be installed on one PC. There are no secondary use rights (e.g. no "laptop clause") in the Windows XP EULA. The aforementioned licensing terms have not been changed due to Product Activation. Some special licensing programs (such as the Microsoft Developer Network) provide additional licensing terms. Please check your specific license agreement or EULA for specifics. Re-installation and re-activation on the same PC can be done an unlimited number of times. Pricing and licensing details are available for Windows XP and Office 2003.
