I have vista and 7 installed side by side, and i tried running the 7's wmp, it complains about the version, i can change that in the registry but i'm too afraid to proceed, can someone please try that for me? with extended kernel and all the dlls replaced (wmp.dll,wmploc.dll,wmpps.dll,wmploc.dll.mui) i believe that's possible, don't want the risk of permanent damage tho.
