As a heads up, Start8 isn't fully working on Windows 10. The modern apps list is no doubt blank, the jumplists will be non functional and if you have the taskbar search field enabled it will be overlapping the left most running apps. There are other issues, but those are the big ones assuming your Windows 10 install is the current release.
Funny thing, the modern apps list is fully functional. I disable Cortana completely because it's dumb, so the app doesn't interfere with it, and I don't even know what a jumplist is. Everything functions, as far as I can tell, as well as it did in Windows 8.1. Honestly, the only reason I upgraded to Windows 10 from 8.1 was because my bootloader was jacked up and it was preventing me from using bitlocker. Upgrading fixed it, but at the cost of now I'm running Windows 10...
They may not bother you depending on your use case, but I thought I worth mentioning.
Thanks for mentioning it, I remember seeing a little warning that popped up when I upgraded to Win10 about Cortana and Start8 but I couldn't remember the incompatibilities. Now that I know that for me they are non-issues, I know I don't really need Start10 anyway.
