Windows XP and 7 were quite good versions I thought.
My machine uses XP, it never connects to anything, I also have a win7 laptop that does not connect to anything.
I have two suggestions,
1. Get an older system from ebay etc. and use that to run your scripts.
2. learn Python or better still move to C# and plugins. Anyone who knows VB should have no real problem moving to those, the worst thing is to move back and forth between them.
In 1971 the UK changed to decimai money, my grandmother used to constantly convert from new money to old money, I used to say, forget the old money just go with the new and she found that a lot easier.
