I'm using Hoxx VPN Proxy, Completely free but if you want to be a premier user only 40$ for a year and they accept bitcoin and paypal.
This thread isn't talking about VPN's, it's discussing VP
S' (virtual private servers).
OP, I don't think you'll find a Windows Server VPS for $1 a month (it looks like most places charge ~ $5 USD per month for a Windows VPS), but if $1 a month is your budget
you can get a half-decent Linux VPS for $11 annually.
