Astrill is a popular VPN service that offers a range of VPN versions, including a Windows-based one. However, I don't have specific information about a "Windows version" of the Astrill VPN. It's possible that you may be referring to a specific version or regional variant of the service. If you're looking for a VPN that provides a Windows version, I recommend checking the official website of Astrill (https://www.astrill.com) for the most up-to-date information. If they don't have a dedicated Windows version, you might want to explore other VPN services that offer Windows-based versions, such as: 2. OpenVPN (https://openvpn.org) - A free VPN that supports Windows and offers a range of features. 3. OpenVPN Server (https://openvpn-server.org) - Another free VPN service that supports Windows.

If you're looking for a paid VPN that offers Windows versions, you can visit their official website and explore their pricing plans.

If you're unable to find a specific version of the Astrill VPN, I recommend contacting their support team for assistance.
