in my opinion sadly the only thing you will experience from microsoft hotline is a waste of your time, and / or money.
my reasons were based on the following. i was transferred to three different reps, each of which i was asked my full name, phone number, email, edition of windows and reasons...
bios update
consumer rights
customer service
dissatisfaction
hotline
issue resolution
key validation
microsoft
phonecall
review
support reps
tech support
technical issues
time wasting
user experience
