Just loaded MM 4.07 and it works fine in W10-10049. The only issue compared to MM3 (rounded edges in W10-10049, btw) is that the edges are no longer rounded as they were in the prior version of MM and W10-10041. Library conversion was seamless.

Thanks for moving the topic.
Finally got 10041 loaded so that everything is good in W10. I did find that burning the DVD should be done at 4X rather than 16. Media Monkey is very stable and configured as I wanted it to. Next step is to try using the current version of MM.

Thank you for marking the move properly, peke.

Moved into news, I've also installes Win 10 Tech but I'm on 10049 build.I like how things are working. No issues for now.

The Technical Preview of Windows 10 is in full testing mode. So far version 10041 works with all of my hardware. What is more important is how it performs with Media Monkey 3.2. (That's not a typo) I prefer the interface and ease of use of this older version for the most part. I do not do video.
The install of 3.2 went perfectly as did my add-on skins. For those who are curious, W10 has a Music folder staring one in the face. I use my own in the root directory instead. Loaded 24Gigs of FLAC files and every one of them is now in the Library and ready to play.
The plan for now is to continue to test W10 and also version 4 of Media Monkey.

(If this is in the wrong place - please move it)
