Downgrade iTunes 12.7
I've been running iTunes on Windows 10 for a few years without incident. Today I upgraded from iTunes 12.6.2 to 12.7. Performance on 12.7 is so poor, iTunes is now unusable for me. I completely uninstalled iTunes and all the other iTunes related applications, I deleted my iTunes folder, downloaded the 12.7 executable from Apple and reinstalled 12.7, but performance is still horrible. I store my library on a network attached storage device, but as I said, I have been using iTunes for years on Windows 10 without incident in the same configuration. I always had good performance.
Apple's download site does NOT have the stand-alone iTunes 12.6.2 Windows installer, that version of 12.6.2 you can download from Apple is for MacOS not Windows (it's a DMG file not an .exe). I know there are several sites that cache previous iTunes Windows (.exe) standalone installation files, but I am nervous about using one of those files for fear of modification by hosting site.
Does anyone know where I can source the pervious iTunes Windows stand-along .exe install file? I think version 12.6.2.20 was the previous version prior to 12.7?
