What if I reinstall software frequently, do I need to activate the software each time?
We understand that MSDN subscribers have unique needs, so we have included special activation privileges for MSDN subscribers.
MSDN Subscription product keys can be used to activate up to 10 PCs.
Although you must go through the activation process each time you reinstall on the same PC, your total number of activations will not be decremented.
For Windows, MSDN subscribers have a 60-day grace period before the product must be activated. If you will be reinstalling the software in less than 60 days, you do not need to activate it. Please note that Windows Update and Windows Genuine Advantage require that the installation be activated.
For Office 2003, MSDN subscribers have 50 launches before the product must be activated.
Software may be reinstalled on the same machine as many times as needed without reactivating it. However, if the hard disk is reformatted prior to reinstallation, reactivation may be required however the total number of activations will not be decremented.
