Windows 8 sound theme registry !!! - Windows 8

Hi guys,

My laptop runs windows 8 home premium 64-bit, and i am using the original theme all the time. Yseterday i downloaded a windows 7 theme and actually i really like it. After i installed the theme lead to my windows 8 default sound theme icon have yellow exclamation mark!!! I think may be my windows 8 sound theme registry was changed.

Who have windows 8 sound theme registry? If the problem is not about registry, what should i do? I am waitting for your reply.

My PC runs windows 7. I read some where windows 7 and window 8 theme installation is same. Is it true? Can any one give brief note on windows 7 and 8. Thanks for sharing.

Regards
