[QUOTE=Sirtel;3970542]Hmm I use VPN pretty often and never a peep from Microsoft. /QUOTE]
VPN was all I could think of. I have an outlook mail account specifically for Amazon shopping so that if my main email is hacked, my Amazon account state safe. Out of the blue, Microsoft said suspicious activity and shut it until I went through some recovery process.
I would not fancy that for a whole pc.
Also had hassles with steam games and their steam guard system which locked me out of my own account for not entering a code correctly. That was a real pain to fix. Try contacting steam when you can't get into their app to message them!. Luckily i had one device where I was still logged in and got to them that way. Then I completely disabled steamguard once I was back in.
Those things are maybe not so bad if you live in USA, but if you are forced into some endless call centre phone queue at international call rates, it gets cheaper to. It a new pc instead after a while !
And some, (yes Google this is you) don't even have phone numbers.
There's a great x files episode in Final season s11e7 where all the automated services revolt after Mulder fails to tip properly...and they get locked out of everything...
