The keymanagementsoftware TSObjektkey 5 in its current version runs fine under Windows 10. We did those tests back in february 2015 for the first time and last week again with the latest known version.
The screenshots from the first test of TSObjektkey 5 are available on my gallery site. They were made with the German version of the keymanagement software. As the language of the program can be switched dynamically, screenshots are very similar.
The software TSObjektkey 5 also supports the upcoming new office on windows 10, as it already did with those from 2002 up to 2013.
