CW: How long does RFM last?

Microsoft: RFM lasts until the user remedies the situation. In the event that a system is placed into RFM, there are several remedies available. First, the user can simply follow the prescribed activation process and options described above -- these include entering a new product key, obtaining a new product key or reentering the original product key. For volume-licensing customers, the user can return to normal Windows operating mode by connecting to a Key Management Service (KMS) service to automatically renew the activation or obtain a Multiple Activation Key (MAK). Finally, if the system is in RFM because of hardware changes, the user can restore the original hardware configuration. At any time in the process, a user can contact Microsoft support for additional help.

CW: Does RFM automatically log off users after a period of time?

Microsoft: In RFM, users are logged off of the Internet after one hour of usage.
