How can this be rare if the user is supposed to test things after the 
upgrade? I didn't think about it but it's actually risky - every 
application can potentially be non-forward-compatible. Users should be 
adviced to use the guest user account to test new applications, or 
perhaps it can be done in a way that only a special account sees the new 
system?
