Hi and welcome to Eight Forums,
Seeing this gave me memories, especially that dog and wizard guy animation when u tap search, lovely old days! Alright, in my opinion the new search features are more accurate and easier to use, i have no idea why you want such old panel to use, and i don't think anyone bothered to mod the explorer.exe file to add this but if i am not wrong there is similar programs that u can get and will probably have the exact same search panel, if i can find one ill make sure to update u with the link.
