I use this in a virtual machine to test software in a “safe environment”. I sent an email to the seller, to see if they will send me another activation key. I am using this on a Hyper-V virtual machine. The Windows 7 license I am using on VMware is still working.
The seller is still active on eBay. I used Paypal and they give 180 days to dispute a transaction which I am still within. So thank you for the timely heads up. It actually came to $6.46.
I run miners in the winter - free heat. :)
Used to do the same as you, and ran machines for testing apps, etc., before going Galt.
