MUND litestep skin was built for Win8, but unfortunately i dont have Win8 to try it.
On Win7, litestep installation is bit tricky.
You probably have to read these 2 journal for installation steps,
Aaron's journal and
Mangosango's journal.
For PKFRST Suite, i think the most important thing is to get true transparency skin to work. And (again), it's also tricky to get it work on Win7 (especially on 64-bit), check
this journalBut the good thing is true transparency seems to work flawlessly on Win8. Check ~
dafmat71's shots to see how it works on Win8.
I hope that helps
