These are meant for testing IE11 and Microsoft Edge Legacy, but they are also fully-functional copies of Windows (expire in 90 days). So that means you can install Chrome and WS in them. Useful if you want to isolate your web scraping, or if you want to use proxies/VPNS separately from your main browser.
VirtualBox is also free:
Be aware of RAM and CPU requirements though. You'll need about 3GB RAM per Windows VM for scraping.
