How to Recover from Reduced Functionality Mode (RFM) in Vista

Microsoft allows you to install and use Windows Vista for evaluation without license or product key for up to 30 days. Within these 30 days, you must activate the Vista system with a valid product key. Else, if you forget to activate your computer, or you’re using illegal and pirated product key, Windows Vista will go into Reduced Functionality Mode (RFM), where you basically can no longer use the system for productivity works until you successfully activate Vista with a licensed product key.

Windows Activation

Activate Windows Now

Your activation period has expired and Windows is no longer working.
To use Windows you must activate this copy of Windows.

If you’re still not yet ready to activate your copy of Vista and want to further extend the activation period another 30 days, and also want to exit or recover from Reduced Functionality Mode so that you can continue using Vista without reinstalling, here’s a simple hack to crack the RFM. The trick is made possible by Microsoft which still allow users to use Internet Explorer in RFM (probably do so so that you will can buy a license online), which can be used to break out of Reduced Functionality mode by running an explorer interface to open an administrative level command prompt and run the commands required to reset your activation period and recover use of your computer and desktop.
