If you need to download v10.71, as of yesterday, it could still be found at the following link:
However, my personal experience has shown that while it seems stable with Windows 10 v1803 17134.320, as you upgrade to Windows 10 v1809 17763.1 (October 2018 upgrade), it does not seem to properly skin the frames of the PC Settings screens. The minimize, maximize, and exit buttons do not skin and work properly. So keep in mind that if you decide to install 10.71, when you upgrade to the new version of Windows 10, it does not work correctly. I have not tested 10.65 with the new Window 10 upgrade.
