This works and is secure!
:o:As a Microsoft Certified Engineer for more that 30 years this is what I do.
What is the main software that you are using, also most of the reasons Microsoft stops supporting Operating systems is for guess what $$$$$$$$$$$$$. The most security issue with Microsoft is Internet Explorer and old office.
I still use XP Pro with OPENDNS DNSCrypt also for Browser Comodo Dragon, also a free VPN like VPNReactor and SecurityKISS Tunnel. The Office can be replaced with free Kingsoft Office, for Email Mozilla Thunderbird it looks for spam and other junk. Make sure all of your Virus and software like Advanced Systemcare is looked at daily.
Any questions let me know.
