I am thinking windows 7 was maybe the best.

Win 7 was the last MS OS I will ever own. I found Win 7 had a USB device detection bug where a flatbed scanner would work on one port but not another.

Then the installed a "Security Update" (that was actually prepping the OS for upgrade to ver 10) which caused Corel Video Studio to not work. I turned off all updates because of that, but decided a non updated OS wasn't a great idea either.

So, I wiped the hard drive and installed Linux Mint 17, which was the current version then. Now the only Windows only application I use is Family Tree Maker, which I run in a Win 7 virtual machine. That's a lot of storage for one program, but nothing I can do about that at this time.
