Apparently, older versions of DirectDraw are broken on Windows 8, 8.1 and the Windows 10 Tech preview. So I assume you tried viasil it will be broken on the retail version of Windows 10 as well.
I didn't find any answer about this on the Jazz Jackrabbit 2 faq so please close this in case a solution has been provided already.
There's a small utility called ddwrapper on http://bitpatch.com/ddwrapper.html to solve this problem. It works by intercepting calls of applications and games just like the real DirectDraw library. And this should work for other old games too. You just need to download the package on the site and unzip it on your Jazz2's folder and edit the "aqrit.cfg" file.
This is my config
Code:
;;; www.bitpatch.com ;;;
RealDDrawPath = AUTO
BltMirror = 0
BltNoTearing = 0
ColorFix = 1
DisableHighDpiScaling = 0
FakeVsync = 0
FakeVsyncInterval = 0
ForceBltNoTearing = 0
ForceDirectDrawEmulation = 1
NoVideoMemory = 0
SingleProcAffinity = 0
ShowFPS = 15
After that, start Jazz2 and it should work as speedy as on Windows 7 and earlier.
The sourcecode is included with the tool.

I had hardware acceleration enabled in my settings Disabled and the game runs fine!
