First to say this is not my service and also i'm not affiliate but offer is very good.You'll get KVM VPS 1$/Month for first 3 months,after that 10$ is price.
So 3 months for 3$ and only linux is available at this price,for windows licence is needed and as I understand you need to buy it with VPS(doesn't metter you may have valid licence)
KVM VPS just 1$/month
20 GB Disk Space
1024 MB RAM
1 CPU Core(s)
