There is a recent thread in this forum on that type of subject.
Please review and consider its comments in context to the specifics of Premiere Elements 10 on Windows 10.
Although some are very optimistic regarding Premiere Elements on Windows 10, I am still guarded on my remarks on the subject.
My approach is going to be to use Windows 10 on a secondary computer until I am confident of no problems with my prime applicatons on Windows 10. What I am hoping to do is to set up my computer for dual boot so that I can retain Windows 7 or 8.1 on the same computer with Windows 10.
